Create border around the diagram

Hi,

I am relatively new to diagrammming in Mind Fusion: How do I go about creating a simple border around my entire diagram? This is mainly required for when the diagram is exported to PDF.

Hi,

You could add a temporary node as a border before exporting, and remove it after that:

Code
Select All
diagram.AutoResize = AutoResize.None;

var border = diagram.Factory.CreateShapeNode(diagram.Bounds);
border.Brush = Brushes.Transparent;
border.ZIndex = -1000;

PdfExporter.Export(...);
diagram.Nodes.Remove(border);


There are other ways to draw border on screen, e.g. by handling the DrawBackground event, but only the temp. node method seems to work in my tests when exporting.

I hope that helps,
Stoyan

Great, thanks Stoyan.

The temporary node works nearly perfectly - even after setting the temp nodes obstacle property to false, the LinkLabels I have in the diagram overlap other nodes they are adjacent to. This was a minor issue for me as I could place the labels on segments further away from any node, however this could be a problem in the future.

Is there any way to prevent the labels from overlapping adjacent nodes in this scenario?

Thanks,

Steve

Obstacle is considered only by the routing function, and it seems the large node prevents LinkLabel.AutoArrange from finding correct positions. For the time being you could create four thin nodes at each side of the diagram instead a large one covering all of it.

I hope that helps,
Stoyan
