Diagram zoom out from rectangle api !?

Hello, I am using mindFusion controls for my wpf diagraming needs. Recently i got stuck with zooming out logic..

To zoom into a particular selected diagram area i am using;
diagram.ZoomToRect(diagram.Selection.Bounds, true); //works fine, with a lot of zoomIn % though.

How can I zoom Out (say, 30 units) based on the area selected. Do we have something like: ZoomOutFromRect.. !? Roll Eyes

Thanks a ton.

Hi,

Try this -

Code
Select All
diagram.SetZoomFactor(
    diagram.ZoomFactor - xx,
    Center(diagram.Viewport));


or

Code
Select All
var viewport = diagram.Viewport;
viewport.Inflate(xx, yy);
diagram.ZoomToRect(viewport, true);


Regards,
