Do we have any programming/graphic related people in the forums that understand Class "Y" (YCbCr, not RGB) Tiffs utilizing LZW and/or TifLib? I know it is a long shot but I thought I would take the chance and see.Markos, this IS CtP related, that is why it is here. Although I would have a better chance if it was in the Apolyton or OT forums.

The reason.....
to break the CtP(2) graphics files so I can create a pgm to add/change/modify them. This is THE biggest drawback to CtP2 and the 'New Terrain' thread brought this all back to light.From looking at the executable, I see where Activision licensed LZW (which is a class "Y" compression option), is using the YCbCr format (calls YCbCrToRGB) and is using a Tiff-Specific library. Initially, I thought Activision had their own proprietary library but I have changed my mind (at the moment). Another pgm I was checking into had a TifLib.Dll file which lead me to TifLib. The Tiff calls Activision makes and the TifLib calls are virtually identical. Also, TifLib supports 'Directories' which is how multiple images in 1 file are accessed. By putting all these pieces together, I *think* I am on the right track. If not, I am thinking I still might be able to use this Library to access the graphic files. And since I know squat about these graphics files, I was hoping somebody might have a little knowledge in this area. EDIT: http://www.libtiff.org

EDIT: Sorry, decided not to post my comments about the OT forum and the conversations about wiping their rears. Lets just say it is a strange place at times.
