Thanks,

Because the CCITTFactory can only process TIFF files whose content can 
be used 1:1 (minus the tiff header). The PDF CCITTFaxDecode filter does 
not support uncompressed data.

If you still want to use CCITT compression, please load and then save 
your stuff as a TIFF file (use the ImageIOUtils methods) and use these 
files.

If this is too difficult, then use the LosslessFactory methods.
