tiffstrip(3)
NAME
TIFFDefaultStripSize, TIFFStripSize, TIFFVStripSize, TIFF
ComputeStrip, TIFFNumberOfStrips - strip-related utility
routines
SYNOPSIS
#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)
DESCRIPTION
TIFFDefaultStripSize returns the number of rows for a rea
sonable-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 com
pression-specific requirements. The value returned by
this function is typically used to define the RowsPerStrip
tag. In lieu of any unusual requirements TIFFDefault_
StripSize 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 TIFFReadEncoded_
Strip or as it would be expected in a call to TIFFWriteEn_
codedStrip.
TIFFVStripSize returns the number of bytes in a strip with
nrows rows of data.
TIFFComputeStrip returns the strip that contains the spec
ified coordinates. A valid strip is always returned; outof-range coordinate values are clamped to the bounds of
the image. The row parameter is always used in calculat
ing 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.
