There is some discussion of OJPEG implementation in various threads of this mailing list, one has the subject "Microsoft Imaging and Jpeg in TIFF".

Archives to view these discussions are on: http://www.remotesensing.org/lists/libtiff_archive/mail4.html

Some messages not in that archive are on http://voila.egroups.com/group/tiff/info.html.

What do people think about actually writing the code to read these proprietary TIFF-variants? That would mean using clumsy temp files to extract JFIF files and using then libjpeg to access a raster in memory, or perhaps some other method would work.

Here are some makers of "OJPEG" files: PixTran, Wang, HP; what are others? They can perhaps be differentiated by their TIFFTAG_SOFTWARE, where otherwise each claims to be OJPEG.
