Horizonatal Scrolling in FlowDocumentScrollViewer

I have a flow document with images (created from drawings). I have provided a button for the user to enlarge the images (zoom) independently without zooming the text开发者_运维技巧.

Is there anyway, I can force the FlowDocumentScrollViewer to display a horizontal scrollbar for scrolling when the images are enlarged? Currently, the enlarged images are simply clipped off.

Best regards,

Paul.

Found the answer, setting the PageWidth of the document does the trick.
