Is there anyway to set a "transparent" stroke color or is there any other way to clear the content of the layer on the Canvas above the background image called CGContextRef under the user's finger, when he moves it, like drawing Canvas1.dragged with Canvas1.paintColor.None?
I tried to create undo and rubber with the transparent color In the block above, that works perfectly with Canvas in Android, but in the ios canvas doesn’t work.
I tried write in hex instead of decimal #00FFFFFFF or #00000000 and make color black/white
with density 0%
Is there any way to do it in ios?
Thanks
