TIFFWriteEncodedTile

compress and write a tile of data to an open TIFF file

#include <tiffio.h>



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() <#c.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 TIFFErrorExtR() <#c.TIFFErrorExtR> 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() <#c.TIFFSetField>.


%s: Must set "ImageWidth" before writing data:

The image's width has not been set before the first write. See TIFFSetField() <#c.TIFFSetField> 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() <#c.TIFFSetField> 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.
