  • Anyone want to speed up a PNG decoder?

    I recently wrote a png-decoder for use in fontdue to parse emoji PNGs in a no_std context. I haven't yet put any effort into optimization, and from some basic benchmarks it seems the Wuffs implementation runs twice as fast.

    Just sent a pull request to fix that issue (https://github.com/bschwind/png-decoder/pull/11)
  • The Fastest, Safest PNG Decoder in the World

    I recently wrote a Rust PNG decoder mostly for use in no_std contexts, and it was motivated out of wanting to decode emoji for a font rasterizer.

    I didn't really put any effort into optimizing it yet, though it does use miniz_oxide and it decompresses the entire image at once instead of per-scanline.

    I'm curious if it is at all competitive with the Wuffs decoder, I'm guessing probably not because I haven't put any effort into using SIMD.

    But overall the implementation was pretty straightforward, I just read the RFC and wrote it out over a few weeks. One quirk of my library currently is it always returns an RGBA buffer, instead of potentially letting you save memory on a grayscale or RGB image.
