颜色渐变(Gradient)定义了颜色从一种颜色到另一种颜色的平滑过渡，引路蜂二维图形库支持线性和圆形渐变

private void Gradients()
{
 /* The linear gradient color */
 LinearGradientBrush brush1;
 /* The radial gradient color */
 RadialGradientBrush brush2;
 
 int[] fractions = new[] { 13, 242 };
 Color[] colors = new[] { new Color(0xffff6600, false), new Color(0xffffff66, false) };
 brush1 = new LinearGradientBrush(50, 50, 150, 125, fractions, colors, Brush.NoCycle);
 
 fractions = new int[] { 13, 128, 255 };
 colors = new[]{new Color(0xffff6600,false),new Color(0xffffff66,false),
    new Color(0xffff6600,false)};
 brush2 = new RadialGradientBrush(90, 100, 50, fractions, colors);
 
 //Clear the canvas with white color.
 graphics2D.Clear(Color.White);
 graphics2D.FillRectangle(brush1, new Rectangle(10, 75, 120, 80));
 
 Pen pen = new Pen(brush2, 8);
 graphics2D.DrawOval(pen, 20, 60, 100, 50);
}
