However it only displays the red arc, it would appear that the polygon that is drawn in the alpha channel to mask off the non-drawn portion of the arc is masking off the next arc to be drawn. I would have thought with saving and restoring the context, this wouldn't be an issue. EDIT: It would appear the poly is just drawing itself in black, and not removing from the alpha channel?
Any help would be appreciated, cheers.
