Class BlendPaint

Namespace

Egami.Drawing

Assembly

Egami.Drawing.dll

Two paints combined pixel by pixel with a blend mode, as Skia's blend shader: Source is blended onto Destination, and the result is what this paint draws. Each part keeps its own LocalMatrix and Opacity (its blend mode, blur and dithering are not used), inside this paint's own local matrix.

Examples

LinearGradient sky = new(new Vector2(0, 0), new Vector2(0, 100), new RgbaF32(0.2f, 0.4f, 0.9f, 1), new RgbaF32(0.9f, 0.6f, 0.4f, 1));
NoisePaint clouds = NoisePaint.Fractal(0.02f, 0.05f, 4, seed: 3);

// Noise multiplied onto the gradient, then the whole paint turned to sepia.
Paint paint = new BlendPaint(sky, clouds, BlendMode.SoftLight).WithColorMatrix(ColorMatrix.Sepia(0.6f));
using (RasterCanvas<Rgba8> canvas = raster.CreateCanvas())
{
    canvas.DrawPaint(paint);
}
