Simp

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

Goals

• Support of as many image formats as possible.
• 60 Hz. Avoid blocking for more than 16ms.
• Flicker free redrawing.
• Smooth resizing.
• Always use GPU-acceleration where possible.
• Desktop OS support.
• Basic image manipulation.

Non Goals

• Powerful image manipulation (I am not making the next photoshop)
• Web/Mobile platform support.

Supported Platforms

| OS | Support | | ------- | :-----: | | Windows | ✅ | | Linux | ✅ | | MacOS | 🆗 |

✅ = Tested and working
🆗 = Untested but should work with minimal changes

Supported Codecs

| 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) |

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

Cargo

shell cargo install simp

Latest from github

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