Add support for DNG export

[dennispcarne-ui]

Question or suggestion

It would be useful if OpenPhotoAI was able to export a .dng raw file to retain maximum quality for subsequent photo processing steps.

I did some digging because I never worked exporting images to DNG before, and I found 2 things:

• The official Adobe SDK to create DNG doesn't support Linux, so I can't use that since I want to add features in the app that are available in all OSes.
• There's an open source version of this SDK that supposedly supports Linux, but it was last updated 11 years ago and it's very hard to use.

I will keep this ticket open however, because I'm planning to rewrite the project using Rust, that has a library that supports encoding DNG files. When the project migration to Rust is done I can add DNG support, but it will probably take a long time.

No problems - Thanks. I moved to linux last year as my main system since MS dropped support for win10 and I was unable to install win 11 on that particular laptop. At that stage I installed linux mint and have not looked back. I subsequently purchased a more powerful mini PC and again installe linux mint. I have been able to replace the main apps I used on windows with equivalents or those that will run under the wine app. Topaz photo AI is the last on my list so I was pleased to find your OpenPhotoAI software. I will continue to look out for updates and provide feedback where I can. I will use Topaz for now on my win 11 laptop to generate dng files when processing my bird photos. The need for Topaz PhotoAI is the only real reason for maintaining my win 11 machine. Good luck with the Rust project in due course. There is no real hurry from my side. Regards, Dennis
