如何在WPF和c＃中更改SVG图像的前景色

Question

我们正在尝试从SVG获取位图，但它没有给出精确的坐标来改变像素颜色。任何人都可以帮助我如何更改wpf中位图像素/ svg像素的颜色。

WpfDrawingSettings wpfDrawingSettings = new WpfDrawingSettings { IncludeRuntime = false, TextAsGeometry = false, OptimizePath = true };
        StreamSvgConverter converter = new StreamSvgConverter(wpfDrawingSettings);
        MemoryStream ms = new MemoryStream();
        converter.Convert(str, ms);


        BitmapImage bitmap = new BitmapImage();
        bitmap.BeginInit();
        bitmap.StreamSource = ms;
        bitmap.CacheOption = BitmapCacheOption.OnLoad;
        bitmap.EndInit();
