2023-01-05 Alex Tutubalin <lexa@lexa.ru> LibRaw 0.21.1-Release * fixed typo in panasonic metadata parser 2022-12-18 Alex Tutubalin <lexa@lexa.ru> LibRaw 0.21-Release * Multiple fixes inspired by oss-fuzz project 2022-07-01 Alex Tutubalin <lexa@lexa.ru> LibRaw 0.21-Beta1 == Camera format support == * Phase One/Leaf IIQ-S v2 support * Canon CR3 filmrolls * Canon CRM (movie) files * Tiled bit-packed (and 16-bit unpacked) DNGs * (non-standard) Deflate-compressed integer DNG files are allowed == Camera support == * Canon EOS R3, R7 and R10 * Fujifilm X-H2S, X-T30 II * OM System OM-1 * Leica M11 * Sony A7-IV (ILCE-7M4) * DJI Mavic 3 * Nikon Z9: standard compression formats only == Multiple (resolution) thumbnails support == * New imgdata.thumbs_list data item with data fields: int thumbcount: thumbnail count libraw_thumbnail_item_t thumblist[LIBRAW_THUMBNAIL_MAXCOUNT]: list of thumbnails libraw_thumbnail_item_t fields: enum LibRaw_internal_thumbnail_formats tformat: internal thumbnail format (this is not PPM/JPEG, but internal type related to thumbnail reading/unpacking method) ushort twidth, theight: thumbnail image size. ushort tflip: image rotation (see notes below) unsigned tlength: on-disk data size (not uncompressed for compressed formats) unsigned tmisc: bit depth and channel count: (color << 5) | bitsperpixel INT64 toffset: Thumbnail data offset in file Notes: - Only TIFF-based and CR3 files are parsed for thumbnail list, other formats will have thumbcount = 1 (or 0 if no thumbnail found in file). - Thumbnail image size may be unknown (not recorded in metadata), in this case twidth and theight are zero. Usually small(er) thumbnails will always have twidth/theight filled, while largest one may have these fields set to zero. - Thumbnail rotation (tflip) is filled only for TIFF-based RAWs (if Orientation tag is not present in IFD, default zero value is used) For non-tiff images, tflip is initialized to 0xffff (not known...) - There is no code to select thumbnail based on some criteria (e.g. minimal resolution), it is left to user to implement such a criteria, if needed (see unpack_thumb_ex() call below) - If you want to get largest possible thumbnail: just use old unpack_thumb() call to get it. * new API call: LibRaw::unpack_thumb_ex(int i): Unpacks i-th thumbnail if it exists into imgdata.thumbnail structure i should be non-zero and less then imgdata.thumbs_list.thumbcount. * samples/simple_dcraw.cpp: new -E command line switch to extract all thumbnails from input file(s) == (Experimental) RawSpeed "version 3" (develop branch) support. == Build with -DUSE_RAWSPEED3, see details in RawSpeed3/README.md LibRaw::capabilities will set bit LIBRAW_CAPS_RAWSPEED3 if compiled w/ RawSpeed-v3 support If file was processed (or tried to process) via RawSpeed-v3, these bits are raised in imgdata.process_warnings: LIBRAW_WARN_RAWSPEED3_PROCESSED - processed via RawSpeed v3 LIBRAW_WARN_RAWSPEED3_PROBLEM - not processed (due to exception in RawSpeed library) LIBRAW_WARN_RAWSPEED3_UNSUPPORTED - unsupported file LIBRAW_WARN_RAWSPEED3_NOTLISTED - file not listed in cameras.xml data RawSpeed-v3 support is controlled via libraw_decoder_info.t->flags (LIBRAW_DECODER_TRYRAWSPEED3 bit). The bit is set for: - lossless jpeg decoder - Canon sRAW decoder - lossless compressed and packed-compressed DNG decoders - Pentax decoder - Nikon (compressed) decoder - Phase One Compressed and Hasselblad/Compressed decoders - bitpacked decoder - Panasonic (old 12-bit compression) decoder - Olympus decoder - Sony ARW (v1 and v2) decoders - Samsung (version 1) decoder * (Experimental) Fine control of RawSpeed version selection/use. To enable, build LibRaw with -DUSE_RAWSPEED_BITS LibRaw::capabilities will set bit LIBRAW_CAPS_RAWSPEED_BITS if compiled with this flag. If enabled: imgdata.rawparams.use_rawspeed becomes bit-field (instead of 0/1 off/on) with bits: LIBRAW_RAWSPEEDV1_USE - use RawSpeed Version 1 (if compiled with) LIBRAW_RAWSPEEDV1_FAILONUNKNOWN - do not process unknown files (not listed in RawSpeed v1 camera definitions file) LIBRAW_RAWSPEEDV1_IGNOREERRORS - ignore mirror decoding errors (out of range data,etc) LIBRAW_RAWSPEEDV3_USE - Use RawSpeed Version 3 (if compiled with) LIBRAW_RAWSPEEDV3_FAILONUNKNOWN - do not process unknown files LIBRAW_RAWSPEEDV3_IGNOREERRORS - ignore minor decoding errors == Misc changes/improvements == * New compile time define LIBRAW_OWN_SWAB to use on platforms without swab() in C/C++ runtime * New imgdata.rawparams.options bit: LIBRAW_RAWOPTIONS_CANON_IGNORE_MAKERNOTES_ROTATION If set: image orientation is set based on TIFF/IFD0:Orientation tag, makernotes orientation data is ignored * Nikon makernotes: read NEFCompression tag for HE/HE* files * Nikon orientation tag: more fixed offsets for known cameras * Adobe DNG SDK 1.6 support (meaning, just an additional patch for GPR SDK) * removed LibRaw::memerr(), memory allocation failures are already handled in LibRaw_memmgr::*alloc w/ exception thrown * removed memory error callback, out-of-memory error should be handled via returned error code check, all related parameters (e.g. LibRaw constructor option to not set such callback) is also removed * imgdata.params.adjust_maximum_thr is settable via C-API libraw_set_adjust_maximum_thr(..) * New rawoptions/processing flags for DNG processing if compiled with Adobe DNG SDK: LIBRAW_RAWOPTIONS_DNG_STAGE2_IFPRESENT,LIBRAW_RAWOPTIONS_DNG_STAGE3_IFPRESENT If these flag(s) are set: Stage2/Stage3 processing will be performed only if OpcodeList2/OpcodeList3 tags are present in the input DNG file Old (hard) flags (LIBRAW_RAWOPTIONS_DNG_STAGE2 and LIBRAW_RAWOPTIONS_DNG_STAGE3) are not removed and will force Stage2/3 processing if set (regardless of input file tags) * New imgdata.rawparams.options bit: LIBRAW_RAWOPTIONS_DNG_ADD_MASKS If set: DNG Transparency Masks will be extracted (if selected via shot_select) * New decoder flag: LIBRAW_DECODER_UNSUPPORTED_FORMAT == Bugs fixed == * Fixed possible out-of-buffer read in Nikon orientation tag parser * Windows datastream: fixed logic errors (not showing up in real life) * Out-of-range read-only array access in postprocessing if output_color is set to 0 (raw color) * Minolta Z2 was not recognized correctly on 32-bit systems * Fixed possible buffer overflow in Kodak C330 decoder * dcraw_process(): check for buffer allocation results to avoid NULL deref 2021-10-11 Alex Tutubalin <lexa@lexa.ru> * Camera support: Apple iPhone 13 Pro GoPro HERO10 (if compiled w/ USE_GPR_SDK) Ricoh GR III Sony Xperia 1 III * Fuji RAF files: XMP block extraction * Fixed a typo in LIBRAW_OPTIONS_* flag names (was LIBRAW_OPIONS, old flags names not removed due to compatibility) * samples/raw-identify.cpp: -v flag documented in usage print. 2021-09-14 Alex Tutubalin <lexa@lexa.ru> * Camera support: Fujifilm GFX 50S II Nikon Z fc Sony A7R-IIIA (ILCE-7RM3A), A7R-IVA (ILCE-7RM4A) * API/datastruct Changes: - imgdata.params.shot_select moved to imgdata.rawparams.shot_select (because this is decode-time option, not postprocessing option) - libraw_open_bayer(...) added to C-API - imgdata.makernotes.canon: separate SensorLeftBorder,SensorTopBorder.... (and many other datafields) are united in libraw_area_t (rectangle) groups for crop areas and optical black areas. * src/libraw_cxx.cpp completely removed from source tree to not confuse users. (also all mentions are removed from Makefiles) * Better Olympus makernotes parsing: LiveND mode, Panorama mode tags. * clang-cl compatibility: - defines _MSC_VER, but _forceinline is not supported - warnings eliminated in Windows buffered datastream * Canon/12-bit files: adjust color.linear_max and makernotes.canon values to match data range. 2021-08-04 Alex Tutubalin <lexa@lexa.ru> * Camera support: Sony ZV-E10 * DNG/Floating point: additional metadata check to refuse ambiguous/corrupted files. * DNG/Floating point: correct handling of striped files (never seen in wild) * Rawspeed support: disallow Nikon D6/Compressed processing * Bug fixed: raw_inset_crops[] ctop/cheight was not adjusted right if vendor-specified ctop equals to 1. 2021-07-20 Alex Tutubalin <lexa@lexa.ru> * Camera support: Olympus E-P7 2021-07-08 Alex Tutubalin <lexa@lexa.ru> * Camera support: Panasonic GH5 Mark II Pentax K3 Mark III several phones w/ DNG files (checked) * Camera format support: Panasonic v6/12 bit * Compile-time raw size limits implemented: LIBRAW_MAX_NONDNG_RAW_FILE_SIZE - max file size for non-DNG files (default: 2GB - 1 byte) LIBRAW_MAX_DNG_RAW_FILE_SIZE - max DNG file size limit (4GB-1 if compiled w/ DNG SDK, 2GB-1 otherwise) * ACES output: color conversion changed to provide D65 white point * Fix for Canon 5D Mark II/sRAW1 incorrect camera provided crop 2021-05-07 Alex Tutubalin <lexa@lexa.ru> * Camera support: Fujifilm GFX 100S, X-E4: improved color data Canon EOS M50 Mark II was supported but not listed in camera list DJI Mavic Air 2S GOPRO Hero9 * Support for RaspberryPi HQ camera (if compiled w/ USE_6BY9RPI) * Improved support for RPi V1/V2 cameras: - white balance data extraction - color matrix extracted to imgdata.color.cmatrix to use with use_camera_matrix. - full-size thumbnail/preview support for JPEG+RAW files (raspistill -r) * Fuji GFX100/GFX100S: PixelShift metadata extraction. * RawSpeed (master): fixed bug in old Samsung/compressed decoder, apply this patch to RawSpeed: RawSpeed/rawspeed.samsung-decoder.patch * DCI-P3 and Rec 2020 output colorspaces * Eliminated multiple signed/unsigned mismatch warnings (reported by gcc11) * fixed possible 1-byte stack underrun while handling text tags with zero length * XMP block size in CR3 files limited to 1MB * Preview block size in CR3 files limited to 100MB * Fixed wrong handling of linear DNG files created from Pentax out-of-camera DNGs 2021-02-18 Alex Tutubalin <lexa@lexa.ru> * Improved Phase One Compressed defects masking, thanks to Alexey Danilchenko * Sony ILCE-1/Lossless compressed support 2021-02-16 Alex Tutubalin <lexa@lexa.ru> * Additional fields in libraw_internal_data.unpacker_data: - INT64: exif_offset: base offset of 1st EXIF IFD in file - INT64: ifd0_offset: base offset of 1st TIFF IFD (IFD0) in file - unsigned cr3_exif_length, cr3_ifd0_lenght : CR3-specific length of exif and ifd0 sections. 2021-02-08 Alex Tutubalin <lexa@lexa.ru> * CRX (CR3) decoder: fixed typo in constant; this does not affect any known still photo (CR3) sample(s), but allows to use the decoder with some video (CRM) files. * Imported user-contributed improvements to OpenMP postprocessing (AHD and X-Trans demosaic) * Bugfix: overwrite (wrong) TIFF/Orientation tag value with Metadata/Camera Orientation value for EOS 40D only. 2021-02-04 Alex Tutubalin <lexa@lexa.ru> * imgdata.sizes.raw_inset_crop rearranged: now it is imgdata.sizes.raw_inset_crops[2]: - item at [0] is the same as imgdatra.sizes.raw_inset_crop in previous versions - item at [1] is 'user crop', in particular: -- set by DNG DefaultUserCrop tag -- or set via raw aspect ratio tags (e.g. 16:9 aspect on Fujifilm cameras) raw_inset_crops[1] is filled only if aspect ratio tags provides different aspect ratio compared to raw_inset_crops[0]. There are no flags to check if raw_inset_crops[Nth] is filled; to see if it is filled check the values of: ctop/cleft < 0xffff (0xffff => standard values if not initialized) ctop+cheight <= sizes.raw_height cleft+cwidth <= sizes.raw_width Note: raw_inset_crops may be fooled by metadata (makernotes), use some correctness check before use. * LIBRAW_RAWOPTIONS_USE_DNG_DEFAULT_CROP processing flag removed, DNG DefaultCrop* tags are parsed into raw_inset_crops[0] * new LibRaw call LibRaw::adjust_to_raw_inset_crop(unsigned mask, float maxcrop = 0.55f) Promotes imgdata.sizes.raw_inset_crops[] values to imgdata.sizes.*margin and imgdata.sizes.width/height fields mask: if bit 1 is set: prefer raw_inset_crops[1] if bit 0 is set: prefer raw_inset_crops[0] maxcrop: limits crop to not less than (original width/height)*maxcrop; if raw_inset_crops[i] data results in tighter crop, than this item is ignored. return value: index in raw_inset_crops[] used increased by one, so 0: no changes made 1: [0]th data used 2: [1]th data used Note: this call SHOULD be used after LibRaw::unpack(), otherwise black level calculation from masked area may be fooled resulting in wrong black levels. 2021-01-21 Alex Tutubalin <lexa@lexa.ru> == LibRaw snapshot 202101 == = Camera format support: = Lossy compressed CR3 files Lossy compressed RAF files Uncompressed floating point DNG files (16-24-32 bit) Deflate compressed striped DNG files XMP and HEIF-preview extraction from CR3 files = Camera support = Apple iPhone 12 Max, iPhone 12 Max Pro Canon EOS R5, EOS R6, EOS 850D, EOS-1D X Mark III (lossy compressed files) FujiFilm X-S10 Hasselblad CFV II 50C", Leica M10-R, Q2 Monochrom, S3, SL2-S Nikon Z 5, Z 6 II, Z 7 II Olympus E-M10 Mark IV Panasonic DC-G100 / G110, DC-S5 Sony ILCE-7C (A7C), ILCE-7SM3 (A7S III) Zeiss ZX1 Plus multiple DNG-recording cameraphones/drones/etc. = Almost dropped camera support: = Old/partially supported video/cinema cameras support is available only if LibRaw is compiled with USE_OLD_VIDEOCAMS defined (this #define is converted internally to LIBRAW_OLD_VIDEO_SUPPORT defined). This affects: Arri cameras Canon C500 RED Cine cameras We plan to keep the support in LibRaw 0.21 (if compiled with define mentioned above) and completely drop the support after 0.21. If you're using LibRaw to decode RED Cine files, see LibRaw*datastreams section below (in short: you'll need to use old fstream-based datastream under Windows). Cinema DNG files are not affected by this. = API/ABI changes = * Decoding parameters imgdata.params is split into imgdata.rawparams: parameters used for metadata/raw data decoding imgdata.params: parameters used at postprocessing stage imgdata.params.raw_processing options are split into two sub-options sets imgdata.rawparams.options: raw processing flags, useful for normal operations imgdata.rawparams.specials: special modes (e.g decoding only delta pixels from Sony ARW) Old LIBRAW_PROCESSING_* flags are renamed to LIBRAW_RAWOPTIONS_* and LIBRAW_RAWSPECIAL* LIBRAW_PROCESSING_DP2Q_INTERPOLATE... flags are renamed to LIBRAW_RAWSPECIAL_NODP2Q_INTERPOLATE with inverted meaning (with the goal to have zero imgdata.rawparams.specials in normal use). * New processing flag LIBRAW_RAWOPTIONS_PROVIDE_NONSTANDARD_WB If set (default is not), and when applicable, color.cam_mul[] and color.WB_Coeffs/WBCT_Coeffs will contain WB settings for a non-standard workflow. Right now only Sony DSC-F828 is affected: camera-recorded white balance can't be directly applied to raw data because WB is for RGB, while raw data is RGBE. * New processing flag: LIBRAW_RAWOPTIONS_CAMERAWB_FALLBACK_TO_DAYLIGHT If set (default is not), LibRaw::dcraw_process() will fallback to daylight WB (excluding some very specific cases like Canon D30). This is how LibRaw 0.19 (and older) works. If not set: LibRaw::dcraw_process() will fallback to calculated auto WB if camera WB is requested, but appropriate white balance was not found in metadata. * Removed LIBRAW_PROCESSING_SKIP_MAKERNOTES processing flag: with new Windows(-handle) datastreams metadata parsing performance is enough to not skip makernotes parsing. * new output parameter: imgdata.params.output_flags and new enum LibRaw_output_flags Right now the only flag is implemented: LIBRAW_OUTPUT_FLAGS_PPMMETA setting it will result into metadata written to PPM/PGM output file * LibRaw_*datastreams change and corresponding open_file() parameters change LibRaw_file_datastream (based on iostreams) is moved under #ifdef LIBRAW_USE_DEPRECATED_IOSTREAMS_DATASTREAM Standard datastreams are: LibRaw_bigfile_datastream (FILE* based) for POSIX systems LibRaw_bigfile_buffered_datastream - for use with Win32 syscalls API changes: if LIBRAW_USE_DEPRECATED_IOSTREAMS_DATASTREAM is NOT defined, than LibRaw::open_file() and similar calls drops the last INT64 max_buffered_sz parameter which defines automatic selection between iostreams and FILE* based datasteams. Note: LibRaw_bigfile_buffered_datastream does NOT implements make_jas_stream() call, so RED Cine file decoding is not possible with this datastream. Use deprecaded iostreams implementation instead. We plan to keep LIBRAW_USE_DEPRECATED_IOSTREAMS_DATASTREAM up to LibRaw 0.21 and drop in 0.22. * Fuji decoder: fuji_decode_loop/fuji_decode_strip parameters has changed; look into source code for details if you're implementing your own fuji_decode_loop() call in subclass to provide parallel fuji decoding. * Canon CR3 H265 (HEIF) preview limited support: - new format value: LIBRAW_THUMBNAIL_H265 - this thumbnail is NOT extracted by LibRaw::make_mem_thumb() yet; * LibRaw::capabilities Two bits added: LIBRAW_CAPS_ZLIB if compiled with USE_ZLIB LIBRAW_CAPS_JPEG if compiled with USE_JPEG * Windows datastreams: CreateFile2 is used if compiled for UWP. * API-datastruct: clarified behavior with use_camera_wb=1 setting. * identify(): restored the differentiation between fsize and flen. * New compile-time LIBRAW_FORCE_OPENMP to skip compiler version check (if LibRaw user is absolutely sure that OpenMP is supported by compiler) 2020-10-14 Alex Tutubalin <lexa@lexa.ru> * LibRaw 0.20.2 Reverted 0.20.1 change: - const buffer for open_buffer() and open_bayer() calls Because of 0.20.0 ABI break 2020-10-14 Alex Tutubalin <lexa@lexa.ru> * LibRaw 0.20.1 * Improvements: - exif callback is called on EXIF GPS and EXIF Interop IFDs - open_bayer call documented - Canon (ColorDatsSubver==32): parse Specular White instead of hardcoded value * Fixes for normal files processing: - Olympus XZ-1: do not provide linear_max (it is wrong in metadata) - Nikon Z cameras: added space in camera list - raw-identify: fixed wb-preset print - Pentax Optio 33WR: maker index was incorrect - dcraw_emu: corrected help line for -6 option. - raw-identify: corrected range check for color matrices print - use_camera_matrix option: fixed a bug introduced when making compiler more happy. * Fixes for damaged/special crafted files processing: - Fix for truncated CR3 files parsing - DNG metadata merger: all color loops are limited to MIN(4,colors) - Check for marings: should be less than raw image size - Check for xmpdata present in Samsung Lens ID assignment - Check for column range in leaf_hdr decoder - Additional checks in Hasselblad model parser - Fuji rotate: better limits check - DNG files: limit tiff_samples * Not fixes, but makes ASAN/compilers/etc happy: - corrected GPS EXIF output - const buffer for open_buffer() and open_bayer() calls 2020-07-23 Alex Tutubalin <lexa@lexa.ru> * LibRaw 0.20 == Camera Format support == Canon CR3 GoPro (via GPR SDK) Panasonic 14-bit Fujifilm compressed/16bit Rapsberry Pi RAW+JPEG format (if USE_6BY9RPI defined) Foveon X3F support changed: it is supported only if USE_X3FTOOLS defined at build (see below for 'Imported code policy changed') == Camera support (+59, 1131 total) == Canon: PowerShot G5 X Mark II, G7 X Mark III, SX70 HS, EOS R, EOS RP, EOS 90D, EOS 250D, EOS M6 Mark II, EOS M50, EOS M200 EOS 1DX Mark III (lossless files only) DJI Mavic Air, Osmo Action FujiFilm GFX 100, X-A7, X-Pro3, X100V, X-T4 (uncompressed/lossless compressed only), X-T200 GoPro Fusion, HERO5, HERO6, HERO7, HERO8 Hasselblad L1D-20c, X1D II 50C Leica D-LUX7, Q-P, Q2, V-LUX5, C-Lux / CAM-DC25, SL2, M10 Monochrom Nikon D780, Z50, P950 Olympus TG-6, E-M5 Mark III, E-PL10, E-M1 Mark III, Panasonic DC-FZ1000 II, DC-G90, DC-S1, DC-S1R, DC-S1H, DC-TZ95 PhaseOne IQ4 150MP Ricoh GR III Sony A7R IV, A9 II, ILCE-6100, ILCE-6600, RX0 II, RX100 VII Zenit M also multiple smartphones (the tested ones are listed in LibRaw::cameraList) == Source code re-arranged == * dcraw.c is not used in the generation and build processes * dcraw_common.cpp and libraw_cxx.cpp are split into multiple code chunks placed in separate subfolders (decoders/ for raw data decoders, metadata/ for metadata parsers, etc) * dcraw_common.cpp and libraw_cxx.cpp remain to preserve existing build environments (these files are now just a bunch of #include directives). * It is possible to build LibRaw a)without postprocessing functions (dcraw_process() and called function) b)without postprocessing and LibRaw::raw2image() call (and called function). It may be useful to reduce library memory/code footprint. See Makefile.devel.nopp and Makefile.devel.noppr2i for the list of source files needed to build reduced/stripped library. == Normalized make/model == There is a huge number of identical cameras sold under different names, depending on the market (e.g. multiple Panasonic or Canon models) and even some identical cameras sold under different brands (Panasonic -> Leica, Sony -> Hasselblad). To reduce clutter, a normalization mechanism has been implemented in LibRaw: In imgdata.idata: char normalized_make[64]; - primary vendor name (e.g. Panasonic for Leica re-branded cameras) char normalized_model[64]; - primary camera model name unsigned maker_index; - primary vendor name in indexed form (enum LibRaw_cameramaker_index, LIBRAW_CAMERAMAKER_* constant). These fields are always filled upon LibRaw::open_file()/open_buffer() calls. const char* LibRaw::cameramakeridx2maker(int index): converts maker_index to normalized_make. We recommend that you use these normalized names in a variety of data tables (color profiles, etc.) to reduce the number of duplicate entries. New vendor index values will be added strictly to the end of the LibRaw_cameramaker_index table, ensuring that the numbers assigned to vendors that are already known to LibRaw will not change. == DNG frame selection == DNG frames selection code re-worked: - by default all frames w/ the NewSubfileType tag equal to 0 (high-res image) are added to the list of available images (selection performed via imgdata.params.shot_select field, as usual) - the special case for Fuju SuperCCD (SamplesPerPixel == 2) works as before: shot_select=1 will extract second sub-image. - Additional flags to imgdata.params.raw_processing_options: LIBRAW_PROCESSING_DNG_ADD_ENHANCED - will add Enhanced DNG frame (NewSubfileType == 16) to the list of available frames LIBRAW_PROCESSING_DNG_ADD_PREVIEWS - will add previews (NewSubfileType == 1) to the list. - By default, DNG frames are not reordered and are available in same order as in DNG (LibRaw traverses IFD/Sub-IFD trees in deep-first order). To prioritize the largest image, set LIBRAW_PROCESSING_DNG_PREFER_LARGEST_IMAGE bit in imgdata.params.raw_processing_options. - DNG Stage2/Stage3 processing via DNG SDK (request via flags in raw_processing_options) == Imported code policy disclaimer == We've changed the policy regarding 3rd party code imported into LibRaw. We (like other authors of open-source RAW parsers) gladly import support code for various RAW formats from other projects (if the license allows it). This is done to expand camera support. Unfortunately, not all imported code can tolerate truncated or otherwise damaged raw files, as well as arbitrary conditions or arbitrary data; not all authors handle rejecting unexpected input well. LibRaw is now widely used in various projects, including ImageMagick, which, in turn, is often used on web sites to process any input images, including arbitrary data from unknown users. This opens up wide possibilities for exploiting the various vulnerabilities present in the code borrowed from other projects into LibRaw. In order to avoid such security risks, - the borrowed code will no longer compile by default. We are not able to support it in general case, and the authors refuse to add code to reject unexpected input. Thus, if you use some kind of camera for which the support is disabled by default, you need to recompile LibRaw for your specific case. Formats currently affected: X3F (Foveon) file format. Code is imported from Kalpanika X3F tools: https://github.com/Kalpanika/x3f To turn the support on, define USE_X3FTOOLS Rapsberry Pi RAW+JPEG format. Code is imported from https://github.com/6by9/dcraw/, To turn the support on, define USE_6BY9RPI Format support is indicated via LibRaw::capabilities() call with flags: LIBRAW_CAPS_X3FTOOLS - Foveon support LIBRAW_CAPS_RPI6BY9 - RPi RAW+JPEG support == GoPro .gpr format support == GoPro format supported via open-source GPR SDK See README.GoPro.txt for details. == Windows support/Windows unicode (wchar_t*) filenames support == * (old) LibRaw's WIN32 external define split into 3 defines to fine tune compiler/api compatibility: LIBRAW_WIN32_DLLDEFS - use to compile DLLs (__dllimport/__dllexport attributes) LIBRAW_WIN32_UNICODEPATHS - indicates that runtime has calls/datatypes for wchar_t filenames LIBRAW_WIN32_CALLS - use Win32 calls where appropriative (binary mode for files, LibRaw_windows_datastream, _snprintf instead of snprintf, etc). If the (old) WIN32 macro is defined at compile time, all three new defines are defined in libraw.h If not, these defines are defined based on compiler version/libc++ defines * LibRaw::open_file(wchar_t*) is always compiled in under Windows, but if LIBRAW_WIN32_UNICODEPATHS (see above) is not defined, this call will return LIBRAW_NOT_IMPLEMENTED. Use (LibRaw::capabilities() & LIBRAW_CAPS_UNICODEPATHS) on runtime to check that this call was really implemented (or check for #ifdef LIBRAW_WIN32_UNICODEPATHS after #include <libraw.h>) == LibRaw*datastream simplified == * tempbuffer_open, subfile_open are not used, so removed from LibRaw_abstract_datastream and derived classes. * jpeg_src() call implemented using ->read() call and own buffering (16k buffer). * buffering_off() call added. It should be used in derived classes to switch from buffered reads to unbuffered. == minor/unsorted changes == * new flag LIBRAW_WARN_DNGSDK_PROCESSED to indicate decoder used * LibRaw::open() call, max_buf_size special meaning: == 1 => open using bigfile_datastream == 2 => open using file_datastream * Add support for zlib during configure * Fixed multiple problems found by OSS-Fuzz * Lots of changes in imgdata.makernotes (hope someone will document it) * DNG SDK could be used (if enabled) to unpack multi-image DNG files. * DNG whitelevel calculated via BitsPerSample if not set via tags. * DNG: support for LinearDNG w/ BlackLevelRepeat.. pattern * Generic Arri camera format replaced w/ list of specific camera models in supported cameras list. * new samples/rawtextdump sample: allows one to dump (small selection) of RAW data in text format. * samples/raw-identify: * +M/-M params (same as in dcraw_emu) * -L <file-w-filelist> parameter to get file list from a file * -m paramerer to use mmap'ed IO. * -t parameter for timing * samples/dcraw_emu: fixed +M handling * better support for Nikon Coolscan 16-bit NEF files. * Visual Studio project files: re-generated to .vcxproj (Visual Studio 2019), different intermediate folders for different sub-projects to allow 1-step rebuild. * imgdata.makernotes...cameraspecific: removed the vendor name prefix from variables. * Bayer images: ensure that even margins have the same COLOR() for both the active sensor area and the full sensor area. * raw processing flag bit LIBRAW_PROCESSING_CHECK_DNG_ILLUMINANT inverted and renamed to LIBRAW_PROCESSING_DONT_CHECK_DNG_ILLUMINANT. If not set, DNG illuminant will be checked. * New libraw_decoder_t flags: LIBRAW_DECODER_FLATDATA - in-file data could be used as is (if byte order matches), e.g. via mmap() LIBRAW_DECODER_FLAT_BG2_SWAPPED - special flag for Sony ARQ: indicates R-G-G2-B channel order in 4-color data * Camera-recorded image crop data is parsed into imgdata.sizes.raw_inset_crop structure: ctop,cleft,cwidth,cheight - crop size. aspect - LibRawImageAspects enum (3to2, 4to3, etc) * New define LIBRAW_NO_WINSOCK2 to not include winsock2.h on compile * New processing flag LIBRAW_PROCESSING_PROVIDE_NONSTANDARD_WB If set (default is not), and when applicable, color.cam_mul[] and color.WB_Coeffs/WBCT_Coeffs will contain WB settings for a non-standard workflow. Right now only Sony DSC-F828 is affected: camera-recorded white balance can't be directly applied to raw data because WB is for RGB, while raw data is RGBE. * New processing flag: LIBRAW_PROCESSING_CAMERAWB_FALLBACK_TO_DAYLIGHT If set (default is not), LibRaw::dcraw_process() will fallback to daylight WB (excluding some very specific cases like Canon D30). This is how LibRaw 0.19 (and older) works. If not set: LibRaw::dcraw_process() will fallback to calculated auto WB if camera WB is requested, but appropriate white balance was not found in metadata. * Google changes cherry-picked (thanks to Jamie Pinheiro) * speedup: ppg interpolate: const loop invariant * Bugs fixed -Fixed several UBs found by OSS Fuzz -Fixed several problems found by other fuzzers. - Thumbnail size range check (CVE-2020-15503) Thanks to Jennifer Gehrke of Recurity Labs GmbH for problem report. - fixed possible overflows in canon and sigma makernotes parsers - fixed possible buffer overrun in crx (cr3) decoder - fixed memory leak in crx decoder (if compiled with LIBRAW_NO_CR3_MEMPOOL) - fixed possible overrun in Sony SRF and SR2 metadata parsers * Fixed typo in longitude (member of parsed GPS structure), update required for code that uses it. 2019-03-05 Alex Tutubalin <lexa@lexa.ru> * Camera support Canon A560 (CHDK hack) FujiFilm X-T30 Nikon Coolpix A1000 Olympus E-M1X Sony ILCE-6400 Several dng files from phones and drones was tested and added to built-in camera list too. * Multiple names for same Panasonic cameras are processed via aliaces mechanics, no multiple duplicate fields in adobe_coeffs() table * Better makernotes parsing for many cameras * Better parsing of makernotes embedded into DNG files created by Adobe DNG Converter * New imgdata.params.raw_processing_options value: LIBRAW_PROCESSING_ZEROFILTERS_FOR_MONOCHROMETIFFS - If this bit is set - and TIFF file contains SamplesPerPixel == 1 - and filters value was not guessed from metadata parsing LibRaw will assume the file is monochrome, not bayer. This option is needed for monochrome scan processing (Imacon X1 etc). This option may broke old TIF-like RAW files processing (Kodak 760,etc) use with care (it is better to let user choose). 2018-12-12 Alex Tutubalin <lexa@lexa.ru> * Camera support: Canon: PowerShot A480 (CHDK hack), EOS 2000D, EOS 4000D Eyedeas E1 FujiFilm: GFX 50R, XF10, X-T3, X-T100, DBP680 GITUP G3 DUO (16:9 mode only, use custom camera for 4:3) Kodak PIXPRO AZ901 Leica M10-D, M10-P Nikon D3500, Z6, Z7, P1000 Panasonic LX100M2 Pentax K-1 II Sony A7 III, HX95, HX99, RX100-VA, RX100-VI * Fixed long standing bug in remove_zeroes: first two rows/cols was unprocessed * Better parsing for NEF files modified (damaged) by NikonTransfer * Better parsing for floating point DNG black levels (into color.dnglevels.fblack and dng_fcblack[], similar to color.black and color.cblack[] for other formats). * More flexible limit for RAW decoding memory usage: imgdata.params.max_raw_memory_mb (default is LIBRAW_MAX_ALLOC_MB_DEFAULT) * New flags for imgdata.params.raw_processing_options: LIBRAW_PROCESSING_CHECK_DNG_ILLUMINANT - will check DNG illuminant field when selecting color matrix (note: incompatibility with previous versions, so default is not set). LIBRAW_PROCESSING_DNGSDK_ZEROCOPY - will not copy data from Adobe DNG SDK decoded buffer, but use it as is * Switched from auto_ptr to unique_ptr, to get back define LIBRAW_USE_AUTOPTR * dcraw_emu: it is now possible to create output filename in a more flexible manner, via -Z switch: -Z - will output to stdout -Z ext will output into inputfilename.ext -Z .ext will output into inputfilename.inputext.ext 2018-11-22 Alex Tutubalin <lexa@lexa.ru> * Finally: got Sinar 4shot sample, works fine now * OpenMP critical sections for malloc/free; extra #ifdefs removed; bin/dcraw_dist could be built again using Makefile.devel * additional checks in parse_phase_one() * more checks on file offsets/tag len in parse_minolta * more checks in parse_ciff * Mempool check reworked * Old Leaf (16bit/3color/TIFF) support * Fix cameraWB->autoWB fallback * Polaroid x530 channel swap; get metadata pointer for Foveon files * Fixed Secunia Advisory SA86384 - possible infinite loop in unpacked_load_raw() - possible infinite loop in parse_rollei() - possible infinite loop in parse_sinar_ia() Credits: Laurent Delosieres, Secunia Research at Flexera * LibRaw 0.19.1-Release 2018-06-28 Alex Tutubalin <lexa@lexa.ru> * changed wrong fix for Canon D30 white balance * fixed possible stack overrun while reading zero-sized strings * fixed possible integer overflow * LibRaw 0.19.0-Release 2018-06-11 Alex Tutubalin <lexa@lexa.ru> * Sony uncompressed/untiled DNGs: do not set bits-per-sample to 14 bit * Do not change tiff_bps for DNG files * Another possible stack overflow in kodak radc reader * Secunia Advisory SA83507, credits Kasper Leigh Haabb, Secunia Research at Flexera" - parse_qt: possible integer overflow - reject broken/crafted NOKIARAW files * LibRaw 0.19-Beta6 2018-05-10 Alex Tutubalin <lexa@lexa.ru> * Put rogue printf's behind #ifdef DCRAW_VERBOSE * Exceptions was not caught in x3f_new_from_file resulting in x3f handle leak * packed_load_raw(): EOF check on each row * define LIBRAW_USE_CALLOC_INSTEAD_OF_MALLOC to use ::calloc instead of ::malloc in LibRaw_mem_mgr malloc calls; Note: realloc is not changed, so only partial fix * Fixed possible div by zero in EOS D30 WB data parse * U-suffix for filter-var manipulation consts * restored static specifier for utf2char() lost in previous bugfix * Fixed stack overrun in kodak_radc_load_raw * Secunia Advisory SA83050: possible infinite loop in parse_minolta() * LibRaw 0.19-Beta5 2018-05-03 Alex Tutubalin <lexa@lexa.ru> * CVE-2018-10529 fixed: out of bounds read in X3F parser * CVE-2018-10528 fixed: possible stack overrun in X3F parser * LibRaw 0.19-Beta4 2018-04-24 Alex Tutubalin <lexa@lexa.ru> * LibRaw 0.19-Beta3 * fixed lot of bugs reported by ImageMagic/oss-fuzz * fixed several bugs reported by Secunia team (adv 81800, Credit: Laurent Delosieres, Secunia Research at Flexera) 2018-03-22 Alex Tutubalin <lexa@lexa.ru> * LibRaw 0.19-Beta2 * Better handling of broken JPEG thumbnails * Panasonic GH5S/G9-hires decoder, thanks to Alexey Danilchenko Note: ABI has changed due to this patch, so shlib version increased * Fujifilm X-A5/A20 metadata parsing fix * New error code LIBRAW_TOO_BIG: image data size excess LIBRAW_MAX_ALLOC_MB * winsock2 included before windows.h to make MinGW happy 2018-02-23 Alex Tutubalin <lexa@lexa.ru> * LibRaw 0.19-Beta1 * 84 cameras added compared to 0.18 (1014 total): Apple iPhone 8(*), iPhone 8 plus, iPhone X BlackMagic URSA Mini 4k, URSA Mini 4.6k, URSA Mini Pro 4.6k Canon CHDK hack PowerShot A410, A540, D10, ELPH 130 IS, ELPH 160 IS, SD750, SX100 IS,SX130 IS, SX160 IS, SX510 HS, SX10 IS, IXUS 900Ti Canon PowerShot G1 X Mark III, G9 X Mark II, EOS 6D Mark II, EOS 77D, EOS 200D, EOS 800D, EOS M6, EOS M100 Casio EX-ZR4100/5100 DJI Phantom4 Pro/Pro+, Zenmuse X5, Zenmuse X5R FujiFilm S6500fd, GFX 50S, X100f, X-A3, X-A5, X-A10, X-A20, X-E3, X-H1, X-T20 GITUP GIT2P Hasselblad H6D-100c, A6D-100c Huawei P9 (EVA-L09/AL00), Honor6a, Honor9, Mate10 (BLA-L29) Leica CL, M10, TL2 LG V20 (F800K), VS995, Nikon D850, D5600, D7500, Coolpix B700 Olympus E-PL9, E-M10 Mark III, TG-5 OnePlus One, A3303, A5000 Panasonic DMC-FZ45, DMC-FZ72, DC-FZ80/82, DC-G9 (std. res mode only), DC-GF10/GF90, DC-GH5, DC-GX9, DC-GX800/850/GF9, DMC-LX1, DC-ZS70 (DC-TZ90/91/92, DC-T93), DC-TZ100/101/ZS100, DC-TZ200/ZS200 PARROT Bebop 2, Bebop Drone Pentax KP PhaseOne IQ3 100MP Trichromatic Samsung Galaxy Nexus, Galaxy S3, S6 (SM-G920F), S7, S7 Edge, S8 (SM-G950U), Sony A7R III, A9, DSC-RX0, DSC-RX10IV Yi M1 YUNEEC CGO3, CGO3P Xiaoyi YIAC3 (YI 4k) Note(*): for mobile phones with DNG format recording, only really tested cameras are added to supported camera list. Really LibRaw should support any correct DNG. * No more built-in support for LibRaw demosaic packs (GPL2/GPL3). We're unable to support this (very old code), so we'll be happy to transfer this code to some maintainer who wish to work with it. In LibRaw 0.19 we provide extension API: user-settable callbacks to be called in code points where demosaic pack code was called. - int callbacks.pre_identify_cb(void *) => to be called in LibRaw::open_datastream before call to (standard) identify() function. If this call returns 1, this means that RAW file is identified and all metadata fields are set, so no need to run standard identify code. - void callbacks.post_identify_cb(void*) => called just after identify(), but before any cleanup code; - dcraw_process() callbacks are called before dcraw_process phases (name speaks for itself): pre_subtractblack_cb, pre_scalecolors_cb, pre_preinterpolate_cb, pre_interpolate_cb, interpolate_bayer_cb, interpolate_xtrans_cb, post_interpolate_cb, pre_converttorgb_cb, post_converttorgb_cb All these new callbacks are called with (this) as the only arg. To continue LibRaw-demosaic-pack-GPLx support one need to subclass LibRaw, set needed callbacks in (e.g.) constructor code, than these callbacks to be called * Better DNG parser: - support for DefaultCrop Origin/Size tags (add LIBRAW_PROCESSING_USE_DNG_DEFAULT_CROP to raw_processing_options to enable) - better parsing for nested DNG tags (use tag from RAW IFD, fallback to IFD0 if no tag in current IFD) - DNG PreviewColorspace extracted into dng_levels.preview_colorspace * Metadata extraction: - Better extraction of camera measured balance (LIBRAW_WBI_Auto and WBI_Measured), this not the same as 'as shot' if some preset/manual tune is used. - Extraction of camera custom balances (LIBRAW_WBI_CustomN) - Nikon data compression tag extracted into makernotes.nikon.NEFCompression - Hasselblad BaseISO and Gain extracted into makernotes.hasselblad - Canon multishot params extracted into makernotes.canon.multishot - lot of other vendor-specific makernotes data (see data structures definitions for details). * New LibRaw::open_bayer call allows to pass sensor dump w/o metadata directly to LibRaw: virtual int open_bayer(unsigned char *data, unsigned datalen, ushort _raw_width, ushort _raw_height, ushort _left_margin, ushort _top_margin, ushort _right_margin, ushort _bottom_margin, unsigned char procflags, unsigned char bayer_pattern, unsigned unused_bits, unsigned otherflags, unsigned black_level); Parameters: data, datalen - buffer passed width/height/margins - speaks for itself procflags: for 10-bit format: 1: "4 pixels in 5 bytes" packing is used 0: "6 pixels in 8 bytes" packing is used for 16-bit format: 1: Big-endian data bayer_pattern: one of LIBRAW_OPENBAYER_RGGB,LIBRAW_OPENBAYER_BGGR, LIBRAW_OPENBAYER_GRBG,LIBRAW_OPENBAYER_GBRG unused_bits: count of upper zero bits otherflags: Bit 1 - filter (average neighbors) for pixels with values of zero Bits 2-4 - the orientation of the image (0=do not rotate, 3=180, 5=90CCW, 6=90CW) black_level: file black level (it also may be specified via imgdata.params) see samples/openbayer_sample.cpp for usage sample (note, this sample is 'sample only', suited for Kodak KAI-0340 sensor, you'll need change open_bayer() params for your data). * Color data added/updated/fixed for many cameras * Correct data maximum for Fuji X-* cameras * Thumbnail processing: - JPEG thumbnails: if compiled with libjpeg, color count is extracted into imgdata.thumbnail.tcolors - PPM (bitmap) thumbnails: color count is set according to thumbnail IFD tag - PPM16 thumbnails: if LIBRAW_PROCESSING_USE_PPM16_THUMBS set in raw_processing_options, than thumbnail will be extracted as is, not converted to 8 bit. thumbnail.tformat is set to LIBRAW_THUMBNAIL_BITMAP16 in this case. Untested, because it is hard to find RAWs with 16-bit bitmaps. == Compatibility fixes * struct tiff_tag renamed to libraw_tiff_tag * pow64f renamed to libraw_pow64f == Bugs fixed: * COLOR(r,c) works correctly on X-Trans files == Security fixes: Secunia #81000: Credit: Laurent Delosieres, Secunia Research at Flexera * leaf_hdr_load_raw: check for image pointer for demosaiced raw * NOKIARAW parser: check image dimensions readed from file * quicktake_100_load_raw: check width/height limits Secunia #79000: Credit: Laurent Delosieres, Secunia Research at Flexera * All legacy (RGB raw) image loaders checks for imgdata.image is not NULL * kodak_radc_load_raw: check image size before processing * legacy memory allocator: allocate max(widh,raw_width)*max(height,raw_height) Secunia #76000: * Fixed fuji_width handling if file is neither fuji nor DNG * Fixed xtrans interpolate for broken xtrans pattern * Fixed panasonic decoder * LibRaw 0.18.6 Other fixes: * Checks for width+left_margin/height+top_margin not larger than 64k * LIBRAW_MAX_ALLOC_MB define limits maximum image/raw_image allocation (default is 2048 so 2Gb per array) * LibRaw::read_shorts item count is now unsigned * Fixed possible out of bound access in Kodak 65000 loader * CVE-2017-14348: Fix for possible heap overrun in Canon makernotes parser Credit: Henri Salo from Nixu Corporation * Fix for CVE-2017-13735 * CVE-2017-14265: Additional check for X-Trans CFA pattern data * Fixed several errors (Secunia advisory SA75000) * ACES colorspace output option included in dcraw_emu help page * Avoided possible 32-bit overflows in Sony metadata parser * Phase One flat field code called even for half-size 2016-12-27 Alex Tutubalin <lexa@lexa.ru> * Licensing changes: - there is no 'LibRaw Software License 27032010' licensing anymore (and all signed agreements have expired) - LibRaw is now dual-licensed: LGPL 2.1 or CDDL 1.0 * Camera support (+87): Apple: iPad Pro, iPhone SE, iPhone 6s, iPhone 6 plus, iPhone 7, iPhone 7 plus BlackMagic Micro Cinema Camera, URSA, URSA Mini Canon PowerShot G5 X, PowerShot G7 X Mark II, PowerShot G9 X, IXUS 160 (CHDK hack), EOS 5D Mark IV, EOS 80D, EOS 1300D, EOS M10, EOS M5, EOS-1D X Mark II Casio EX-ZR4000/5000 DXO One, FujiFilm X-Pro2, X70, X-E2S, X-T2 Gione E7 GITUP GIT2 Google Pixel,Pixel XL Hasselblad X1D, True Zoom HTC MyTouch 4G, One (A9), One (M9), 10 Huawei P9 Leica M (Typ 262), M-D (Typ 262), S (Typ 007), SL (Typ 601), X-U (Typ 113), TL LG G3, G4 Meizy MX4 Nikon D5, D500, D3400 Olympus E-PL8, E-M10 Mark II, Pen F, SH-3, E-M1-II Panasonic DMC-G8/80/81/85, DMC-GX80/85, DMC-TZ80/81/85/ZS60, DMC-TZ100/101/ZS100,DMC-LX9/10/15, FZ2000/FZ2500 Pentax K-1, K-3 II, K-70 PhaseOne IQ3 100MP RaspberryPi Camera, Camera V2 Ricoh GR II Samsung Galaxy S7, S7 Edge Sigma sd Quattro Sony A7S II, ILCA-68 (A68),ILCE-6300,DSC-RX1R II,DSC-RX10III, DSC-RX100V,ILCA-99M2 (A99-II), a6500 IMX214, IMX219, IMX230, IMX298-mipi 16mp, IMX219-mipi 8mp, Xperia L PtGrey GRAS-50S5C YUNEEC CGO4 Xiaomi MI3, RedMi Note3 Pro * Floating point DNG support: - new data fields: imgdata.rawdata.float_image - bayer float data imgdata.rawdata.float3_image - 3-component float data imgdata.rawdata.float4_image - 4-component float data imgdata.color.fmaximum - float data maximum (calculated from real data, rounded to 1.0 if below 1.0) - new raw processing flag LIBRAW_PROCESSING_CONVERTFLOAT_TO_INT - converts float data to 16-bit integer immediately after decoding with default parameters - new API Calls: int LibRaw::is_floating_point() returns non-zero if RAW file contains floating point data int LibRaw::have_fpdata() returns non-zero if rawdata.float*_image is not null (so FP data has been unpacked but not converted to integrer, see below). LibRaw::convertFloatToInt(float dmin=4096.f, float dmax=32767.f, float dtarget = 16383.f) converts float/float3/float4_image to raw_image/color3/color4_image with or without scaling: - if both real data maximum and metadata maximum are within the range ( >= dmin && <=dmax), float data is just converted to integer - if data is out of the range given above, values are scaled so real data maximum becomes dtarget - if data was rescaled (normalized), scale multiplier is stored in imgdata.color.fnorm * LibRaw can be built with Adobe DNG SDK support to decode exotic DNG formats (e.g. 8 bit). See README.DNGSDK.txt for details * New API calls unsigned LibRaw::capabilities and C-API libraw_capabilities() allows developers to determine LibRaw compile flags at runtime. Returns ORed bit fields: LIBRAW_CAPS_RAWSPEED - LibRaw was compiled with RawSpeed Support LIBRAW_CAPS_DNGSDK - LibRaw was compiled with Adobe DNG SDK LIBRAW_CAPS_DEMOSAICSGPL2, LIBRAW_CAPS_DEMOSAICSGPL3 - LibRaw was compiled with demosaic packs (GPL2/GPL3) * More metadata parsed: - White balance coefficients stored in the raw file are extracted into: int imgdata.color.WBCoeffs[256][4] - array indexed by EXIF lightsource type for example, WBCoeffs[21][..] contains coefficients for D65 lightsource float imgdata.color.WBCT_Coeffs[64][5] contains white balance data specified for given color temperature: WBCT_Coeffs[i][0] contains temperature value, and [1]..[4] are WB coefficients. - DNG analog balance, per-channel black/white level, and forward matrix - vendor specific metadata stored in vendor-specific data structures * new C-API calls: void libraw_set_user_mul(libraw_data_t *lr,int index, float val); void libraw_set_ca_correction(libraw_data_t *lr,int ca_correc, float ca_red, float ca_blue); void libraw_set_cfalinenoise(libraw_data_t *lr,int cfaline, float linenoise); void libraw_set_wf_debanding(libraw_data_t *lr, int wf_debanding, float wfd0, float wfd1, float wfd2, float wfd3); void libraw_set_interpolation_passes(libraw_data_t *lr,int passes); * Existing API changes: imgdata.params fields (all very specific purpose): sony_arw2_options, sraw_ycc, and params.x3f_flags replaced with single bit-field raw_processing_options See LIBRAW_PROCESSING_* bits in documentation. * zlib library is optional Use -DUSE_ZLIB to compile with zlib (to provide deflate DNG support) * libjpeg version: jpeg_mem_src() is mandatory, so use libjpeg-turbo or libjpeg 8+ * Fixes in vng_interpolate to make modern compilers happy * Fixed bug in Sony SR2 files black level * DNG files with BlackLevel both in vendor makernotes and BlackLevel: BlackLevel tag always takes precedence * strlen replaced with strnlen in most cases, added local version of strnlen * ChannelBlackLevel added to canon makernotes * unpack_thumb() data size/offset check against file size 2015-08-15 Alex Tutubalin <lexa@lexa.ru> * LibRaw 0.17 * Fixed dcraw.c ljpeg_start possibly buffer overrun * fixed several bugs detected by using American Fuzzy Lop * C-API extension to support 3DLut Creator * More metadata parsing/extraction: - XMP packet extracted (if exists) - DNG Color information parsed - GPS data (partially) parsed - EXIF/Makernotes parsed for used optics (for both RAW files and DNG converted by Adobe convertor). * Exif/Makernotes parser callback (called for each processed tag) * Sony ARW2.3 decoder: - params.sony_arw2_hack removed, decoded data are always in 0...17k range (note the difference with dcraw!) - Additional processing options for Sony lossy compression technical analysis. * Dcraw 9.26 imported (but some changes not approved because Libraw do it better) with some exceptions: - no Pentax K3-II frame selection code - no built-in JPEG decompressor * Many improvements in data decoding/processing: - Correct decoding of black level values from metadata for many formats, LibRaw do not rely on hardcoded black levels. * 224 camera models added to supported camera list.

Set it to 3 if you want to force use of DNG embedded matrix. - Tone curve for Canon RMF format supported - Color data for Canon C500 * Additional camera support: Alcatel 5035D DJI 4384x3288 Fujifilm F900EXR Kodak 12MP Matrix 4608x3288 Nokia 1200x1600 Olympus E-PL6 Panasonic DMC-FZ7 2014-01-17 Alex Tutubalin <lexa@lexa.ru> * Camera support: Added: Fujifilm XE2, XQ1 Color data updated: Nikon D4 1 AW1/J3, Fuji X-M2 Fixes: Nikon D610 visible image area, Canon A3300 bayer pattern * RawSpeed support: enabled processing for cameras, unknown to RawSpeed * Fixed error in LibRaw::unpack_thumb() * little improve performance in my_strcasestr * Fix compiler errors for VS2012/OpenMP * Fixed typo which prevents to use Demosaic Pack GPL2 * LibRaw 0.16.0-Release 2013-11-15 Alex Tutubalin <lexa@lexa.ru> * New cameras supported Leica C, X VARIO Nikon D5300, D610, Df, 1 AW1 Nokia Lumia 1020, 1520 Olympus STYLUS1 Pentax K-3 Sony RX10, A3000 (ILCE-3000), * Color data updated: Canon S120 Nikon P7800, 1 J3 Olympus E-M1 * Corrected image visible area sizes Canon G16 Sigma pre-Merrill cameras: small and medium-sized RAWs * Better EXIF parsing: - ISO values for new Nikon cameras (D4, D800) - black level extraction for Nikon D5300 - correct Olympus color data conversion * Better Visual Studio compatibility (esp. old versions) * Cmake build: added ws2_32 library for MinGW builds * LibRaw 0.16.0-Beta1 2013-10-22 Alex Tutubalin <lexa@lexa.ru> * Support for new cameras: Sony A7, A7R Panasonic GM1 * Sony RX1R and RX100M2 color data updated. * Sony cameras model name is set by SonyModelID EXIF tag * Sony ARW2: black level and color matrix extracted from EXIF data * Samsung: black level and color matrix extracted from EXIF; Camera multipliers are now extracted correctly even if black is not 0 * Better source compatibility with Mac OS X compilation * Better source compatibility with Win32 compilation * DNG without Compression tag assumed uncompressed * Better X3F-tools based Foveon support: - new Foveon metadata parser based on X3F-tools. So, if LibRaw compiled without demosaic-pack-GPL2, then no dcraw Foveon code used. - Support for Medium resolution RAWs from DPx Merrill and SD1 cameras. RAW data extracted as is (4800x1600 pixels), aspect ratio is set to 0.5, so these RAWs are processed to full-size 4800x3200 RGB. - Support for Foveon thumbnail extraction. Only JPEG and bitmap thumbnails extracted, but 'foveon' (RAW) thumbnails are really not used in production cameras. - New imgdata.params.force_foveon_x3f flag Forces use of x3f-tools based code for Foveon processing if LibRaw compiled with demosaic-pack-GPL2 (and does nothing if LibRaw compiled without this pack). New flag -disadcf added to dcraw_emu sample to use this flag. - LibRaw do not calls exit() on broken Foveon files. * API/ABI changed, so all code using LibRaw should be recompiled. * LibRaw 0.16.0-Alpha3 2013-10-16 Alex Tutubalin <lexa@lexa.ru> * Support for new cameras: Canon S120 (preliminary color data), G16 Fujifilm X-A1 (preliminary color data) Hasselblad Lunar, Stellar Nikon P7800 (preliminary color data) Pentax K50, K500, Q7 Samsung Galaxy NX (EK-GN120) Sony NEX-5T * Updated color data for: Samsung NX300 Sony RX1R Sigma SD1, SD1 Merrill, DPxx (only if non-GPL2 foveon decoder used) * Image dimensions table for Foveon cameras (only if non-GPL2 foveon decoder used) * Fixed memory leak in x3f-tools code (new Foveon decoder) * Fixed DHT-demosaic incompatibility with MS VisualStudio in OpenMP directives * Additional image size checks. * LibRaw 0.16-Alpha2 2013-09-22 Alex Tutubalin <lexa@lexa.ru> * Support for new cameras: Baumer TXG14 Blackmagic Cinema Canon EOS 70D, C500 Fujifilm X-M1 Nikon D5200 Olympus E-P5,E-M1 OmniVision OV5647 (Raspberry Pi) Panasonic LF1, GX7, GF6 Richon GR Samsung NX300, NX1100, NX2000 Sony RX100II, RX1R, NEX-3N * Support for Foveon sensor based on X3F code by Roland Karlsson BSD-like license, so included in main LibRaw code. No 'foveon interpolation', so no way to get good colors from old Sigma cameras (SD9, SD14, Polaroid x530). For modern Foveon cameras one may try to create ICC profile (not supplied). TODO: thumbnail extraction, fast cancellation Old foveon_*_load_raw (from dcraw) code is used if compiled with LIBRAW_DEMOSAIC_PACK_GPL2 * API Changes: + New parameters in imgdata.params: - imgdata.params.no_interpolation - disables interpolation step in LibRaw::dcraw_process() call. - imgdata.params.no_auto_scale - disables call to scale_colors() in LibRaw::dcraw_process() call. - imgdata.params.sraw_ycc - disables Canon sRAW YCbCr to RGB conversion in LibRaw::unpack() call (use for RAW analyzers + New Fuji X-Trans handling: - imgdata.iparams.filters value is now 9 for Fuji X-Trans (instead of 2) - imgdata.iparams.xtrans[6][6] matrix contains row/col to color mapping for Fuji X-Trans sensor. + LibRaw::setCancelFlag() - use for fast decoder termination + LibRaw_abstract_datastream::make_byte_buffer() call is not needed more. + New demosaic code: DHT Demosaic by Anton Petrusevich Set params.user_qual=11 to use. + New demosaic code: Modified AHD Demosaic by Anton Petrusevich Set params.user_qual=12 to use. + New C-API call libraw_COLOR(libraw_data_t *t, int row,int col) (so LibRaw::COLOR(row,col) exposed to C-API users) * Removed faster lossless jpeg decoder ported from RawSpeed library some years ago. Build LibRaw with RawSpeed to get fast decoding. * Fixed decoding error for some Canon sRAW files. * Disabled RawSpeed's bad pixel processing if RawSpeed used. * EOS M and EOS 70D added to unique Canon ID table * Canon EOS model name normalized by unique ID table * Backported 0.15.4 input data checks * Support for CMake builds * Updated RawSpeed supported camera list * Internals changed, so all code using LibRaw should be recompiled. * LibRaw 0.16.0-Alpha1 2013-05-23 Alex Tutubalin <lexa@lexa.ru> LibRaw 0.15-Release New camera/format support: * Adobe DNG: fast Load DNG (LightRoom 4.x), support for lossy-compressed DNG (LR 4.x, requires libjpeg 6+) * Canon: G1 X, SX220 HS, EOS 5D Mark III, EOS 650D, EOS 1D-X, 100D (Rebel SL1), 700D (Rebel T5i), 6D, EOS M, G15, S110, SX50 * Casio: EX-ZR100,EX-Z8 * Fujifilm: X-S1, HS30EXR, X1-Pro,X-E1, X20, X100S, SL1000, HS50EXR, F800EXR, XF1 * Leica: D-LUX6 and V-LUX4 * Nikon: D4, D3200, D800, D800E, 1 J2, 1 V2, D600, 1 J3, 1 S1, Coolpix A, Coolpix P330, Coolpix P7700, D7100 * Olympus: E-M5, XZ-2, XZ-10, E-PL5, E-PM2 * Panasonic: G5, G6, DMC-GF5, FZ200, GH3, LX7 * Pentax: MX-1, K-5 II, K-5 IIs, K-30, Q10 * Samsung: EX2F, NX20, NX210, support for the new firmware for NX100 * Sigma: SD15, SD1, SD1 Merill, DP1, DP1S, DP1X, DP2, DP2S, DP2X (only with Demosaic-pack-GPL2) * Sony: SLT-A58, RX-1, SLT-A99, NEX-5R, NEX-6, NEX-F3, SLT-A37, SLT-A57 * Multishot files: Imacon Ixpress 39Mpix API changes: 1. dcraw_process() can now be called several times with different parameters without re-opening and unpacking the file for second and consecutive calls to dcraw_process 2. deleted (nobody uses those) - LibRaw::dcraw_document_mode_processing (and respective C-API) - imgdata.color.color_flags data field 3. LibRaw::unpack() now decodes data into different buffers, the buffer depends on the raw data type - imgdata.rawdata.raw_image - 1 color component per pixel, for b/w and Bayer type sensors - imgdata.rawdata.color3_image - 3 color components per pixel, sRAW/mRAW files, RawSpeed decoding - imgdata.rawdata.color4_image - 4 components per pixel, the 4th component can be void 4.

To enable this support you should: + install libjasper JPEG2000 support library + compile LibRaw with -DUSE_JASPER compiler switch (./configure will do it for you) + If you use own LibRaw_datastream implementation, you should implement make_jas_stream() call for your datastream. See bottom of src/libraw_cxx.cpp for implementations in datafile and mem-buffer LibRaw streams. * Bugfix: green matching is turned off if output image is shrinked due to wavelet filtering or aberration correction. * fixed open_file()/adjust_sizes_info_only() code path * Removed imgdata.sizes.bottom_margin and right_margin data fields use imgdata.sizes.raw_width - width - left_margin to get right one, the same with bottom_margin. * minor ./configure cleanup * Qmake files and Visual Studio Project files are updated. * New version check macros: For use at runtime checks: LIBRAW_RUNTIME_CHECK_VERSION_EXACT() - checks that runtime major/minor version numbers are same with compile-time values. LIBRAW_RUNTIME_CHECK_VERSION_NOTLESS() - checks that runtime version is not less that compile-time one. For use at compile-time in preprocessor directives: LIBRAW_COMPILE_CHECK_VERSION_EXACT(major,minor) - Compile-time check that LibRaw version is exact major.minor. LIBRAW_COMPILE_CHECK_VERSION_NOTLESS(major,minor) - Compile-time check that version is not less than major.minor. * all client code should be recompiled due to internals change. * LibRaw 0.14.0-Alpha4 2011-07-19 Alex Tutubalin <lexa@lexa.ru> * New sample samples/postprocessing_benchmark.cpp This sample measures postprocessing speed. All demosaic methods, averaged white balance, median filtering, wavelet filtration, highlight recovery, and cropping are supported. * Removed LibRaw::rotate_fuji_raw() call and corresponding C-API call. * The LibRaw::adjust_sizes_info_only() call may be called repeated and mixed with dcraw_process() call. * Postprocessing speedup and optimization, especially if cropping set. * Cropping works for FujiCCD raws. For the technical reasons, the position of top-left corner of crop area will be rounded to the nearest multiple of 4 (the corner is shifted top-left). * LibRaw 0.14.0-Alpha3 2011-07-15 Alex Tutubalin <lexa@lexa.ru> * imported cropping code from 0.13 branch 2011-07-12 Alex Tutubalin <lexa@lexa.ru> * samples/multirender_test - check for different clip settings 2011-07-11 Alex Tutubalin <lexa@lexa.ru> * New call LibRaw::free_image(), deallocates imgdata.image buffer. Use this call if current postprocessing results are not needed, but it is to early to call recycle() because dcraw_process() may be called later. * New C-API calls libraw_raw2image() - C API for LibRaw::raw2image() libraw_free_image() - C API for LibRaw::free_image() libraw_get_decoder_info() - C API for LibRaw::get_decoder_info() * Bugfix: change of params.user_flip aftee open()/unpack() calls should work. * LibRaw 0.14.0-Alpha2 2011-07-10 Alex Tutubalin <lexa@lexa.ru> * Multiple rendering (LibRaw::dcraw_process() calls) allowed without re-opening RAW file thrfough the sequence of open()/unpack() calls. You should be able to change any processing parameters (except shot_select parameter) between dcraw_process() calls. + New sample in samples/multirender_test.cpp: renders data 4 times: in half and full modes with different white balance settings. + Unprocessed RAW data is stored in separate data buffer: (2 bytes per pixel for all Bayer-pattern images, 8 bytes per pixel for Foveon, sRAW, and other full-color raw formats), so now LibRaw uses 25% more memory for full processing of most common Bayer images; while for just unpack memory is reduced 4 times. + New call LibRaw::raw2image() fills imgdata.image array with fresh copy of data. There is no need to call raw2image() separately if you use dcraw_process() or dcraw_document_mode_processing() calls. + New call LibRaw::get_decoder_info() to determine raw data storage layout. See samples/unprocessed_raw.cpp for an example of how to use it. If your code uses usual open()/unpack()/dcraw_process() call sequence, then NOTHING CHANGED: your program should produce same results. For interactive programs you may skip open()/unpack() calls after adjusting processing parameters, so user should see image refreshed much faster. If your code uses raw data (open+unpack calls), you need to call LibRaw::raw2image(), and imgdata.image will contain same bitmap as in LibRaw 0.13.x If you code uses access to masked borders data, you need to rewrite it. See samples/unprocessed_raw.cpp as a sample. Unfortunately, documentation is untouched yet. This problem will be fixed in next Alpha release. Other changes: * No separate imgdata.masked_pixels buffers, Bayer raw formats are read to buffer with borders. So, no ugly add_masked_border_to_bitmap() call. * No filtering_mode parameter.

All other parameters change will be implemented later. * LibRaw 0.12-alpha1 2010-11-11 Alex Tutubalin <lexa@lexa.ru> * Imported 0.11(2) version changes: + Fixed dcraw_emu command line processing code + OpenMP is completely disabled on MacOS X if compiled with -pthread due to well-known MacOS problem. + dcraw 9.05 (1.439) imported, many new cameras supported: Canon: G12, SX120, 60D, Hasselblad H4D, Nokia X2, Olympus E-5, Nikon: D3100, D7000, P7000, Panasonic: FZ40, FZ100, LX5, Pentax: K-r, K-5, 645D, Samsung GX20, WB2000 * LibRaw 0.12-alpha0 2010-11-08 Alex Tutubalin <lexa@lexa.ru> * Fixes for Sun Studio compiler compatibility * Fixes for Visual Studio 2010 compatibility * All russian-language files are converted to UTF-8 * LibRaw 0.11.0-Release 2010-10-18 Alex Tutubalin <lexa@lexa.ru> * Disabled OpenMP for wavelet_denoise under Mac OS X * More Visual C++ 2003 warnings cleaned in libraw/*h files * LibRaw 0.11-Beta7 2010-10-16 Alex Tutubalin <lexa@lexa.ru> * internal/dcraw_fileio.c can be compiled with -DDCRAW_VERBOSE again * fixed comment style in libraw_datastream.h * LibRaw 0.11-Beta6 2010-10-15 Alex Tutubalin <lexa@lexa.ru> * New changes to I/O layer. Three LibRaw_*datastream clasees are exists: + LibRaw_buffer_datastream - buffer reaging + LibRaw_file_datastream - file reading using iostreams (large files are no supported on some systems) + LibRaw_bigfile_datastream - FILE*-based file I/O * file/bigfile_datastream is selected automatically by LibRaw::open_file based on input file size. By default, files larger than 250Mb are opened using bigfile interface, you may change this behaviour by using second optional parameter of open_file() * There is no way to use default parameter values in C API, so new call libraw_open_file_ex added with two parameters (file name and minimal file size for bigfile_datastream use). * all client code should be recompiled due to internals change. * All LibRaw_abstract_datastream functions are virtual again. You may (again) use your own I/O layer. * new -d key for dcraw_emu sample: print timings of processing stages * simple_dcraw sample simplified: no mmap code * LibRaw 0.11-Beta5 2010-10-08 Alex Tutubalin <lexa@lexa.ru> * Fixed bug in exception handling in OpenMP sections in AHD interpolation code. * LibRaw_datastreams are now C++ iostreams based instead of old plain FILE* calls. LibRaw::open_file() in multithreaded programs are WAY faster on many OSes (Linux, Windows, MacOSX) because of no extra locks. * all client code should be recompiled due to internals change. * LibRaw 0.11-Beta4 2010-10-01 Alex Tutubalin <lexa@lexa.ru> * Fixed bug in LibRaw::dcraw_process() code: for half_size processing, params.four_color_rgb was set to 1 internally and not returned back after postprocessing. * Several Visual Studio 2003 compatibility fixes * AHD interpolation refactored. Now it is about 10% faster than dcraw in single-process mode and up to 1.5 times faster on 4-core and OpenMP (total execution time counted, not AHD itself) Thanks to Adam Hooper * AHD interpolation refactored. Now it is about 10% faster than dcraw in single-process mode and up to 1.5 times faster on 4-core and OpenMP (total execution time counted, not AHD itself) Thanks to Adam Hooper * LibRaw 0.11-Beta3 2010-09-07 Alex Tutubalin <lexa@lexa.ru> * Phase One files: LibRaw::unpack() sets colordata.black to approximately correct value. * Fixed minor error in setting colordata.maximum value for Phase One files. * LibRaw::subtract_black() sets colordata.black and colordata.cblack[] to zero to preserve data integrity. * LibRaw 0.11-Beta2 2010-09-04 Alex Tutubalin <lexa@lexa.ru> * It is now possible to crop output image on postprocessing stage (dcraw_process). Coordinates and size of the output box are set via imgdata.params.cropbox[4] parameter. Look into LibRaw documentation for more details. + New fatal error code LIBRAW_BAD_CROP + New dcraw_emu sample command line switch: -B x y w h (sets cropbox) Thanks to Patrick and Jan. * Processing pipeline has changed: the black level is subtracted from data on postprocessing stage either automatically (on dcraw_process() stage) or by special LibRaw API call: + New API calls: LibRaw::subtract_black() (C++ API) and libraw_subtract_black (C API). If you use dcraw_process() or dcraw_document_mode_processing() calls YOU DON'T NEED to call subtract_black() directly. + The raw preprocessing mode LIBRAW_FILTERING_NOBLACKS is deprecated and removed from LibRaw. * New ./configure script. Use ./configure -h for usage details. Thanks to Siddhesh Poyarekar * New API cals static LibRaw::dcraw_clear_mem() (C++ API) and libraw_dcraw_clear_mem(..) (C API). This calls are used to free memory, allocated by dcraw_make_mem_image() and dcraw_make_mem_thumb() instead of free() call. In some cases LibRaw and calling process have different memory managers, so free() of make_mem_image() data results to program crash (especially in Win32/VisualStudio environment). * LibRaw::free() is now private instead of public (again). * Minor changes and bugfixes: + Memory allocation exceptions (std::bad_alloc) are caught, so LibRaw API calls will return reasonable error codes instead of C++ exception (possibly unhandled). This problem is very unlikely to see in wild: if application cannot allocate small data for internal structure, it will always fail on allocation for RAW image data. + WIN32/VisualStudio 2008/2010: fopen,fscanf and sscanf calls in Libraw_datastream code are changed to *_s (secure) ones. + Debug print removed from fatal error handler. + Mmaped I/O for dcraw_emu sample is turned on via -E switch now (because old -B switch is used for setting cropbox). * all client code should be recompiled due to structures size change * LibRaw 0.11-Beta1 2010-07-31 Alex Tutubalin <lexa@lexa.ru> * dcraw 9.04 (1.438) imported: changes in tiff metadata parser, fixed a typo in Canon A720 model name * small patch in Sony ARW2 unpacking code to make valgrind happy * LibRaw 0.10.0-Beta3. 2010-07-05 Alex Tutubalin <lexa@lexa.ru> * dcraw 9.03 (1.437) imported: + New cameras: Canon SX20, Nikon D3s, Olympus E-P2, Panasoni DMC-GF1, Samsung EX1, Sony A450 + Color data changed for some cameras * LibRaw 0.10.0-Beta2. 2010-06-06 Alex Tutubalin <lexa@lexa.ru> * dcraw 9.01 (1.434) imported: + Separate black levels for each color channel. + New cameras: Canon 550D, Casio EX-Z1050, Fuji HS10/HS11, Kodak Z981, Panasonic G2 and G10, Phase One P65, Samsung NX-10 and WB550, Sony NEX-3 and NEX-5. + Fixed file descriptor leak in dark frame subtraction processing * Fixed dcraw 9.01's bug in DNG black level processing * Preliminary support for Sony A450 camera. * New command-line switch -h in mem_image sample (half_size support) * Some patches by Johannes Hanika (darktable author): + OpenMP speedup for PPG-interpolation + green_matching - suppress of 'color maze' on cameras with different green channel sensitivity. This option is turns on by filed with same name in imgdata.params * all client code should be recompiled due to structures size change * LibRaw::free() is now public instead of private. * LibRaw 0.10.0-Beta1. 2010-05-15 Alex Tutubalin <lexa@lexa.ru> * Fixed bug in 8-bit RAW processing code * LibRaw 0.9.1-Release 2010-04-26 Alex Tutubalin <lexa@lexa.ru> * OpenMP support: OpenMP is possible under MinGW (untested) * LibRaw 0.9.0-Release 2010-04-21 Alex Tutubalin <lexa@lexa.ru> * Finally fixed inconsistency in Fuji files processing * New COLOR(row,col) call to get bayer color index in image[] array * Old FC() call is deprecated and will be removed in future releases * unprocessed_raw sample switched to COLOR() call * LibRaw 0.9.0-Beta5 2010-04-10 Alex Tutubalin <lexa@lexa.ru> * Fixed bug in unpacking DNG files made from Fuji RAFs. * LibRaw 0.9.0-Beta4 2010-04-09 Alex Tutubalin <lexa@lexa.ru> * Fixed typecast error (problem reported only on gcc 4.2.1/32bit) in CRW files processing. * C++ API call LibRaw::adjust_maximum() is now deprecated and de-documented, use params.adjust_maximum_thr instead (on by default) * C-API call libraw_adjust_maximum() removed. * New postprocessing parameter params.adjust_maximum_thr This parameter replaces LibRaw::adjust_maximum(), but more flexible Defaults are reasonable (0.75, same as in old adjust_maximum), look into documentation for more details. * Removed last OpenMP warning * dcraw_emu's -c parameter now wants numeric (float) argument. This value is assigned to params.adjust_maximum_thr. Use -c 0.0 for dcraw compatibility. * all client code should be recompiled due to structures size change * LibRaw 0.9.0-Beta3 2010-03-29 Alex Tutubalin <lexa@lexa.ru> * Fixed a bug in channel_maximum[] calculation for Panasonic cameras. * channel_maximum[] data now calculated for ALL cameras. * OpenMP warnings suppressed. * Documented the -c command-line switch for dcraw_emu sample. * Removed extra messages from dcraw_emu sample. * LibRaw 0.9.0-Beta2 2010-03-28 Alex Tutubalin <lexa@lexa.ru> New licensing: * Triple licensing (selected by LibRaw user): + LGPL 2.1 (http://www.gnu.org/licenses/lgpl-2.1.html) + CDDL 1.0 (http://www.opensource.org/licenses/cddl1.txt) + LibRaw Software License (27 March 2010 version) (http://www.libraw.org/data/LICENSE.LibRaw.pdf) * There is no separate LibRaw-Lite and LibRaw-Commercial versions, only single LibRaw. Current LibRaw-Lite and LibRaw-Commercial users should switch to LibRaw without loss of functionality. It is possible to change licensig too (e.g. from LGPL to CDDL for LibRaw-Lite users and from LibRaw License to LGPL or CDDL for LibRaw-Commercial users). * No Foveon support :( It is not possible to get good color from Foveon sensors with *any* converter. So, there is no need to support these cameras. Dcraw's Foveon-processing code is too strict licensed (GPL), so we choose to drop it. New Features: * New data field colordata.channel_maximum[4] - per channel data maximum (calculated for most cameras, 0 for others). * New call LibRaw::adjust_maximum() (and libraw_adjust_maximum() in C API). This call changes hardcoded colordata.maximum value to calculated at unpack stage. This helps suppress false color in highlights (magenta clouds and so). * New command line parameter -c for dcraw_emu sample. Calls adjust_maximum() for each processed file. * all client code should be recompiled due to structures size change * LibRaw 0.9.0-Beta1 2010-02-06 Alex Tutubalin <lexa@lexa.ru> * Fixed ambiguity in pow/sqrt calls (to make Sun C++ compiler happy) * OpenMP is not supported under MS Visual Studio * Masked a bug in RIFF format parser * LibRaw 0.8.6 2009-12-30 Alex Tutubalin <lexa@lexa.ru> * Fixed bug in simple_dcraw sample parameters processing * Imported dcraw 8.99 (1.432): + New cameras: Canon: 1D mk IV, Canon S90; Casio Z750, Nikon D3S, Pentax K-x, Sony A-500/550, Fuji S200EXR + New color data for Canon G11 and Sony A850 + Changes in Canon sRAW processing + Changes in Kodak metadata processing + Changes in uncompressed Fuji files processing (FinePix S5xxx) * LibRaw 0.8.5 2009-11-21 Alex Tutubalin <lexa@lexa.ru> + Fixed a bug in processing of uncompressed Phase One files * LibRaw 0.8.4 2009-10-24 Alex Tutubalin <lexa@lexa.ru> + Imported dcraw 8.98/1.431: * New Cameras: Canon 7D, Panasonic GF1, Sony A850 and A380, Casio Z850, Nikon D300s + changes in libraw_datastream.h to make compilers more happy * LibRaw 0.8.3 2009-09-02 Alex Tutubalin <lexa@lexa.ru> + Fixed bug in Hasselblad .3FR unpacking code * Imported dcraw 8.97/1.428: Nikon D3000 image width fix * LibRaw 0.8.2 2009-08-31 Alex Tutubalin <lexa@lexa.ru> + Enum LibRaw_thumbnail_formats (LIBRAW_IMAGE_*) values changed to match values in enum LibRaw_image_formats (LIBRAW_THUMBNAIL_*).

This call used in sample application dcraw_emu and simple_dcraw (with -B command-line switch) to test new API. * Error handling callback functions now can be called with NULL filename passed (if underlying data stream object does not know file name). So, client error handling callbacks should work with NULL filename. * All client code should be recompiled * Imported dcraw 8.90/1.417: + Support for loading White Balance data from Sony ARW files edited with Sony IDC software. * LibRaw 0.7.0-Alpha5 2009-01-17 Alex Tutubalin <lexa@lexa.ru> * Raw filtering mode LIBRAW_FILTERING_NOPOSTPROCESS has renamed to LIBRAW_FILTERING_NORAWCURVE for better reflect its purpose. This filtering_mode bit turns off tone curve applying on RAW data on bayer-pattern cameras with raw tone curve: + Adobe DNG (only RAW with bayer pattern) + Nikon compressed NEF + Some Kodak cameras + Sony A700/A900 (tone curve applied to 8-bit raws) * unprocessed_raw sample: added command-line key -N, this key turns on LIBRAW_FILTERING_NORAWCURVE filtering mode. * New scheme of Fuji RAW processing (introduced in 0.7-Alpha3) supports DNG files generated from Fuji RAF. * Imported dcraw 8.90/1.416: + better support for Samsung S85 + fixed possible integer overflow in wavelet denoising code * LibRaw 0.7.0-Alpha4 2009-01-14 Alex Tutubalin <lexa@lexa.ru> * Black mask extraction supported for all files with bayer data (one component per pixel). Black mask data not available for multi-component data (Foveon, Canon sRAW, Sinar 4-shot, Kodak YCC/YRGB). * Black level subtraction can be turned off for all bayer cameras (added support for PhaseOne backs). * Fujifilm camera processing model changed: + RAW data is extracted without 45-degree rotation + dcraw-compatible rotation is performed on postptocessing stage + it is possible to rotate RAW data without postprocessing by LibRaw::rotate_fuji_raw() call. * New filtering mode setting: LIBRAW_FILTERING_NOPOSTPROCESS This bits turns off RAW tone curve processing based on tone curve readed from RAW metadata. This mode supported only for PhaseOne backs now (to be supported on all relevant cameras in nearest future releases) * Black level data (got from RAW data) are stored for PhaseOne backs. * Black level subtraction bug (derived from dcraw) fixed for PhaseOne files. * Fixed processing of -s parameter for dcraw_emu sample * Parameter -s N (select shot number) added to unprocessed_raw sample. * Imported dcraw 8.90/1.414: + changes in QuickTake 100 metadata processing + changes in external jpeg processing code + Samsung S85 support * All client code should be recompiled * LibRaw 0.7.0-Alpha3 released 2009-01-10 Alex Tutubalin <lexa@lexa.ru> * Fixed bug in add_masked_borders: crash if output dimensions is already larger than raw dimensions * Fixed out of bounds in samples/unprocessed_raw.cpp for files with non-square pixels * LibRaw 0.7.0-Alpha2 released 2009-01-08 Alex Tutubalin <lexa@lexa.ru> * Fixed bug in 0.7.0-a0: black frame size has not reset, so in batch processing there is an error in black frame size for files without black frame. * Implemented reading of black/masked pixels data for near all cameras with masked pixels, exclding: + Canon sRAW, Leaf (MOS), Sinar 4-shot - more than one color component in black frame (redesign of black frame data structures required). + Fuji SuperCCD: need to design right methods of extraction (should we rotate and resize black pixels as active ones??) * Tested for most dSLR data formats with masked pixels: 7 of 9 untested formats are from old P&S cameras. * New call LibRaw::unpack_function_name() returns unpack function name (useful for testers only) * New identify sample parameters (useful for test-suite builders to check test coverage): -u - print unpack function name -f - print masked frame size These parameters works only for identify run without -v parameter * Imported dcraw 8.89/1.411 + changes in Panasonic FZ50 files parsing * LibRaw 0.7.0-Alpha1 released 2009-01-05 Alex Tutubalin <lexa@lexa.ru> * It is possible to turn off RAW data filtration (black level subtraction, zero pixels averaging): + supported on all cameras except Foveon and Phase One + filtraction controlled by new parameter "filtering_mode" + it is possible to expand API by filtering procedures built for specific camera model. * Black border (masked pixels) extraction: + API (data structures) for storing black mask. + Black mask extraction supported only for limited list of data formats: - Canon .CRW, .CR2 (with exception of sRAW),A600, A5 - Adobe DNG (both converted RAW and native DNG) - Nikon NEF (compressed only) this list to be expanded in future LibRaw versions * New call add_masked_borders_to_bitmap makes full bitmap 'masked border' + image * Usage sample for functionality listed above: samples/unprocessed_raw * Imported dcraw 8.89/1.410: + fixed bugs in Hasselblad .fff decoding + fixes in Imacon metadata decoding * Documentation changes * All client code should be recompiled * LibRaw 0.7.0-Alpha0 2009-01-01 Alex Tutubalin <lexa@lexa.ru> * Fixed a bug (filedescriptor and buffer memory leak) in thumbnail extraction when called before metadata analysis.
