I installed DK on my Linux Mint desktop as a Flatpak. RawTherapee is installed as an Appimage. I went to ‘Open With’ in DK and selected RT, I also associated APW files to RT but when I select RT from the pull down nothing happens.
Is it a sandboxed Flatpak thing?
edit: Strange, I added the path to my USB SSD in Flatseal for DK but it made no difference. That was the problem I had with Darktable (also Flatpak) and it opened up.
You need to start rt with flatpak spawn as the first part of the command.
How would I use that in the DK GUI to open an image in RT or would I need to use terminal?
Are your files Sony lossless compressed? They are not yet supported by RT. You can try ART as an alternative.
They’re ARW files so shouldn’t they be OK? The same files open in Darktable.
edit: The camera is an old Sony a7.
I guess in the GUI. Running flatpak spawn allows flatpak to execute things outside the sandbox.
I have no experience doing this with digikam tho.
Hmmm, not sure how I’d do that and it might not be worth it if I have to do it every time.
Thanks though.
You’d set it as part of the command to open RT.
ARW has at least three variants (there may be some very outdated ones that predate the current three)
Lossy compressed
Uncompressed
Lossless compressed
Lossless compressed is new and not supported by RT and a few other software packages
You say “old” - how old? Only the A7M4 supports lossless compressed out of the non-R/non-S families. Only the newest Sonys (last 2-3 years at this point, units with the new BIONZ XR) support lossless compressed. Anything older works fine in RT.
@thusband Darktable and ART can open Sony lossless compressed files because they switched to using LibRaw. RT switch to LibRaw is in progress, but not finished yet.
That explains that I guess. Thanks, I’ll stick with Darktable.
