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.
Diagnostics
All error messages are directed to the TIFFErrorExtR() routine.
%s:Filenotopenforwriting:
The file was opened for reading, not writing.
Cannotwritetilestoastrippedimage:
The image is assumed to be organized in strips because neither of the TileWidth or TileLength tags
have been set with TIFFSetField().
%s:Mustset"ImageWidth"beforewritingdata:
The image's width has not been set before the first write. See TIFFSetField() for information on how
to do this.
%s:Mustset"PlanarConfiguration"beforewritingdata:
The organization of data has not be defined before the first write. See TIFFSetField() for
information on how to do this.
%s:Nospacefortilearrays":
There was not enough space for the arrays that hold tile offsets and byte counts.
Name
TIFFWriteEncodedTile - compress and write a tile of data to an open TIFF file
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.
