Can't open webP images in XnViewMP 0.93

Post by joomlafab » Fri Jun 07, 2019 5:19 am

Hi,

I'm trying to open webP images (static images, not animated), in XnViewMP 0.93 64bits on Win10 64.

My "%PROGRAMFILES%\XnViewMP\plugins" folder contains 2dll : libwebp.dll (607 Ko) and libwebpmux.dll (160 Ko)

I can see the thumbnails images when I browse the folder with XnViewMp, but I can't enlarge them. The "Open" (Ctrl+O) and Full screen (F11) context menus are disabled/grayed. If I double-click some WebP images, they open in Chrome and I can see them though. I tried to set WnViewMp as default program to open WebP images, but then when I double-click a WebP image, it opens a news XnviewMp browser with thumbnails again, no full size image.

Am I doing something wrong ?

However xnViewMP was telling my version was up to date, I found here that there is a newer 0.93.1 version, that adresses some WebP issues. I updated, but it is still the same. Impossible to open/full screen webP images.

Hi Pierre,

thanks for your anwser (and for your great work with Xnview softs). I actually already replied myself that the problem probably comes from my photoshop plugin, but my reply wasn't accepted for some reason.

I actually found out that when I download some webP sample from https://developers.google.com/speed/webp/gallery1, they have a few exif data, and they open fine in XnViewMP. However, the webP files produced by my photoshop plugin (http://telegraphics.com.au/sw/product/WebPFormat ) don't seem to have any exif data and they don't open in XNViewMP. They open fine in firefox, and sometimes fine sometimes not in chrome...
Sorry for wasting your time, the faulty photoshop plugin is probably the reason of this.

Just in case, you'll find a sample file attached. I had to zip the file since this forum doesn't accept webP file attachements.

the WEBP tools can't decode it too, the file is corrupt (premature end of file)

Are animated webp files even supported? XNView refuses to open them, but they work just fine in internet browser.
