TIFFWritedEncodedTile - compress and write
a tile of data to an open TIFF
file
#include <tiffio.h>
tsize_t TIFFWriteEncodedTile(TIFF
*tif, ttile_t tile, tdata_t buf, tsize_t size)
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.
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.
-1 is returned if an error was encountered. Otherwise, the value of
size is returned.
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.
