# GIMP — Free Open Source Image Editor and Manipulation Program

> GIMP (GNU Image Manipulation Program) is a free, open-source raster image editor for photo retouching, image composition, and graphic design. It runs on Linux, macOS, and Windows, offering layers, masks, filters, and extensibility through Python and Script-Fu plugins.

## Install

Save as a script file and run:

# GIMP — Free Open Source Image Editor and Manipulation Program

## Quick Use
```bash
# Install
sudo apt install gimp           # Debian/Ubuntu
brew install --cask gimp        # macOS
flatpak install flathub org.gimp.GIMP   # Flatpak
# Launch
gimp
# Batch process via Script-Fu
gimp -i -b '(gimp-image-list)' -b '(gimp-quit 0)'
```

## Introduction
GIMP has been a cornerstone of free software since 1996, providing a capable image editor for tasks ranging from quick photo fixes to complex multi-layer compositions. It serves as the primary free alternative to Adobe Photoshop for raster image editing, with a large plugin ecosystem and active development community.

## What GIMP Does
- Edits raster images with full support for layers, channels, masks, and blending modes
- Retouches photos with tools for clone stamping, healing, dodge/burn, and perspective correction
- Supports dozens of file formats including PSD, TIFF, PNG, JPEG, WebP, and its native XCF
- Extends functionality through Script-Fu (Scheme), Python-Fu, and hundreds of community plugins
- Provides color management with ICC profile support for print and web workflows

## Architecture Overview
GIMP is written in C using the GTK toolkit (which was originally created for GIMP). The core uses a tile-based image processing engine with GEGL (Generic Graphics Library) for non-destructive, high-bit-depth operations. Plugins communicate via a well-defined API supporting Script-Fu and Python. The architecture allows multi-threaded filter processing and hardware-accelerated rendering through GEGL's OpenCL backend.

## Self-Hosting & Configuration
- Install from package managers or download from gimp.org for the latest stable release
- Customize the interface layout by docking and rearranging tool windows via Windows > Dockable Dialogs
- Install third-party plugins and scripts by placing them in ~/.config/GIMP/2.10/plug-ins/ or scripts/
- Configure color management profiles in Edit > Preferences > Color Management for accurate display
- Use batch mode (gimp -i -b) for automated image processing in scripts and CI pipelines

## Key Features
- Non-destructive editing via GEGL-based filters with on-canvas previews
- Customizable tool presets and keyboard shortcuts for optimized workflows
- Path tool for vector-based selections and shapes within the raster editor
- Animation support through layer-based frames and the Animation Playback filter
- Extensive file format support including raw camera files via darktable/RawTherapee integration

## Comparison with Similar Tools
- **Adobe Photoshop** — industry standard with more advanced features, but requires a paid subscription
- **Krita** — focused on digital painting with a superior brush engine; GIMP is better for photo editing
- **Photopea** — browser-based Photoshop alternative; GIMP offers deeper plugin support and offline use
- **Paint.NET** — Windows-only with a simpler interface; GIMP provides more professional-grade tools cross-platform

## FAQ
**Q: Can GIMP replace Photoshop?**
A: For many workflows, yes. GIMP handles photo editing, compositing, and design. Advanced features like non-destructive adjustment layers are improving with GEGL integration.

**Q: Does GIMP support PSD files?**
A: Yes. GIMP can open and export PSD files, preserving layers and many layer effects.

**Q: Can I use GIMP for batch processing?**
A: Yes. Use Script-Fu or Python-Fu in batch mode (gimp -i -b) to process images without the GUI.

**Q: Is GIMP hard to learn?**
A: The interface differs from Photoshop, but extensive documentation and tutorials are available. Version 3.0 brings a modernized UI.
