CRG to ICO Conversion: FAQ

What are CRG files?

The CRG format is associated with Calamus SL, an incipient desktop publishing software program released in the 1980s for the Atari ST, a then popular brand of home computers. Compared to previous programs with similar functions, the Calamus SL included innovative features for handling vector files, such as virtual objects, non-destructive vector masks and PDF import. Calamus was also the first DTP program to feature proprietary image formats, such as CPI and CRG. The program continues to be supported by the current owner, the German developer Invers Software.
