How about using PostScript commands for creating the zigzag pattern? I'm thinking in terms of repeating the following PostScript commands as a "stencil": x y 2 / rlineto x -y rlineto x y 2 / rlineto In this code, x is the x step increment of the zigzag, and y the y step increment, in case you want to tweak the zigzag appearance. I only do not know yet how to add the PostScript in a stencil. Best regards, Olivier
