Re: [Oiio-dev] How to properly composite two images?
Hi again! Got it working. Must have messed up something in my earlier attempts. Had to paste logo in the correct position in an empty buffer the size of my background first and then over that buffer over the background. Have a nice weekend!

[Oiio-dev] How to properly composite two images?
Hi! I'm attempting to composite two images, but having a hard time getting the result I'm after. It's a simple logo with alpha over a background situation. I've tried both ImageBufAlgo.paste() and ImageBufAlgo.over() with varying results. None of them yields the result I expected. The logo either gets a black background around it with ImageBufAlgo.paste() or applies transparency all the way through the background with ImageBufAlgo.over() I've also played around with ROI and channel range with no luck. Does anyone have any experience with this or have any pointers in any direction I can check out?
