File:Eps32x22ringRoster.jpg

Example of the roster graphics in EPS.

The black-gray-white rectangles are plotted with the EPS command image.

The red cross is drawn with the EPS commands moveto, lineto, stroke (simplified to M, L, S in the definitions in the beginning of the file).

The image is generated from with simple C++ program and converted to jpg format by the system command convert with the default options.
