Jonny.m5 Posted May 20, 2022 Share Posted May 20, 2022 Hey guys, I found this weird problem, while importing 32bit .tif files. Photoshop and Windows can preview them normally, but Affinity is adding white boarders around the white areas. Hope to get help here... Any idea what I am doing wrong? Thank you Jonny Quote Link to comment Share on other sites More sharing options...

NotMyFault Posted May 20, 2022 Share Posted May 20, 2022 it looks like a 32 bit greyscale image. Affinity seems to import this incorrectly (displayed as GREY/16, as Affinity does not support GREY/32). Assume this is a bug (if it's rated as missing feature, Affinity should provide an error message instead of silently importing it wrong). If possibly, try tiff/16, or EXR, HDR if you need to use 32 bit colour channels. I edited the file with Mac Preview and exported as TIFF GREY/16. that file imports correctly in Photo. https://affinity.help/photo/en-US.lproj/index.html?page=pages/Appendix/fileformat.html?title=Supported file formats Quote Mac mini M1 A2348 | Windows 10 - AMD Ryzen 9 5900x - 32 GB RAM - Nvidia GTX 1080 LG34WK950U-W, calibrated to DCI-P3 with LG Calibration Studio / Spider 5 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.

Jonny.m5 Posted May 20, 2022 Author Share Posted May 20, 2022 @NotMyFaultThank you very much! Is there a workaround? Can I import it with another Colorspace or anything? Or do you have a tool, where I could convert the image to hdr or exr 32 bit? Quote Link to comment Share on other sites More sharing options...
NotMyFault Posted May 20, 2022 Share Posted May 20, 2022 Windows has some Apps to edit images, try them out. On Mac, the Preview Apps does the job. Last resort option: try snipping tool, but this will probably reduce to 8 bit color depth.

Jonny.m5 Posted May 20, 2022 Author Share Posted May 20, 2022 @NotMyFault Thank you very much! Should I create another ticket for the bug, or just leave it? Have a nice evening. NotMyFault 1 Quote Link to comment Share on other sites More sharing options...
NotMyFault Posted May 20, 2022 Share Posted May 20, 2022 Yes, would make sense to file this as bug. But it is a kind of grey area, Affinity may decide to give an error message "unsupported file format" instead of correcting the bug.

In my opinion the lack of a message and/or opening the unsupported file format is the bug.

Try ImageMagick convert 32bit.tif -define exr:color-type=Y -compress zip 32bitY.exr produces an identical view to opening the original in CS2, it's slightly different from NotMyFault's 32bitY.exr Quote Microsoft Windows 11 Home, Intel i7-1360P 2.20 GHz, 32 GB RAM, 1TB SSD, Intel Iris Xe Affinity Photo - 24/05/20, Affinity Publisher - 06/12/20, KTM Superduke - 27/09/10 Link to comment Share on other sites More sharing options...
