NAME
TIFFsize - return the size of various items associated with an open
TIFF file
SYNOPSIS
#include <tiffio.h>
tsize_t TIFFRasterScanlineSize(TIFF *tif)
uint64_t TIFFRasterScanlineSize64(TIFF *tif)
tsize_t TIFFScanlineSize(TIFF *tif)
uint64_t TIFFScanlineSize64(TIFF *tif)
DESCRIPTION
TIFFScanlineSize() returns the size in bytes of a row of data as it
would be returned in a call to TIFFReadScanline(), or as it would be
expected in a call to TIFFWriteScanline(). Note that this number may
be 1/samples-per-pixel if data is stored as separate planes. The
ScanlineSize in case of YCbCrSubsampling is defined as the strip size
divided by the strip height, i.e. the size of a pack of vertical
subsampling lines divided by vertical subsampling. It should thus make
sense when multiplied by a multiple of vertical subsampling.
TIFFScanlineSize64() returns the size as uint64_t.
TIFFRasterScanlineSize() returns the size in bytes of a complete
decoded and packed raster scanline. Note that this value may be
different from the value returned by TIFFScanlineSize() if data is
stored as separate planes. TIFFRasterScanlineSize64() returns the size
as uint64_t.
DIAGNOSTICS
None.
