1 year ago Interesting, thanks for calling this out. I added the ability to encode uncompressed in the lib already, so this is just a matter of adding the ability to tweak options on save.
I'd like Luna Paint to export the most compatible images by default but I'm very surprised Affinity doesn't do RLE correctly 🤔, disabling compression by default would be a shame. Alpha is a little tricky/ambiguous so I can understand the macOS viewer one more.
Luna saves TGA in "Runlength encoded color-mapped images" (across specification http://www.paulbourke.net/dataformats/tga/, section "Data Type field"). Some editors don't support this format fully. For example:
Can you add to Luna dialog with variations of saving format (for TGA usually it includes selecting RLE compression and origin)? For me very important "Uncompressed, RGB images".
