NAME

TIFFsize - return the size of various items associated with an open
TIFF file

SYNOPSIS

#include <tiffio.h>

tmsize_t TIFFRasterScanlineSize(TIFF *tif)

uint64_t TIFFRasterScanlineSize64(TIFF *tif)

tmsize_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.
