- Building with AVIF support requires the C library dav1d and is therefore not enabled by default.
- SVGs are rastarized because Simp is primarily a bitmap image editor.
- Most common cameras are supported but the colors may look weird because the standard curve may not fit all images.
- HEIF/HEIC is not supported because it is currently very hard to link libheif on windows.

pacman -S dav1dpacman -S git rust cargo-about nasm clangcargo install simp --lockedparu -S simpA pre-compiled binary is available from the official repositories. To install it, simply run:
pkgin install simp
cargo install --git https://github.com/Kl4rry/simp --lockedThe latest build is very likely buggy and unfinished. You can always also just grab the latest binary from actions build artifacts.
Just download the exe from the releases tab. No actual installation is required.
