It's pretty straight forward. It renders each layer into a separate pbm, then composites them into a single ppm. The compositing loop is around line 688 in hid/png/png.c. There's a little extra code for figuring top/bottom shadows, computed by ts_bs() and ts_bs_sm(), and for texturing the copper (the call to random()). _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
