NAME
TIFFWritedEncodedTile - 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 places (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
TIFFError(3TIFF)
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(3TIFF).
%s: Must set "ImageWidth" before writing data. The image's width has not
be set before the first write. See
TIFFSetField(3TIFF)
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(3TIFF)
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.
