Hi,
I have a GEF Editor where if I save the figure to an image some of the
connections are cut short in the saved image if the diagram is bigger
than the viewport and scroll bars are needed.
I save as follows:
GraphicalViewer diagramViewer;
File file;
....
ScalableFreeformRootEditPart rootEditPart =
(ScalableFreeformRootEditPart)diagramViewer.getRootEditPart( );
IFigure figure = rootEditPart.getLayer(LayerConstants.PRINTABLE_LAYERS);
Rectangle rectangle = figure.getBounds();
Image image = new Image(Display.getDefault(), rectangle.width + 50,
rectangle.height + 50);
GC gc = new GC(image);
SWTGraphics graphics = new SWTGraphics(gc);
figure.paint(graphics);
ImageLoader loader = new ImageLoader();
loader.data = new ImageData[]{image.getImageData()};
loader.save(file, SWT.IMAGE_PNG);
....
Anyone come across this?
PB
