SwiftUI Skia

The swiftui-skia is a skia based 2d graphics SwiftUI rendering library. It is based on Rust to implement software rasterization to perform rendering. It performs better in cross-platform adaptability than hardware rasterization, however it is still an experimental project. And it's based entirely on SwiftUI syntax.

基于 Skia 的 2D 图形 SwiftUI 渲染库 —— 使用 Rust 语言实现纯软件光栅化渲染，相比原生光栅化具有更好的跨平台适应性，不过目前仍然是一个实验项目；此外使用层面完全基于 SwiftUI 语法。

Usage

import SwiftUI
import SwiftUISkia

struct ContentView: View {
    var body: some View {
        SwiftUISkia.Surface(width: 360, height: 360) {
            SwiftUISkia.Rect(x: 10, y: 220, width: 30, height: 30, style: "fill", color: "cyan") {}
            SwiftUISkia.Image(image: "https://raw.githubusercontent.com/rustq/swiftui-skia/main/examples/first-example/first-example/Assets.xcassets/swiftui-96x96_2x.imageset/swiftui-96x96_2x.png", x: 0, y: 0, width: 64, height: 64, blur: 5, brighten: 98) {}
            SwiftUISkia.RoundRect(x: 220, y: 50, r: 10, width: 80, height: 80, style: "stroke", color: "fuchsia") {}
            SwiftUISkia.Points(points: [
                [138, 10],
                [178, 90],
                [266, 103],
                [202, 165],
                [217, 254],
                [138, 212],
                [59, 254],
                [74, 165],
                [10, 103],
                [98, 90],
                [138, 10],
            ], strokeWidth: 1, style: "fill", color: "rgba(200, 255, 0, 0.7)") {}
            SwiftUISkia.Circle(cx: 200, cy: 220, r: 70, style: "stroke", color: "violet") {}
            SwiftUISkia.Circle(cx: 200, cy: 220, r: 50, style: "fill", color: "violet") {}
            SwiftUISkia.Text(text: "Hello SwiftUI Skia!",x: 80, y: 0, fontSize: 16, color: "black", maxWidth: 60) {}
        }
    }
}
