what's the problem?
In addition to what others wrote: There is now a lossless WebP variant. I'm still unsure about their lossy format, but the lossless codec can create smaller pictures than PNG, and that's mildly interesting.xnview wrote:what's the problem?

If you open XnViewShellExt64.dll in text editor there is plenty of text strings "webp", "WebP" inside, so maybe it has functions to process them, I don't know. When extension is registered, it is registered in section ContextMenuHandlers for all types of files (in HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers\IXnView and HKEY_LOCAL_MACHINE\SOFTWARE\Classes\*\shellex\ContextMenuHandlers\IXnView keys of registry). I'm suspecting it decides on its own when to show itself, and probaly currently it doesn't recognize webp as type it can handle, which doesn't mean it really can't. But I don't know for sure.omniplex wrote:Back to XnView, apparently XnViewShellExt64.dll 3.5.1 (February 2015) is still up to date, and still does not support WebP, or if it supports WebP please tell me how to arrange this in a Windows 7 registry.
Makes sense, and that could be an ordinary bug. FWIW there's a RIFF string in the XnViewShellExt64 binary, but no VP8 for WEBPVP8 or WEBPVP8L.Mixer wrote: it doesn't recognize webp as type it can handle, which doesn't mean it really can't.
An interesting FLIF-thread, thanks for the link. XnView/Plugins/WebP.dll was apparently created in January 2015, this could be libwebp 0.4.2. The latest libwebp 0.5.0 was released in December 2015. The WIC codec 0.19 is three years old.heimaki wrote:http://encode.ru/threads/2321-FLIF-Free-Lossless-Image-Format?p=47877&viewfull=1#post47877
i have a feeling, in xnview we still have an old webp lib. i compiled the newest one myself, but xnview simply crashed with that one.

it is not obvious at all what to do if one wants to save lossless, as far as i can tell, we need to set quality to 100% to get this, everything below is lossy.
it would make much more sense to have a seperate (radio)button for lossless.
