Jimo Posted November 17, 2021 Posted November 17, 2021 (edited) Hi. I'm trying to figure out why I'm getting an undesirable border of lighter pixels around the edges of text in Affinity Photo. I've attached an image of example text to show what I mean. It is NOT a text decoration or effects border - neither of those are active - and the 'border' of pixels remains when rasterised and/or exported. I've recreated exactly the same test text in Affinity Designer and there is no border on the text. I have ALSO literally copied and pasted the text frame from Photo to Designer and the border of pixels have gone. However, if I open the actual original AfPhoto document in Designer, then the light pixelated border remains. Is there something at the document level I'm not aware of that I need to set, or if not, what is the solution? Or is this a bug? Help and insight would be appreciated. Thank you.

NotMyFault Posted November 17, 2021 Posted November 17, 2021 That’s anti-aliasing, a method to smooth edges, and applied by default. You can turn it off in the text layer blend range settings. https://affinity.help/photo/English.lproj/pages/Layers/layerBlendRanges.html Quote Mac mini M1 A2348 | MBP M3 Windows 11 - AMD Ryzen 9 5900x - 32 GB RAM - Nvidia GTX 1080 LG34WK950U-W, calibrated to DCI-P3 with LG Calibration Studio / Spider 5 | Dell 27“ 4K iPad Air Gen 5 (2022) A2589 Special interest into procedural texture filter, edit alpha channel, RGB/16 and RGB/32 color formats, stacking, finding root causes for misbehaving files, finding creative solutions for unsolvable tasks, finding bugs in Apps.

Jimo Posted November 17, 2021 Author Posted November 17, 2021 (edited) Well it's NOT anti-aliasing - switching that off just leaves me with pixelated text. But after performing a few more experiments I think I might have party figured something out. Firstly, I've updated to the latest version of Photo (I was only on version 1.9.2 I think), although the border on the text remains after updating. However, it seemed to have something to do with the background colour. The hex value is 1A171B. I was using CMYK sliders to select the colour in the first place I think. If I switch to HSL and use exactly the same hex value, the border disappears when I add the new background - although of course there is also a slight tonal change in the background colour. If I then switch BACK to using the CMYK sliders and put in the same hex value again, it remains fine (the border on the text doesn't return - although the same background tone doesn't return either). Maybe updating fixed it? I can't be sure (I'm tempted to reinstall the slightly older version to put it to the test!). Perhaps I had some colour format conflict, but I can't recreate it from scratch now. Only by literally copying my original background brings the unwanted border back. Using Designer, changing the colour format in Document Setup also fixed the problem, but I can't find anywhere in Photo to do the same. I'm still puzzled as to why it happened in the first place though. Edited November 17, 2021 by Jimo Quote

If you mean the stair step edges, that is an unavoidable consequence of forcing off antialiasing.

Dan C Posted November 18, 2021 Posted November 18, 2021 Hi @Jimo, Thanks for the file provided! I can confirm this appears to be Colour Profile related, as it only happens with the Coated FOGRA27 profile applied to the .afphoto file. I suspect when creating new documents in Designer, these were created using a different colour space/profile where the issue does not show, as I'm able to replicate this behaviour here. 14 hours ago, Jimo said: Using Designer, changing the colour format in Document Setup also fixed the problem, but I can't find anywhere in Photo to do the same. Within Affinity Photo, you can do this by selecting Document > Convert Format / ICC Profile... 14 hours ago, Jimo said: I'm still puzzled as to why it happened in the first place though. I believe this to be an issue with Affinitys 'document to screen' colour conversion, with this CMYK profile and the specific colours used in your document - although I myself am not 100% certain of this, so I'll be logging the file with our developers now for further investigation. I hope this helps! walt.farrell and Jimo 2 Quote
