--- Comment #4 from Tymond <[email protected]> --- Created attachment 121532 --> https://bugs.kde.org/attachment.cgi?id=121532&action=edit Screenshot of the workaround + new mode This is the result of my work for now. On the left, you can see the workaround with a group that has a black layer on Normal mode (let's call it "workaround middle layer"), then a layer with the new color in Normal mode (let's call it "workaround top layer"), and then the whole group is in Addition mode (let's call it "workaround group"). Right side is my new blending mode. Color values are just the same, I checked it. I have a question how this blending mode should behave while being on a layer that has a lower opacity than 50%. On the right side of the screenshot you can see two rows of smaller yellowish-whitish circles. The first row is compiled out of 9 circles painted with 20, 50, 40 etc. to 100% of opacity. The second one is the same layer, but the opacity of the layer is 50%. As you can see, the brightest circle on the layer is yellow and looks the same as 50% opacity circle in the top row. On the left side there are two rows under the first "reference" one - first one is when you lower the opacity of the "workaround top layer" to 50%. The second one is when you lower the opacity of the "workaround group" to 50%. The first row has values identical to what you can get in the new blending mode. The second one is an example of how I can make it behave. The question is, whether you think it should behave (after lowering opacity of the layer) like the second small circle row or like the third one? What about making a transparency mask? (If I leave it as it is, it will be always consistent; I'm just not sure if it's what is expected. This is the first blending mode that uses alpha for something else than just blending two output colors together, here we calculate the result color using the alpha value). If you don't have a preference, please tell me so, too. Another question: do you have an access to SAI or Photoshop? I need to know what the value of the color is if you put a layer of color (10, 100, 200) in 30% and on top of that color (250, 200, 150) in 50% in the Luminosity (SAI) blending mode. Workaround don't work at all on that example and I think my blending mode can have "incorrect" colors there. -- You are receiving this mail because: You are watching all bug changes.
