示例1: Main
public static void Main()
{
var w = 800;
var h = 600;
// create a new Canvas
var canvas = new Canvas();
canvas.Width = w;
canvas.Height = h;
// add canvas to the div with id = "target" (defined in MainPage.html)
Element.GetById("target").AppendChild(canvas);
// get the 2D context for the canvas, which contains all the draw methods
var context = canvas.Get2DContext();
// draw background rect
context.FillStyle = new RgbStyle(0xcc, 0x66, 0x99);
context.FillRect(0, 0, w, h);
context.LineWidth = 2;
// draw flowers
context.StrokeStyle = new RgbStyle(0x33, 0x33, 0x33);
context.FillStyle = new RgbStyle(0xff, 0xff, 0);
DrawFlower(context, Math.Min(w, h) * 0.4, 25d, 0.5 * w, 0.5 * h);
context.FillStyle = new RgbStyle(0xff, 0x0, 0);
DrawFlower(context, Math.Min(w, h) * 0.1, 12d, 0.5 * w, 0.5 * h);
