Diamond gradient

[jimmygyuma]

I would sure like to know how you do the diamond gradient. The best I've been able to do is:

public void fillStarDiagGrad(Bitmap src, Color c1, Color c2)

{

int w = src.Width;

int h = src.Height;

Rectangle rect = new Rectangle(0, 0, w, h);

GraphicsPath path = new GraphicsPath();

path.AddRectangle(rect);

PathGradientBrush brush = new PathGradientBrush(path);

brush.CenterColor = c1;

Color[] surroundColors = new Color[] { c2 };

brush.SurroundColors = surroundColors;

Graphics g = Graphics.FromImage(src);

g.FillPath(brush, path);

}

which creates a diamond with the points pointing toward the corners of the rectangle, which is fine, but I also want a diamond with the points pointing vertically and diagonally, regardless of the rectangle. (A 90 degree diamond which I could point in any direction would be even nicer.)

Could anyone point me in the right direction?

Paint.NET does not use GDI+ (aka System.Drawing.*) for its gradients. It renders all the pixels using custom code in the GradientRenderers class.
