CM0 Posted August 7, 2023 Share Posted August 7, 2023 When you export an art board, groups will be rendered in 'normal' vs 'passthrough'. At least that is what appears to happen. This is a sample before export. This is what it looks like exported. This bug probably went unnoticed because the difference is subtle in some cases. Blend ranges is applied to easily see how they are different. Sample that reproduces problem attached. Note, same thing happens if you do 'rasterize' layer. Also, if you change the blend mode from 'passthrough' to 'normal' it will look the way it is exported. -------------------- Windows 10. Affinity 2.1.1.

You can see the preview in export is already incorrect. Also, rasterizing the layer will result in incorrect pixel layer as well. Nonetheless, was using PNG with defaults. walt.farrell 1 Quote Link to comment Share on other sites More sharing options...
Dan C Posted August 8, 2023 Share Posted August 8, 2023 Hi @CM0, Thanks for your report! Interestingly with this file, I've found the following behaviour: When opened within Affinity Publisher (or the Designer /Photo Personas of Affinity Publisher) the file renders differently on canvas compared to the export when using an Artboard. When using a regular canvas with a rectangle as the background colour, the file exports the same as is shown in the app. When opened within Affinity Designer, the Artboard document renders the same as the exported image. When using a regular canvas the file renders the same as it's exported counterpart, though differently compared to the export of the Artboard document. When opened within Affinity Photo, both the Artboard and canvas document render the same as the exported image. I can't entirely explain this behaviour currently and I suspect the version that matches the exported file is correct and should be seen in all instances of app/artboard/canvas combinations - therefore I'll be logging this with our development team now for further investigation. I hope this helps CM0 1 Quote Link to comment Share on other sites More sharing options...
CM0 Posted August 8, 2023 Author Share Posted August 8, 2023 Important note. I tried what you did above. Looks like you discovered an additional problem. The rendering in Photo is broken. It completely ignores the blend ranges set on the group. The correct rendering and export should be. Dan C 1 Quote Link to comment Share on other sites More sharing options...

CM0 Posted August 8, 2023 Author Share Posted August 8, 2023 But that still doesn't work. You added a square within the same group to get the same effect. The 'passthrough' mode seems to be ignored. The square should not be needed. Quote Link to comment Share on other sites More sharing options...

CM0 Posted August 8, 2023 Author Share Posted August 8, 2023 I'm not sure what you are proposing. You posted a file with no context or explanation. If you are proposing a work around, I understand the suggestion. However, I just want to make sure it is understood this a problem and not behaving as intended. Not just the export, but the render itself in photo. I created this trivial example as a way to understand the problem. The work around works for this example. However, it is not a work around for a complex composition. Quote Link to comment Share on other sites More sharing options...
Old Bruce Posted August 8, 2023 Share Posted August 8, 2023 I am a bit confused. Here on my Mac i get an A with a gradient/transparency yet there is no gradient/transparency applied. I cannot get the A to be a solid colour. Yes I am removing the blend I wonder how the A was created. If I type an A it is solid white from top to bottom not fading from Clear to White top to bottom.

I have never mastered color management, period, so I cannot help with that. Link to comment Share on other sites More sharing options...
Return Posted August 8, 2023 Share Posted August 8, 2023 BTW why do you have a linear transparency from black to white and a blendrange? I'm trying to understand what the end result should look like with your example file. Quote Link to comment Share on other sites More sharing options...
Return Posted August 8, 2023 Share Posted August 8, 2023 You mask the A with a rectangle with black/100% to black/0% fill color and get the same result without blend ranges. Why is that blend range even there? It doesn't do anything special here. Quote Link to comment Share on other sites More sharing options...

CM0 Posted August 8, 2023 Author Share Posted August 8, 2023 Ok, here is something I did quickly just as a demonstration that there are unique effects you can create not possible without the combination and in the right order. The Art Board at the bottom right "Transparency + Blend Ranges" is the desired effect. We are capturing the highlights of the sand and want a natural organic falloff into darkness as it approaches the top of the image. We can not do that with transparency alone, we can not do this with blend ranges alone, and we can't do it in the wrong order with blend ranges first and then transparency. Note, in a real composition I might use something other than a transparency gradient. Could be a curves adjustment in combination with transparency gradient etc. As what we are doing is changing what parts of the image will cross the blend ranges threshold so that we have more fine control of how the effect is applied across different parts of the image.

Not really needing any specific help at this point other than just getting the problem recognized and bug fixed. I wanted to make sure the problem is understood so the right "fix" is applied. Which is why I wanted to make sure that it is understood Photo's default rendering is incorrect. I'm just hoping a mod could confirm. Thanks.

I can confirm that I've updated the development log to include this information and your file above - such that this can be correctly understood and resolved in a future update.
