It's in XnView Classic, but not in MP (yet) - could it be added, too, pretty please with sugar on it ?
It's such a nice format and is really ahead of the lossless competition. Plus it's oss and (supposed to be) patent free, thus supporting it would be a show of faith itself. And as it's actively developed so the dev should be open to communication (unlike bpg or xr).
... so I downloaded the alledged "working" flif plugin (from http://www.encode.ru/threads/2321?p=478 ... #post47861) and put it into my respective x86 and x64 XnViewMP plugin folders. And, who would have guessed, I now can *save* a .flif file. Alas, I cannot *load* it, it doesn't show up in the file list and if I try to force to read this very .flif via command line it's "File can't be loaded".
In any case, this flif plugin is outdated - it needs to be recompiled with the new and incompatible 0.2 flif code... ImageMagick just updated, too. So for reference I'm attaching a working 0.2 flif sample, only if you're able to load this one all's working.

I did my tests with MP v0.83 as well as Classic v2.36 and the beta of v2.37. No matter which libflif.dll I use — the one provided by Pierre (flif.zip) or those available from encode.ru (FLIF_ca72a18.rar): Writing FLIFs seems to work, reading doesn't.
Always nice not to be the only one being lost ... let's hope some dev figures out why reading .flif doesn't work, I have no idea what api XnView expects from a dll.
Edit 2: The other forum has the solution - the official x86 dll works in Classic and MP, but the x64 dll fails with MP ... https://github.com/FLIF-hub/FLIF/releases
Great to see FLIF support. I hope it gets fully implemented including options for tweaking settings and lossy format. This format has great potential, afaik it beats every other format in every aspect.

Not quite, the author himself states that other formats are better for lossy photo compression than lossy flif. The advantage of flif ist great 100% lossless mode, no generation loss when lossy, and it doesn't care that much for image content while other formats are tuned for photgraphy and not for example diagrams.
However, for one-time compression of photographic content, bpg (hevc base) is the best atm, but burdened by patents ... webp (vp8-based) has a very competent lossy-lossless mode and will get supercharged once it's upgraded to av1 base.
FLIF files will not load for me. I have downloaded the latest x64.zip & extracted. When double clicking a "flif" (not zip) file in MP, a blank gray screen is loaded. When trying "file-open", i get an "error, file can't be loaded" popup window. Is there something special that needs done?

Is that part of the latest release? Am I supposed to have to download something else? FLIF is checked in the "filetype" settings screen. How would I verify the plugins & libflif.dll are installed?
?
