NAME

6       TIFFReadRawTile  -  return  an undecoded tile of data from an open TIFF
7       file
8

SYNOPSIS

10       #include <tiffio.h>
11
12       tsize_t TIFFReadRawTile(TIFF *tif, ttile_t tile, tdata_t  buf,  tsize_t
13       size)
14

DESCRIPTION

16       Read  the  contents of the specified tile into the (user supplied) data
17       buffer.  Note that the value of tile is a ``raw tile number.'' That is,
18       the  caller must take into account whether or not the data is organized
19       in separate planes (PlanarConfiguration=2).  TIFFComputeTile  automati‐
20       cally  does this when converting an (x,y,z,sample) coordinate quadruple
21       to a tile number. To read a full tile of data the  data  buffer  should
22       typically be at least as large as the value returned by TIFFTileSize.
23

RETURN VALUES

25       The actual number of bytes of data that were placed in buf is returned;
26       TIFFReadEncodedTile returns -1 if an error was encountered.
27

DIAGNOSTICS

29       All error messages are directed to the TIFFError(3TIFF) routine.
