Jerome O'Flaherty commented on FOP-2435:
----------------------------------------
Guys,
Sorry for dragging up this old ticket but I am interested in understanding
TIFF LZW in IOCA, I cannot find information about the way the TIFF in actually
encoded within IOCA. I can decode the ImageBandData and the Tiles but the raw
Bytes do not seem to match the actually TIFF LZW decoder format? Can anyone
point me in the direction of a format specification and/or some sample code to
decoder/encoder for IOCA Images with TIFF LZW compression?
Thanks
Jerome
