26 .TH TIFFReadRawTile 3T "October 15, 1995"
28 TIFFReadRawTile \- return an undecoded tile of data from an open
32 .B "#include <tiffio.h>"
34 .B "tsize_t TIFFReadRawTile(TIFF* tif, ttile_t tile, tdata_t buf, tsize_t size)"
36 Read the contents of the specified tile into the
37 (user supplied) data buffer.
38 Note that the value of
40 is a ``raw tile number.''
41 That is, the caller must take into account whether or not the
42 data is organized in separate planes (\c
43 .IR PlanarConfiguration =2).
45 automatically does this when converting an (x,y,z,sample)
46 coordinate quadruple to a tile number.
47 To read a full tile of data the data buffer should typically be
48 at least as large as the value returned by
51 The actual number of bytes of data that were placed in
54 .IR TIFFReadEncodedTile
55 returns \-1 if an error was encountered.
57 All error messages are directed to the
63 .IR TIFFReadEncodedTile (3T),
