TIFFWriteEncodedTile(3T)TIFFWriteEncodedTile(3T)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(3T) rou-
tine.
%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 TIFFSet-
Field(3T).
%s: Must set "ImageWidth" before writing data. The
image's width has not be set before the first write. See
TIFFSetField(3T) 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(3T) 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.
