Michael Allman Posted May 25, 2023 Share Posted May 25, 2023 When I load the attached TIFF file into AP 2.1.0, I only see black. However, this file has an alpha channel, and it should appear like a fuzzy black blob on a transparent background. I would expect that transparency to look like a checkerboard, like I see when loading the file in Photoshop.MetalPaint.tiff Please refer to the discussion here: Quote Link to comment Share on other sites More sharing options...

Staff Dan C Posted May 26, 2023 Staff Share Posted May 26, 2023 Hi @Michael Allman, Thanks for your report! As mentioned in your linked thread, I believe this is the consequences of changes to how Affinity Photo V2 handles Alpha layers in TIFF files - however I'm not 100% certain of the intentions here, as I can see V1 visually opens the file as you'd expect, but does not include this unassociated alpha layer. Therefore I'm logging this with our development team now for further clarification, and I will be sure to update you here with any information I am provided Quote Please note - I am currently out of the office for a short while whilst recovering from surgery (nothing serious!), therefore will not be available on the Forums during this time. Should you require a response from the team in a thread I have previously replied in - please Create a New Thread and our team will be sure to reply as soon as possible. Many thanks!

Unassociated Alpha.mp4 1.18 MB · 0 downloads Hi @Hangman. Thank you for posting this workflow, however my bug report is that AP does not show transparency when loading the attached TIFF file. We've seen at least two workflows (including yours) to get it to do so _after_ the file has been loaded, but that's not really what my bug report is about. Cheers.

Hangman Posted May 26, 2023 Share Posted May 26, 2023 Hi @Michael Allman, Completely understand, that was more of a workaround incase you were 'stranded' so to speak. As @Dan C mentions above he's logged the issue with the Serif development team for further clarification as to how this should work in practice in v2...

Old Bruce Posted May 26, 2023 Share Posted May 26, 2023 @Michael Allman, Myself, I am curious as the origin of the TIFF. Is it perhaps it is a TIFF with layers from Photoshop or another third party application which can save TIFFs with layers? Quote Mac Pro (Late 2013) Mac OS 12.7.4 Affinity Designer 2.4.1 | Affinity Photo 2.4.1 | Affinity Publisher 2.4.1 | Beta versions as they appear. I have never mastered color management, period, so I cannot help with that. Link to comment Share on other sites More sharing options...

The image was generated by a toy Mac app I wrote for simple interactive brush-based "painting". The image itself is just a "blob" or "stamp" of a brush. In fact, if you use the AP Paint Brush Tool to paint a single blob of a brush with width 1000 px, opacity 100% and hardness 0%, you will see something very similar.
