NAME
TIFFWriteEncodedTile - compress and write a tile of data to an open
TIFF file
SYNOPSIS
#include <tiffio.h>
tsize_t TIFFWriteEncodedTile(TIFF *tif, ttile_t tile, tdata_t buf,
tsize_t size)
DESCRIPTION
Compress size bytes of raw data from buf and append the result to the
end of the specified tile. Note that the value of tile is a "raw tile
number". That is, the caller must take into account whether or not the
data are organized in separate planes (PlanarConfiguration = 2).
TIFFComputeTile() automatically does this when converting an
(x,y,z,sample) coordinate quadruple to a tile number.
NOTES
The library writes encoded data using the native machine byte order.
Correctly implemented TIFF readers are expected to do any necessary
byte-swapping to correctly process image data with BitsPerSample
greater than 8.
RETURN VALUES
-1 is returned if an error was encountered. Otherwise, the value of
size is returned.
DIAGNOSTICS
All error messages are directed to the TIFFErrorExtR() routine.
%s: File not open for writing:
The file was opened for reading, not writing.
Can not write tiles to a stripped image:
The image is assumed to be organized in strips because neither of
the TileWidth or TileLength tags have been set with TIFFSetField().
%s: Must set "ImageWidth" before writing data:
The image's width has not been set before the first write. See
TIFFSetField() for information on how to do this.
%s: Must set "PlanarConfiguration" before writing data:
The organization of data has not be defined before the first write.
See TIFFSetField() for information on how to do this.
%s: No space for tile arrays":
There was not enough space for the arrays that hold tile offsets and
byte counts.
