Simp

Simp is a fast and simple GPU-accelerated image manipulation program.

Goals

OS	Support
Windows	Primary development platform and the most well tested.
Linux	Arch + Kde is semi regularly tested and it always compiles for ubuntu in cli.
MacOS	MacOS compiles but is not well tested.

Format	Decoding	Encoding
PNG	✅	✅
JPEG	✅ Baseline and progressive	✅ Baseline
GIF	✅	✅
BMP	✅	✅
ICO	✅	✅
TIFF	✅ Baseline(no fax support) + LZW + PackBits	✅
WebP	✅ Converted to Rgba8	✅ Lossless only
AVIF	🚧 Only 8-bit (1)	❌
PNM	✅ PBM, PGM, PPM, standard PAM	❌
DDS	✅ DXT1, DXT3, DXT5	❌
TGA	✅	✅
farbfeld	✅	✅
SVG	✅ Rastarized at 96 dpi (2)	❌
PSD	✅	❌
Raw	✅ Support from rawloader (3)	❌
HEIF/HEIC	❌ (4)	❌
OpenEXR	✅ Rgb32F, Rgba32F (no dwa compression)	✅ Rgb32F, Rgba32F (no dwa compression)

Building with AVIF support requires the C library dav1d and is therefore not enabled by default.
SVGs are rastarized because Simp is primarly 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.

System dependencies are only required at compile time.

sudo apt-get install libgtk-3-dev libxcb-render0-dev libxcb-shape0-dev libxcb-xfixes0-dev libspeechd-dev libxkbcommon-dev libssl-dev

The dav1d library is required to be installed to build with AVIF support.

cargo install simp --locked

cargo install --git https://github.com/Kl4rry/simp --locked

The latest bulid 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.

It's an acronym (S)imple (i)mage (m)anipulation (p)rogram.
