Save Diagram Image Programmatically [message #1269095]

I've been trying to save, PROGRAMMAtically,a graphiti diagram .

I found DefaultSaveImageFeature, which uses ExportDiagramDialog, and after analysing it, I notice there is not a easy way to do that,i.e., I don't use exportdiagramdialog, but it is used to get the figure and configure other parameters. The parameters may passed to exporter in a easy way, but to get the figure it is used the dialog, so I needed to extract the code to get the figure from that.

Is there an easy way or better way. Am I over thinking, or this must be done in this way?

Thanks.

Rui,

if you don't have an editor that surely is not easy.

When you have an open editor showing the diagram you could simply reuse the
GEF figures from that. The DiagramBehavior instance holds a map of pictogram
elements to edit parts and figures and you can simply call
getFigureForPictogramElement() to get the figure for a pictogram element.

Does that help?

Michael

HI Michael. Thanks for your answer.
I understant it wouldn't be easy, if I've no editor. But is it possible?
Can you elaborate a bit on how to get in the right Path? If you know how.

I believe I have to generate edit parts like in OffScreenFactory of GMF, but for now I didnt think about how to start.

Thanks in advance
rui
