C# Class Smrf.NodeXL.Visualization.Wpf.GraphImageScaler

Sets the graph scale on a NodeXLControl and later restores the original graph scale.
This prepares the NodeXLControl for being saved as an image. It adjusts the control's graph scale so that the graph's vertices and edges will be the same relative size in the image that they are in the control.

Call SetGraphScale before saving the image, then call to restore the original graph scale.
