Are you trying to create an eraser? If so you may have to write your
own custom CIKernel which modifies the alpha of the image. If you'd
like post a simple example which illustrates the flickering. It
sounds like you are on to something, but this may not be achievable
with the CIAccumulator.

Hi all,
I'm sure it's just my newness to image processing and QC, so I
apologise if there's an obvious solution to this.
I'm trying to modify the Image Accumulator example so that the
mouse 'paints' transparency, allowing one to see through to what's
beneath. I've messed around with alpha and blend settings, and
tried Source Out instead of Source Over (sort of works, but the
'background' flickers between transparent and black when I paint')
but I can't seem to get the right combination of settings.
Can someone point me in the right direction?
Thanks,
Scott Wilson
