Question

I have a VisualBrush and need this VisualBrush as a Drawing. Anyone knows how this can be done? Thanks for any hint!

Answer 1

Your question doesn’t really make sense, because a VisualBrush is unrelated to a Drawing (it would make more sense with a DrawingBrush). However, you can create a Drawing by using the VisualBrush to paint on it. Something like that should work :

public static Drawing GetDrawing(TileBrush brush)
{
    DrawingVisual drawingVisual = new DrawingVisual();
    DrawingContext drawingContext = drawingVisual.RenderOpen();
    drawingContext.DrawRectangle(brush, new Pen(Brushes.Transparent, 0.0), brush.ViewPort);
    drawingContext.Close();
    return drawingVisual.Drawing;
}

(this is valid for any brush inherited from TileBrush, not just a VisualBrush)
