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.
