- .SH NAME
- TIFFReadRawTile \- return an undecoded tile of data from an open
- .SM TIFF
- file
- .SH SYNOPSIS
- .B "#include <tiffio.h>"
- .sp
- .BI "tsize_t TIFFReadRawTile(TIFF *" tif ", ttile_t " tile ", tdata_t " buf ", tsize_t " size ")"
- .SH DESCRIPTION
- Read the contents of the specified tile into the (user supplied) data buffer.
- Note that the value of
- .I tile
- is a ``raw tile number.'' That is, the caller must take into account whether
- or not the data is organized in separate planes (\c
- .IR PlanarConfiguration =2).
- .I TIFFComputeTile
- automatically does this when converting an (x,y,z,sample) coordinate quadruple
- to a tile number. To read a full tile of data the data buffer should typically
- be at least as large as the value returned by
- .IR TIFFTileSize .
- .SH "RETURN VALUES"
- The actual number of bytes of data that were placed in
- .I buf
- is returned;
- .IR TIFFReadEncodedTile
- returns \-1 if an error was encountered.
- .SH DIAGNOSTICS
- All error messages are directed to the
- .BR TIFFError (3TIFF)
- routine.
