Work-in-progress Swift bindings for Blend2D. This project makes use of the original source code of Blend2D and is in no way associated or supported by Blend2D.

For a brief report of what APIs are available in Swift, please check the status page.


Xcode 13.0 / Swift 5.4.3

Sample usage

Taken from sample1 from the samples library.

let img = BLImage(width: 480, height: 480, format: .prgb32)

// Attach a rendering context into `img`.
let ctx = BLContext(image: img)!

// Clear the image.
ctx.compOp = .sourceCopy

// Fill some path.
let path = BLPath()

path.moveTo(x: 26, y: 31)
path.cubicTo(x1: 642, y1: 132, x2: 587, y2: -136, x3: 25, y3: 464)
path.cubicTo(x1: 882, y1: 404, x2: 144, y2: 267, x3: 27, y3: 31)

ctx.compOp = .sourceOver

// Detach the rendering context from `img`.

// Let's use some built-in codecs provided by Blend2D.
let codec = BLImageCodec(builtInCodec: .bmp)

try img.writeToFile("bl-getting-started-1.bmp", codec: codec)

This should create an image in the current working directory like so:
