Winforms semi-transparent PNG over semi-transparent PNG
I am about to make a project of the game Risk in school and my teacher said that's possible, but we are only to use Windows Form and not XNA or other tools.
In Risk, as you probably know if you know the game, the map is built up on many countries and every country should be it's own picture, since it has it's own effects, so to say.
So is it possible, with PictureBox, so change it to have a "transparental" effect and cover the picture only and not be like a box around the picture?
Sorry if this was a bad written description!
