Michael Lowden Posted March 31, 2017 Share Posted March 31, 2017 I have an issue when merging from a partially transparent (~30%) layer down to a 100% layer. The transparency gets dropped and seems to inherent the 100% of the lower layer. Am I using it wrong? Quote --forget PhotoShop or PaintShopPro .. THIS is the only tool the most of us need.

IRON67 Posted March 31, 2017 Share Posted March 31, 2017 If the layer is 100% transparent, then there is in fact nothing to see and instead merging down the layer above you could simply delete the lower layer. If I've understand you in a wrong way, please describe it more precise and maybe with an screenshot for illustration. Quote Link to comment Share on other sites More sharing options...

If you have a partially transparent layer on top of an opaque layer, then before merging the combination will be opaque: none of the lower layers will show through. So the merged layer is also opaque. The alpha-blending equation is the sum of the alphas (considered as values between 0 and 1) minus their product. If either layer is opaque, the merged layer will be opaque (1 + a - 1 * a = 1). EDIT: Modified because I wasn't certain what some of what I'd said was precisely true.
