GAMGI uses the file extension to automatically determine the file format. To export a standard .jpeg file of the whole graphic area of a GAMGI window, just give the filename the extension .jpeg or .jpg.

The command line application pnmtojpeg, widely available and usually installed by default in most Linux distributions, must be installed, otherwise GAMGI will be unable to export a jpeg file.

This a loss infomation format, not particularly recommended, particularly when rendering wired objects such as cells and text. Currently the quality parameter is set to 75% (the pnmtojpeg default).
