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) 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(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.
