CPI to RAD Conversion: FAQ

What are CPI files?

Calamus was designed for the Atari ST, which was an innovative brand of home computers at the time, and was one of the first vector handling programs to include its own proprietary vector formats, as well as support virtual objects and frames. Since its release, Calamus had several subsequent upgrades and its latest version is Calamus SL2006.
