I have created a WPF UserControl library. And I would like to put a vector picture of each UserControl (in default settings) to documentation. So my question is: How do I create a vector image of a UserControl?
Thanks for any efforts.

Capture a vector image seems difficult, and is you control composed of vector graphics only? If you just wish to get a png or bmp, below code might help:
ImageCapturer.SaveToPng(AnyControl, "Capture.png");
class ImageCapturer
{
public static void SaveToBmp(FrameworkElement visual, string fileName)
{
var encoder = new BmpBitmapEncoder();
SaveUsingEncoder(visual, fileName, encoder);
}
public static void SaveToPng(FrameworkElement visual, string fileName)
{
var encoder = new PngBitmapEncoder();
SaveUsingEncoder(visual, fileName, encoder);
}
private static void SaveUsingEncoder(FrameworkElement visual,
string fileName, BitmapEncoder encoder)
{
RenderTargetBitmap bitmap = new RenderTargetBitmap(
(int)visual.ActualWidth,
(int)visual.ActualHeight, 96, 96, PixelFormats.Pbgra32);
bitmap.Render(visual);
BitmapFrame frame = BitmapFrame.Create(bitmap);
encoder.Frames.Add(frame);
using (var stream = File.Create(fileName))
{
encoder.Save(stream);
}
}
}
