Examples
var info = new SKImageInfo(256, 256);
using (var surface = SKSurface.Create(info)) {
SKCanvas canvas = surface.Canvas;
canvas.Clear(SKColors.White);
// create the shader
var colors = new SKColor[] {
new SKColor(0, 0, 255),
new SKColor(0, 255, 0)
};
var shader = SKShader.CreateLinearGradient(
new SKPoint(0, 0),
new SKPoint(255, 255),
colors,
null,
SKShaderTileMode.Clamp);
// use the shader
var paint = new SKPaint {
Shader = shader
};
canvas.DrawPaint(paint);
}
The example above produces the following:
