Prior to the installing the additional image processing packages, Megapixels produced both .dng and .tiff files. Now I only get .dng (no .jpg). Perhaps there's another reason for the change in bahavior. I last took photos about a week ago and .tiff files were produced.
I tried "sudo apt purge dcraw imagemagick" but no luck getting automatic .tiff conversion back.
Any ideas or suggestions? Thanks!
i get only .dng files too! before that it saved to .dng and .jpg files.. i think the change happend at the moment where they introduced the qr-code reading feature
In an attempt to learn / debug the behavior of the script and its interaction with Megapixels output, I renamed some .dng files in my Pictures folder to 1.dng, 2.dng, 3.dng, etc. Then I issued the command.
"/usr/share/megapixels/postprocess.sh /home/mobian/Pictures test"
and the result was it deleted my entire Pictures subdirectory with all my (wanted) pictures in it!
I guess I should have studied the script code before trying to use it manually!
I think I'll just run dcraw from the terminal to do my conversions manually for now.
Okay, I got my .tiff output back. It turns out that I didn't purge / remove imagemagick when I thought I had.
Once I actually removed imagemagick (while retaining dcraw), the .tiff files were automatically produced by the megapixels postprocess.sh script again. I suspect that when imagemagick is installed, postprocess.sh tries to produce a .jpg from the dcraw .tiff but the conversion is failing for some reason and postprocess.sh deletes the .tiff. file.
I don't have time to study the script and figure out what is happening now but It would probably take me far less time to find a lightweight .tiff to .jpg converter and write my own script. Ever since I got my PinePhone late last year, I've been copying the .tiff files over to my MX Linux laptop and using gimp to convert to other compressed formats, when desired (because .tiff is huge, of course).
Maybe megapixels dev, Martijn Braam, would respond to a bug report, but I haven't found where to file one. There's more info here:
