如何从文件加载图像并将其绘制在 WPF Skiasharp canvas 上？

Question

SkiaSharp WPF <- 重要

我想在我的 SkiaSharp canvas 上的特定位置显示 Compass.png 图像。我已经在 canvas 上画线和圆圈了，我不需要帮助。

private void MyCanvas_PaintSurface(object sender, SKPaintSurfaceEventArgs e)
{
  var surface = e.Surface;
  var canvas = surface.Canvas;
    
  canvas.Clear(SKColors.Black);
    
  // ... working drawing code drawing lines/circles already here
    
  // ** Need to add code here to load the compass image from the file and display it on the canvas at say (0, 0)?
}

注：WPF。

Answer 1

解决了...

var image = SKImage.FromEncodedData(@"Images\Compass.png");
var bm = SKBitmap.FromImage(image);

canvas.DrawBitmap(bm, new SKPoint(0, 0));

显然，最好只设置一次 bm 并重新使用它。
