Maik 2214468 2 aacid 2023-03-06 22:33:08 +0000 Mirco you did some work on the xcf code. Would you have some time to look at this? 2214569 3 metzpinguin 2023-03-07 06:49:31 +0000 Since we got the same bug report about supporting float16 (half float) for our TIFF loader, here maybe the function to read and convert float16 as a help. The basic function comes from the Adobe DNG-SDK. https://invent.kde.org/graphics/digikam/-/blob/master/core/dplugins/dimg/tiff/dimgtiffloader_load.cpp#L951 Maik 2214571 4 mircomir 2023-03-07 06:53:31 +0000 (In reply to Albert Astals Cid from comment #2) > Mirco you did some work on the xcf code. > > Would you have some time to look at this? The Qt plugin supports xcf specs up to version 11 and the files in question are version 12. We have a merge request to add this functionality but it has other problems and consequently it breaks the tests. I tested the MR (https://invent.kde.org/frameworks/kimageformats/-/merge_requests/108) and some generated images are not correct (mainly related to alpha blending) . Adding support to version 12 requires in-depth knowledge of the XCF format which I don't have. 2214572 5 mircomir 2023-03-07 06:55:12 +0000 (In reply to Maik Qualmann from comment #3) > Since we got the same bug report about supporting float16 (half float) for > our TIFF loader, here maybe the function to read and convert float16 as a > help.

Maik 2219494 7 leoutation 2023-03-31 14:15:48 +0000 I see KImageFormats works fine with .psd proprietary Adobe format. This leads people to think that it is difficult to work professionally with free image editing software, Gimp ... 2219540 8 mircomir 2023-03-31 17:21:46 +0000 (In reply to maderios from comment #7) > I see KImageFormats works fine with .psd proprietary Adobe format. Nobody has it with GIMP. The PSD plugin works well because I work in large format digital printing and everyone uses Photoshop. I maintain two PSD readers: the one for the company I work for (it's not a qt plugin) and the KDE Qt plugin (for fun). I would also like to fix the XCF plugin but no promises. For now, I've only looked at the specs. 2234630 9 leoutation 2023-06-04 10:07:48 +0000 A hope that seems dead :( https://invent.kde.org/frameworks/kimageformats/-/merge_requests/108#note_693028 2246418 10 mircomir 2023-08-14 08:43:05 +0000 (In reply to maderios from comment #9) > A hope that seems dead :( > https://invent.kde.org/frameworks/kimageformats/-/merge_requests/ > 108#note_693028 I made some changes to Martin's code to fix the most obvious problems and made a new MR (https://invent.kde.org/frameworks/kimageformats/-/merge_requests/166).
