Convert WPF visuals to Windows metafile (WMF)

There’s already a solution for this, you can convert both visual or UIElemnt to metafile… the only (and the biggest) drawback is that the metafile that you get is not a vector because you are pasting a bmp inside it… here are the links:

and the visuals addon taken from the microsoft forums:

private static BitmapSource CaptureScreen(Visual target, double dpiX, double dpiY)
if (target == null)
return null;
} Rect bounds = VisualTreeHelper.GetDescendantBounds(target); RenderTargetBitmap rtb = new RenderTargetBitmap((int)(bounds.Width * dpiX / 96.0),
(int)(bounds.Height * dpiY / 96.0),
PixelFormats.Pbgra32); DrawingVisual dv = new DrawingVisual();
using (DrawingContext ctx = dv.RenderOpen())
VisualBrush vb = new VisualBrush(target);
ctx.DrawRectangle(vb, null, new Rect(new Point(), bounds.Size));
} rtb.Render(dv); return rtb;

EDIT: if your visual/UIElement has transparent background, the code supplied above will make an image with black background… the workaround is to use the PngBitmapEncoder instead of BmpBitmapEncoder
