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.
