README
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A built-in Rust binding for Blend2D, simpler than outdated blend2d-rs.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:
dx serve --hot-reload
