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.
