tiny-skia VS resvg

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.

Looking through the source code. It looks like it's using tiny-skia for rendering.

Tiny Skia (https://github.com/RazrFalcon/tiny-skia) which is a slower Rust port of Skia and does all software rendering.

https://github.com/RazrFalcon/tiny-skia is pretty great.

I understand that this may sound harsh, but I also ported two (far bigger) codebases from C++ to Rust: rustybuzz and tiny-skia. Both of which are production -ready and not just prototypes. And mine not only do not use pointers, but also barely use unsafe in general.

Here is a real world implementation in tiny-skia: https://github.com/RazrFalcon/tiny-skia/blob/master/src/pipeline/highp.rs

How about tiny-skia?

How about tiny-skia? Almost the same performance as C, no unsafe, a lot of explicit SIMD.

Now I would love to see a universal Bezier path crate, storage + common utilities like length, point at offset, some low-level stuff, etc. So it could be used as a foundation for other crates. Currently, there is a lot of friction because each crate has its own implementation.

Nice to see tiny-skia in use.

I've seen resvg as a potential pick, but it feels huge and seems to be importing skia, which itself is a whole rendering engine. Furthermore, I have no idea if I can pass my own 2D buffer to resvg and let it draw to it.

For example, when converting vector SVG images to raster PNG images with resvg, most of the time is spent compressing the PNG image. This is a lot of wasted work if we just want to read the image instead of transferring it over the network! The fast compression mode eliminates all this wasted work, resulting in huge performance and efficiency gains.

Just as a point of reference, I have a ~75KLOC project (includes dependencies) called resvg which takes just 4s in the debug mode and 8s in the release mode to build on M1 Pro.

resvg is very fast, although the performance depends on the exact SVG you feed it - sometimes faster than librsvg, sometimes slower (although librsvg is also written in Rust now, it does use unsafe while resvg doesn't)

So I am absolutely clueless about Rust and just installed it an hour ago to use this tool called "usvg" https://github.com/RazrFalcon/resvg/tree/master/usvg

So, all you gotta do is rewrite the parsers. Funny you mention librsvg because there is a library called resvg that has a thumbnailer implementation for Windows Explorer. https://github.com/RazrFalcon/resvg
