使用SkiaSharp进行绘制

vs版本:2019

skiasharp版本: 2.88.0

1. 安装SkiaSharp以及SkiaSharp.Views.WPF

在VS中启动程序包管理控制台, 输入如下命令

1. 1 获取SkiaSharp包

PM> Install-Package SkiaSharp -Version 2.88.0-preview.150

1.2 获取WPF支持

PM> Install-Package SkiaSharp.Views.WPF -Version 2.88.0-preview.150

 

2. 新建WPF程序

1. 在xaml设置设置布局

Grid为两行

在windows标签中, 引入SkiaSharp.Views.WPF命名空间

xmlns:skia="clr-namespace:SkiaSharp.Views.WPF;assembly=SkiaSharp.Views.WPF"

 

在Grid标签中插入画布

<skia:SKElement Name="MyView" Grid.Row="0" PaintSurface="onCanvasViewPaintSurface">          
        </skia:SKElement>

3. 实现PaintSurface事件处理程序

        private void onCanvasViewPaintSurface(object sender, SKPaintSurfaceEventArgs e)
        {
            SKImageInfo info = e.Info;
            SKSurface surface = e.Surface;
            SKCanvas canvas = surface.Canvas;

            canvas.Clear();

            SKPaint paint = new SKPaint
            {
                Style = SKPaintStyle.Stroke,
                Color = Colors.Red.ToSKColor(),
                StrokeWidth = 25
            };

            canvas.DrawCircle(info.Width / 2, info.Height / 2, 100, paint);

            paint.Style = SKPaintStyle.Fill;
            paint.Color = SKColors.Blue;
            canvas.DrawCircle(info.Width / 2, info.Height / 2, 100, paint);
        }

4. 编译生成,效果如下
