The issue is that we want to end up with some sections filled in, and some not. The user needs be able to select and deselect sections as needed, there needs to be some transparency to be able to see the underlying image. If the idea was just to draw circles or filled circles, this application would be simple. I am going to show you where I am with this. I think by you seeing the way it works, you can see what the goals are. Since my last post, I was able to:
1) simulate transparency and increase speed by drawing fewer circles and using dashed line draws (and decimating image).
2) complete the deselection portion of the code
3) add an option for drawing either circles or squares
It works better and faster now - but I still look for creative ways for instantaneous draws of transparent sections.
