Describe the bug
All of half a dozen or so DNG files I tested display in nomacs with a bright pink color cast (much stronger than can be explained by something like nomacs ignoring embedded white balance information). The DNG image displays correctly in Lightroom, Darktable, gThumb, and RawTherapee. TIFF images created using dcraw also do not have this problem.
Steps to reproduce the behavior:
Convert a Canon RAW file (.CR2) to Adobe's DNG format (Camera Raw version 11.2) using Adobe tools (e.g. Lightroom). Lossy DNG mode is not enabled.
Open the image in nomacs.
The image displays correctly.
Desktop (please complete the following information):
OS: Arch Linux
Linux kernel version 5.0.13
nomacs version 3.12
Issues with pink images have sometimes occurred with other raw files and other programs, as a web search will quickly reveal. However, I haven't been able to find a common thread to all of them. At least in this case, other image viewers and raw file editors are displaying the image correctly.
Some additional information: I've since found that for a certain subset of raw files, RawTherapee and other dcraw based programs show the same bug. The difference is that every DNG file I've tested with nomacs has shown this problem. Beep6581/RawTherapee#4695
I still have this problem with the last nomacs stable and beta builds. I'm using Windows 10. It happens with all the RAW (.dng) files from my OnePlus 7T. In the others apps they looks as they have to.
Maybe this fix is not implemented yet? Maybe this fix doesn't work with all RAW files?
Thank you for your work and sorry for my poor english.
