NAME
TIFFDefaultStripSize, TIFFStripSize, TIFFVStripSize, TIFFRawStripSize, TIFFComputeStrip, TIFFNumberOfStrips - strip-related utility routines
SYNOPSIS
#include <tiffio.h>
uint32_t TIFFDefaultStripSize(TIFF **/tif/, uint32_t estimate)*
tmsize_t TIFFStripSize(TIFF **/tif/)*
tmsize_t TIFFVStripSize(TIFF **/tif/, uint32_t nrows)*
tmsize_t TIFFRawStripSize(TIFF **/tif/, uint32_t strip)*
tstrip_t TIFFComputeStrip(TIFF **/tif/, uint32_t row, tsample_t
sample)*
tstrip_t TIFFNumberOfStrips(TIFF **/tif/)*
DESCRIPTION
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.
TIFFRawStripSize returns the number of bytes in a raw strip (i.e. not decoded).
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.
DIAGNOSTICS
None.
