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.
