Hi, I got a problem in metapost. If I want to draw a ring, and use the code: fill fullcircle scaled 2cm ; unfill fullcircle scaled 1cm ; The inner part is not transparent, it has the color of "background" variable which is "white" by default.
This case is a minimal example, I actually wanna draw something more complex, like the glyph "Q" and I know the inner path and outer path. How can I fill the ring without jeopardizing the area inside the inner path?
fill fullcircle scaled 2cm -- reverse -- fullcircle scaled 1cm -- cycle ; Wolfgang
