Another TinyVG image parser & renderer in Rust

A library/tool to load/save binary .tvg file, rendering to .png file powered by tiny-skia, parsing from .svg file powered by usvg, with least external dependencies, simple and concise Rust code.

TinyVG textual representation (.tvgt) is only for debugging/development purposes which can be easily achieved with #[derive(Debug)] and println!("{:?}, commands) or dbg!(commands) in Rust.

Binding Blend2D rendering engine

Build controlled by feature "b2d".

    (cd 3rdparty && ./layout.sh)    # just run once

    cargo r -F b2d -- <path-to-svg/tvg> [<path-to-tvg/png>]

A built-in Rust binding for Blend2D, simpler than outdated blend2d-rs.

Binding GPAC/EVG 2D rendering engine

Build controlled by feature "evg".

    (cd 3rdparty && ./layout.sh)    # just run once

    cargo r -F evg -- <path-to-svg/tvg> [<path-to-tvg/png>]

Built-in seems the only one Rust binding in public for GPAC/EVG.

A SVG Renderer/Viewer powered by Femtovg

Build controlled by feature "nvg".

    cargo r -F nvg --bin nanovg -- <path-to-svg>

Refer to the SVG example in Femotovg, updated, rewritten and optimized the code, added Drag & Drop support.

Another SVG/TinyVG Viewer based on HTML5/Web 2D Canvas API

Run the following command in the wcnvs sub-crate/project to start the Dioxus dev server:
