On the other hand, the Ceder Chest Definitions on the web located at http://www.ceder.net/def.php are made with color GIFs. These diagrams were generated via our CSDS program (which produces bitmap files) and a graphics program such as MS Paint (to convert the bitmap files into GIF format). CSDS can also generate bitmap diagrams in black & white, with or without couple numbers. To use the CSDS program to create diagrams, you must first purchase the program (the demo version is $25, the full version is $200). The demo version has no restrictions on creating graphics. To generate diagrams, first create a sequence starting from a squared set, entering calls to get to the desired position, then select a menu option to create a bitmap file. It's easy (so far I've done almost 3000 diagrams for our web definitions).
