Hi'

I'm experiencing some problems when exporting a PNG since all the Diagramitems placed with negative values in their location are cropped.

The following code causes this behaviour:

var encoder = new PngBitmapEncoder();            encoder.Frames.Add(BitmapFrame.Create(CurrentPage.CreateImage(200)));


Can you provide me with:

1) since I need to call ResizeToFit on the diagram (I've a tree which became very large), I need a method to "reset" or offset the origin of a DiagramPage so that all the items will be moved in the positive axes. E.g. after calling ResizeToFit, the diagram bounds are updated to -1000,-1000, 1000, 1000. But I need that all the items are placed into a diagram located at 0,0,2000,2000.

2) I need a way to move all the items to another location (including links) programmatically so that link's shapes are preserved (as if dragged by mouse when all of them are selected).

Can you point me in the right direction?

A.

Unfortunately I'm experiencing some issues with you code.

I'm using a TabbedDiagramView and If I use the CurrentPage as the Element to be rasterized, the behaviour is very weird
and depends on the zoom and pan (but not consistently).
I cannot find the right combination to produce a bitmap not cropped with the right size.

One note: The TabbedDiagramView has been retemplated to include a Ruler (you posted me the code some weeks ago) if it matters.

Setting var element = diagram.DocumentPlane; in the code above will help avoiding the scroll offset, but not the ZoomFactor scale transform. You will have to temporarily change the zoom level to 100 when exporting, or generate the image from a copy of the diagram (e.g. created by calling LoadFromString(currentPage.SaveToString())) to avoid changes on screen.

I hope that helps,
Stoyan
