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
