How to: Encode a Visual to an Image File
This example demonstrates how to encode a xref:System.Windows.Media.Visual object into an image file using a xref:System.Windows.Media.Imaging.RenderTargetBitmap and a xref:System.Windows.Media.Imaging.PngBitmapEncoder.
Example
The xref:System.Windows.Media.DrawingVisual is created using a xref:System.Windows.Media.Imaging.BitmapImage and xref:System.Windows.Media.FormattedText which is rendered to a xref:System.Windows.Media.Imaging.RenderTargetBitmap. The rendered bitmap is then used to create a xref:System.Windows.Media.Imaging.BitmapFrame which is added to the xref:System.Windows.Media.Imaging.PngBitmapEncoder to create a new Portable Network Graphics (PNG) file.

A xref:System.Windows.Media.Imaging.PngBitmapEncoder was used in this example but any of the derived xref:System.Windows.Media.Imaging.BitmapEncoder objects could have been used to create the image file.
