glacialfury Posted September 12, 2007 Share Posted September 12, 2007 I'm trying to create a simple drawing program with layers. The default bottom layer is a grid that can be shown or not shown. The drawing must occur over the grid (it's used only for guidelines), so it needs to be on the bottom. The problem is, my current method of erasing is to use the background color and draw over it. This effectively draws a white line, which obscures bits of the grid. I've tried drawing with "Transparent" as the color, but then nothing shows up at all. How do you truly create an eraser effect, which will remove the previous drawing on a given layer without obscuring the layers below? Any tips or alternate methods are greatly appreciated.
