webp-pixbuf-loader VS vipsdisp

EOG supports webp if you have webp-pixbuf-loader installed.

In the log messages bwrap was complaining it can't find /usr/local/bin/gdk-pixbuf-thumbnailer, which is correct, because in Ubuntu it is placed in /usr/bin by default. Looks like it may be somehow related to this bug https://github.com/aruiz/webp-pixbuf-loader/issues/29.

You need the webp pixbuf loader in order for that work.

Sadly no. You can find it in various PPAs, or compile it from source.

If you're using Eye Of GNOME, just add webp-pixbuf-loader.

Well, the day before yesterday I decided I needed webp image viewer on my Ubuntu Mate, so I have found I had to install https://github.com/aruiz/webp-pixbuf-loader

You need to install webp-pixbuf-loader: https://github.com/aruiz/webp-pixbuf-loader

See if your distribution has a webp-pixbuf-loader package.

if you're using linux (which it doesn't seem so) there's also vispdisp https://github.com/jcupitt/vipsdisp which is based on https://github.com/libvips/libvips which will likely take over how images are decoded in the future for everything, at least methodology wise.

Yes, I based it partly on visual programming system that Canon made back in the 90s. I loved the interactive development, but I really disliked that style of visual programming. Lines between boxes seems very hard to reason about, to me.

nip2 tries to do something similar, but using expressions, like a spreadsheet. Unlike graphical plugs and wires, expressions allow things like copy-paste, smart refactoring, referential transparency, and progressive rewriting.

nip2 is ancient now (I finished it way back in 2002, I think). I've started a rewrite for gtk4 -- the image display window is here:

It's quite fancy -- it has a sparse pyramid of image tiles which get composited to your display by the GPU, and computed asynchronously by a libvips pipeline as you zoom and pan around. You should get a smooth 60 fps even with enormous (eg. 300,000 x 300,000 pixel) images.
