Namespace

What a cell of a Lattice draws.

public enum LatticeCellKind

Fields

Default = 0

The cell's part of the image.

FixedColor = 2

The cell's color in CellColors, filling the cell.

Transparent = 1

Nothing: the cell is left as it is.

Examples

using (RasterCanvas<Rgba8> canvas = raster.CreateCanvas())
{
    // An Android .9.png: its one-pixel border marks what stretches. The corners stay sharp at any size.
    (Raster inner, Lattice lattice, Rect? padding) = NinePatch.FromAndroid(file);
    canvas.DrawImageLattice(inner, lattice, new RectF(10, 10, 180, 48));
    inner.Dispose();

    // A nine-patch from a plain image: the 8-pixel corners keep their size, the edges and center stretch.
    canvas.DrawImageNinePatch(frame, new Rect(8, 8, 8, 8), new RectF(10, 70, 120, 40));

    // A lattice can leave cells out or fill them with a color: here the center becomes a flat panel.
    LatticeCellKind[] kinds = [.. Enumerable.Repeat(LatticeCellKind.Default, 9)];
    kinds[4] = LatticeCellKind.FixedColor;
    RgbaF32[] colors = new RgbaF32[9];
    colors[4] = new RgbaF32(0.95f, 0.95f, 0.9f, 1);
    canvas.DrawImageLattice(frame, new Lattice([8, 16], [8, 16]) { CellKinds = kinds, CellColors = colors }, new RectF(150, 70, 140, 40));
