TIFFDefaultStripSize, TIFFStripSize, TIFFVStripSize, TIFFComputeStrip, TIFFNumberOfStrips − strip-related utility routines
#include
<tiffio.h>
uint32 TIFFDefaultStripSize(TIFF* tif, uint32 estimate)
tsize_t TIFFStripSize(TIFF* tif)
tsize_t TIFFVStripSize(TIFF* tif, uint32 nrows)
tstrip_t TIFFComputeStrip(TIFF* tif, uint32 row, tsample_t
sample)
tstrip_t TIFFNumberOfStrips(TIFF* tif)
TIFFDefaultStripSize returns the number of rows for a reasonable-sized strip according to the current settings of the ImageWidth, BitsPerSample, SamplesPerPixel, tags and any compression-specific requirements. If the estimate 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 RowsPerStrip tag. In lieu of any unusual requirements TIFFDefaultStripSize tries to create strips that have approximately 8 kilobytes of uncompressed data.
TIFFStripSize returns the equivalent size for a strip of data as it would be returned in a call to TIFFReadEncodedStrip or as it would be expected in a call to TIFFWriteEncodedStrip.
TIFFVStripSize returns the number of bytes in a strip with nrows rows of data.
TIFFComputeStrip 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 row parameter is always used in calculating a strip. The sample parameter is used only if data are organized in separate planes (PlanarConfiguration=2).
TIFFNumberOfStrips returns the number of strips in the image.
None.
