piet VS Skia

You can even check https://github.com/linebender/piet and https://github.com/RazrFalcon/tiny-skia. They are pure rust libraries. Skia as a whole is a big binary to add.

First, at the deepest level, we are moving away from Piet, which is a cross-platform 2D graphics abstraction. Under the hood it uses whatever the standard OS API is. Instead we will be using Vello which we have been building as a research project for years already. It is starting to near its v0.1, which is very exciting. Fundamentally it is a novel GPU accelerated 2D rendering engine with a strong focus on performance. It is not ready for benchmarks yet, but we're confident it will deliver. If you're curious, you can check out the Vello roadmap for 2023.

you can use piet, although that is more of an abstraction over existing, platform-dependent libraries. So not really pure rust, but definitely cross-platform.

Piet is the backend for the Druid UI framework. It is indeed cross-platform. The SVG backend looks like it would work without an OS, but I'm not sure the value of a GUI toolkit without an OS anyway :)

Piet can render text. You can use Piet_common with the BitMapTarget to generate images Here is an example.

Piet (https://github.com/linebender/piet) should work.

So the 3 I'm looking at right now are 1. druid 1. piet 1. bevy

It relies on piet 2D graphic library; on Linux that means GTK/Cairo 2D primitives

Actually, that's not entirely accurate. The lottie-web library itself doesn't support rendering to WebGL. However, there is a package called canvaskit-wasm that wraps Skia (a graphics engine) with WebAssembly (wasm). This package includes a module called skottie which supports rendering animations into a WebGL surface. However, there is a drawback with this approach: using wasm requires loading a relatively large package, and it's uncertain whether all features are supported correctly, as the official compatibility table that tracks lottie support on different platforms does not include skottie.

Skia is pretty great if you can get it running.

The imgs are mainly used by Tencent QQ and Baidu Tieba users. QQ and Tieba compress imgs by default, so the popular imgs (in China we call them "屌图" or "表情包") would be compressed million of times during the spreading, causing the super low quality. These APPs on Android are using Skia for image processing, which suffering from a legendary bug: result would be more green. The bug was fixed in 2016: https://github.com/google/skia/commit/c7d01d3e1d3621907c27b283fb7f8b6e177c629d

There’s also Skia by Google. Used by Android and Google Chrome.
