GIF Coder for Swift

A lightweight LZW encoder and decoder for animated GIFs written in pure Swift, thus running on any platform, including Linux.

Example

// Create a new GIF
var gif = GIF(width: 300, height: 300)

// Add some frames for the animation
for i in 0..<20 {
    let image = try CairoImage(pngFilePath: "frame\(i).png")
    gif.frames.append(.init(image: image, delayTime: 100))
}

// Encode the GIF to a byte buffer
let data = try gif.encoded()

System Dependencies

• Swift 5.7+
• Cairo, see swift-graphics
