Exporting as Image [message #238373]

Hi,
I have an editor that has a FreeFormLayer with custom editparts and
connections.
I want to export this as an image ( JPEG ).

I used the code snippet found here:
http://dev.eclipse.org/newslists/news.eclipse.tools.gef/msg0 5012.html

I don't see the connections in the exported image.

What do I need in order to do that?

Thanks

You must have saved the figure before being displayed over editor.
Save it once your editor/shell is opened.

Here is a piece of code that works for me. At the end you have ImageData in
your display color depth that can be saved or processed further.

GraphicalViewer viewer = (GraphicalViewer)
getWorkbenchPart().getAdapter( GraphicalViewer.class );
LayerManager layers = (LayerManager) viewer.getEditPartRegistry().get(
LayerManager.ID );
IFigure figure = layers.getLayer( LayerConstants.PRINTABLE_LAYERS );
Rectangle bounds = figure.getBounds();
if( figure instanceof FreeformFigure) {
bounds = ((FreeformFigure) figure).getFreeformExtent();
}
Image image = new Image( Display.getDefault(), bounds.width,
bounds.height );
boolean antialiasing = false;
GC gc = new GC( image );
gc.setAntialias( antialiasing ? SWT.ON : SWT.OFF );
gc.setTextAntialias( antialiasing ? SWT.ON : SWT.OFF );
Graphics graphics = new SWTGraphics( gc );
graphics.translate( bounds.getLocation().negate() );
figure.paint( graphics );
graphics.dispose();
gc.dispose();
ImageData imageData = image.getImageData();
image.dispose();
