Make icon edge transparent (from white background) in Paint.NET Discussion and Questions Posted May 1, 2015 See if this makes them look OK: Set Magic Wand tolerance to zero. Click on white > Delete. Apply AA's Assistant plugin effect at default settings. I'm new to Paint.NET, started off looking for the Magic Want in vanilla paint... So, having set Magic Wand Tolerance to zero, where do I find "white" and "Delete" ?
