Introduction

A graphical context to draw.

Usage

Create a ImageContext

To create a ImageContext, you need to provide the format of color pixel of the context. You can use the predifined color pixel or custom color pixel. The custom color pixel must be plain old data structure.

let context = ImageContext<ARGB32ColorPixel>(width: 100, height: 100, colorSpace: .sRGB)

2D rendering

Filling color with shape

let ellipse = Shape(ellipseIn: Rect(x: 10, y: 35, width: 55, height: 55))

context.draw(shape: ellipse, winding: .nonZero, color: RGBColorModel(red: 247/255, green: 217/255, blue: 12/255))

Stroking with shape

context.draw(shape: ellipse, stroke: Stroke(width: 1, cap: .round, join: .round, color: RGBColorModel()))
