ThorVG: lightweight vector graphics engine with Lottie and SVG support for apps and embedded devices

What it supplies: Thor Vector Graphics is described as a production-ready vector graphics engine for interactive apps and creative tools, combining high performance with lightweight efficiency. It supports shapes, gradients, strokes, masking, text, SVG and bitmap images, effects, and Lottie and GIF playback. Useful for: - Render vector shapes and SVG in apps, including headless server-side or offline rendering. - Play Lottie animations with a build that can be as small as a compact playback library. - Convert SVG to PNG and Lottie to GIF with the CLI tools. - Check how Lottie and vector assets render using ThorVG View in the browser. First action: - Install Meson and ninja, then run meson setup builddir and ninja -C builddir install. - For a compact Lottie build, configure with -Dloaders set to lottie, or all. - Try the web playground or ThorVG View before building. Prerequisites and limits: - Building uses Meson and ninja, with Visual Studio and Xcode back ends available. - The code base is C++ with SIMD acceleration through AVX2 on x86 and NEON on ARM. - Render backends are CPU/SIMD software, OpenGL/ES, WebGL and WebGPU. - Partial rendering helps little, and may add overhead, when nearly all objects change every frame. - Performance and binary-size figures are the README's own and were not measured here.

Assets you render carry their own rights. Written from the README text only. Statements are as the README gives them; nothing was built or run and no file was rendered.
