Enum StampStyle

Namespace

Assembly

How Stamp(Path, float, float, StampStyle) places its shape along a path.

public enum StampStyle

Fields

Morph = 2

The shape is bent along the path: its x runs along the path and its y away from it, so it follows curves.

Rotate = 1

The shape is moved to each point and turned so its x axis follows the path.

Translate = 0

The shape is moved to each point, upright.

Examples

// A hand-drawn chart line: jittered the same way on every run, then its corners rounded.
Path data = Path.Polygon([new(10, 80), new(50, 30), new(90, 60), new(130, 20), new(170, 50)], close: false);
PathEffect sketchy = PathEffect.Jitter(segmentLength: 6, deviation: 1.5f, seed: 7).Then(PathEffect.Corner(3));
using Raster<Rgba8> chart = Raster.Create(180, 100, Rgba8.White);
using (RasterCanvas<Rgba8> canvas = chart.CreateCanvas())
{
    canvas.StrokePath(data, new Stroke(2) { Effect = sketchy }, new Rgba8(40, 40, 40, 255));

    // Dots along the line, and hatching inside a circle.
    canvas.FillPath(data.Apply(PathEffect.Stamp(Path.Circle(Vector2.Zero, 2), advance: 12, style: StampStyle.Translate)), Rgba8.Black);
    canvas.FillPath(Path.Circle(new Vector2(150, 75), 20).Apply(PathEffect.Hatch(Matrix3x2.CreateScale(1, 5) * Matrix3x2.CreateRotation(0.6f), width: 1)), Rgba8.Black);
}

// A line that draws itself: trim it to a growing fraction of its length, frame by frame.
Path frame30 = data.Apply(PathEffect.Trim(0, 0.3f));
