如何以编程方式更改画布的比例？

Question

给定一个画布对象：

MainCanvas = new Canvas();
MainCanvas.Name = "myCanvas";
MainCanvas.Height = 100;
MainCanvas.Width = 100;

如何通过代码设置其比例（x和y）？

Answer 1

试试这个：

ScaleTransform scale = new ScaleTransform(MainCanvas.LayoutTransform.Value.M11 * ScaleRate, MainCanvas.LayoutTransform.Value.M22 * ScaleRate);
MainCanvas.LayoutTransform = scale;
MainCanvas.UpdateLayout();
