WebP and AVIF image support

[Michael Strauß]

> For example, our application needs to display icons for Minecraft mods, modpacks, and other content sourced from Modrinth, and the vast majority of these icons are in WebP format. To work around this, we currently have to bundle TwelveMonkeys into our program, decode the images to BufferedImage, and then convert them to javafx.scene.image.Image. This approach significantly increases the size of our application, adds considerable performance overhead, does not support animated WebP, and even has a color-shift bug when decoding lossy-compressed WebP images.

I noticed that the javafx.web module already depends on libwebp during its build, yet this dependency is not utilized for javafx.scene.image.Image decoding—which is honestly a bit of a shame. We sincerely hope that JavaFX can provide native support for these formats.


There's no need for your workaround. If you have TwelveMonkeys bundled
with your application, JavaFX can read all of the supported images
"natively" without manually converting to BufferedImage first. You
just specify the WebP file in the constructor of Image.

What's true is that this doesn't work for animated images.
