IOS : cannot clear transparent background drawing

[jscti]

Seems like clearing a drawing on IOS works only when dealing with opaque colors.

I need to draw on an image , And I need to clear the drawing if needed.

Tried both clear() and clearWithColor() but :

• clear() or clearWithColor with an opque color = fill all with a color (= no transparency of course)
• clearWithColor with a transparent color = wont erase the content before applying (adding) a transparent color = fail

How can I erase the drawing and having it back to transparent ?
Thanks

Not sure at the moment, have you looked at the source to see how the clear drawing works? Might be something trivial to fix but I've not had time to look at this myself. If you find anything useful and want to contribute a PR it will be accepted 💯
