如何在DrawingImage/DrawingContext中绘制无模糊/模糊线？

// 创建一个DrawingVisual对象
DrawingVisual drawingVisual = new DrawingVisual();

// 获取DrawingContext对象
using (DrawingContext drawingContext = drawingVisual.RenderOpen())
{
    // 创建Pen对象并设置线条属性
    Pen pen = new Pen(Brushes.Black, 2);
    
    // 绘制无模糊线
    pen.DashStyle = DashStyles.Solid;
    drawingContext.DrawLine(pen, new Point(0, 0), new Point(100, 100));
    
    // 绘制模糊线
    pen.DashStyle = DashStyles.Dash;
    drawingContext.DrawLine(pen, new Point(0, 100), new Point(100, 0));
}

// 创建DrawingImage对象并添加DrawingVisual
DrawingImage drawingImage = new DrawingImage(drawingVisual.Drawing);

// 将DrawingImage对象渲染到画布或其他可视化元素上
// canvas是一个可视化元素，可以是任何支持绘制的容器
canvas.Background = new ImageBrush(drawingImage);
