Hmm, I'm, using solid pink (0xFF00FF) as my masking colour, so if a wall texture's pixels are 0xFF00FF, they won't be drawn and you can see behind them. But when I save the pictures, they lose the exact colour 0xFF00FF, even when on high quality. The transparency works when the masking colour is set to black, because that colour is not lost. Is there a way to 100% keep colour when saving the image? Better yet is there a way of seeing is a colour is approximately 0xFF00FF, with a small margin?
