JPG has huge generation loss, that's why I always choose PNG for my private files or use a program which can handle raw.
We don't educate the users currently about the right choice of file formats, so they upload their files in the format which is available for them. Taking JPG directly from a camera which does not support raw is fine, but we should take the step and convert this initial JPG to a lossless format because: Every user which edit those file will take the JPG and save a "new version" in the same format because they want to preserve the filename. If we would convert the JPG to PNG or FLIF, this step would be lossless while we don't control anything on the user side. This was my point. > Even worse: FLIF is not even needed for the scenario you describe. We could > just convert all JPEG to PNG. But this will not happen for the reasons > collected in this thread. FLIF is better instead of PNG because it supports animations, is faster to decode, use less disk space. Also saving it interlaced does not increase the file size significantly and we just need to save one file instead of at least 3 different versions of the same file: the thumbnail, the zoomed version, and the original file. With FLIF this file would be always the same while the browser would limit the amount of data required for the display size. > Sure. Go and encourage people to upload RAW. That's very much welcome.

Well, yeah, I tried several times in the past ... and no, my RAW-Format is still not supported: "Bei der Übertragung gab es einen Fehler Auf diesem Wiki sind Dateien mit der Endung „.NEF“ nicht zulässig." Means .NEF is not supported. "Bei der Übertragung gab es einen Fehler Auf diesem Wiki sind Dateien mit der Endung „.DNG“ nicht zulässig." Means, .DNG is not supported. With FLIF we could simply accept all which does have a free decoder and convert them to FLIF. Which would 'free' the file format. :) > Even including the one you aim for: What you want is to allow people to > download an image, open, edit and save it without ever thinking about the > file format. FLIF can not do that, yet. Since we could easily convert the FLIF on export to PNG and any new version could be uploaded in PNG an internally converted to FLIF to reduce the disk space requirements as well. I hope GIMP and Gnome will support FLIF soon. Thanks a lot for your critic, I appreciate our discussion. :) Best regards Ruben _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
