AlanH Posted March 16, 2017 Share Posted March 16, 2017 Transparent PNG export used to be trivial with Paintshop Pro 9 - PNG export asked what colour I wanted to be transparent, and that was sorted. But I'm struggling with Affinity Photo (and Designer - I have and use both). Example: I have a JPG snippet of music score - black notes on white background. I simply want to invert to white notes, and export a PNG where the resultant (black) background is clear, for use as an overlay image in a video project. I start with document option for transparent background checked. I can apply an Invert adjustment to get white notes on black background, but where do I go from there? I cannot find any blend options that turn the black clear, and there is no 'this colour will be transparent' option in any PNG export dialogue, as far as I can see. This is such a fundamental procedure that I'm sure it must be explained somewhere but, for the life of me, I can't find it. Any ideas? Thanks!

Staff MEB Posted March 16, 2017 Staff Share Posted March 16, 2017 Hi Alan, Starting with the original image - black notes on white background - go to menu Filters ▸ Colours ▸ Erase White Paper to remove the background then invert the colours (menu Layer ▸ Invert) and export as PNG.

AlanH Posted March 16, 2017 Author Share Posted March 16, 2017 Aha! I knew it must be simple. Had not looked at those filters - still getting used to the workflow - all a bit of a culture shock after nearly 20 years with JASC! Thanks for the quick reply!
