patches and overlapping alpha values
11 ビュー (過去 30 日間)
I wrote code that creates two patch objects which overlap each other. Basically, two circles, one (circle A) at the center of the other (circle B). Both have a face value of .35. Circle A is red and circle B is blue. However, when I set’ facealpha’ property while using the patch command, the colors add up, meaning that circle B is the alpha blue that I want, but circle A is an alpha purple (the alpha red and alpha blue added together). Is there a way to get circle A looking red again? My original plan is to "cut out" circle A then patch circle B, followed by patching circle A.
