There are lots of older graphics books that show how to do concave polygon
fills by counting the edges.. i.e. go raster by raster and determine whether
you are inside or outside of the polygon by counting how many lines you cross
from left to right.. or something like that.
yes but for this you need to be able to look at the display and see if a
pixel is on or not, right? I dont think there is any function in the Palm
OS to see if a pixel is on. That's the problem.
