If the <i>estimate</i> parameter, if non-zero, then it is taken as an estimate of the desired strip size and adjusted according to any compression-specific requirements. The value returned by this function is typically used to define the <i>RowsPerStrip</i> tag. In lieu of any unusual requirements <i>TIFFDefaultStripSize</i> tries to create strips that have approximately 8 kilobytes of uncompressed data.</p> <p style="margin-left:11%; margin-top: 1em"><i>TIFFStripSize</i> returns the equivalent size for a strip of data as it would be returned in a call to <i>TIFFReadEncodedStrip</i> or as it would be expected in a call to <i>TIFFWriteEncodedStrip</i>.</p> <p style="margin-left:11%; margin-top: 1em"><i>TIFFVStripSize</i> returns the number of bytes in a strip with <i>nrows</i> rows of data.</p> <p style="margin-left:11%; margin-top: 1em"><i>TIFFRawStripSize</i> returns the number of bytes in a raw strip (i.e. not decoded).</p> <p style="margin-left:11%; margin-top: 1em"><i>TIFFComputeStrip</i> returns the strip that contains the specified coordinates. A valid strip is always returned; out-of-range coordinate values are clamped to the bounds of the image. The <i>row</i> parameter is always used in calculating a strip. The <i>sample</i> parameter is used only if data are organized in separate planes (<i>PlanarConfiguration</i>=2).</p> <p style="margin-left:11%; margin-top: 1em"><i>TIFFNumberOfStrips</i> returns the number of strips in the image.</p> <h2>DIAGNOSTICS <a name="DIAGNOSTICS"></a> </h2> <p style="margin-left:11%; margin-top: 1em">None.</p> <h2>SEE ALSO <a name="SEE ALSO"></a> </h2> <p style="margin-left:11%; margin-top: 1em"><b>TIFFReadEncodedStrip</b>(3TIFF), <b>TIFFReadRawStrip</b>(3TIFF), <b>TIFFWriteEncodedStrip</b>(3TIFF), <b>TIFFWriteRawStrip</b>(3TIFF), <b>libtiff</b>(3TIFF),</p> <p style="margin-left:11%; margin-top: 1em">Libtiff library home page: <b>http://www.simplesystems.org/libtiff/</b></p> <hr> </body> </html>
