SwiftLibgd is a Swift wrapper for libgd, providing server-side image manipulation where Core Graphics isn’t available. Built for Swift 6.2+.
It allows you to:
- Load and save PNG/JPEG images.
- Create, resize, and crop images.
- Draw lines, shapes (ellipses, rectangles), and images.
- Read and write individual pixels.
- Flood fill colors.
- Flip images horizontally or vertically.
- Apply basic effects: pixelate, blur, colorize, desaturate.
SwiftLibgd handles GD resources automatically, freeing memory when images are destroyed.
- Install the GD library on your system:
- macOS: Install Homebrew, then run:
brew install gd
- Linux: Run as root:
apt-get install libgd-dev
- Add SwiftLibgd to your
Package.swift:
.package(url: "https://github.com/brillcp/swiftlibgd.git", from: "0.1.2")
- Include SwiftLibgd in your target dependencies. SwiftLibgd has a single Swift dependency: Cgd, which wraps the underlying GD library.
