I seem to recall that some time back Tom Lane sent out a note of alarm about the bogus JPEG implementation in the Wang package; most of the code is very old and so it could very well be that it mangles the G4 compressed stream as well.

Someone might be interested in this. I am using Imaging for Windows as a viewer for G4 TIFF files created with libtiff. It works well except that the files are MINISBLACK, and Imaging display them in negative. It looks like Imaging does not read the PhotometricInterpretation tag, and wrongly assumes it is MINISWHITE.
