iOSBitmap.Graphics.Mask?

Hello,
I think I know the answer already (‘not possible’) - is there a way of accessing an iOSBitmap’s mask? I want to draw a randomly stripy oval. My method on Desktop would be to draw a randomly stripy rectangle then mask it; I don’t think I can do that on iOS.
Any ideas?

You could use an iOSPath to mask the drawing, then draw the rectangle
