Hi all,
I'm facing the problem, that exporting editor content to an image is cut off
at the left coordinate (0,0). Objects dragged beyond that coordinate to the
negative area do not increase the ClientArea.
What am I doing wrong here?
public void doSaveAsJPG(String dir, String filename) {
IFigure figure =
((ScalableFreeformRootEditPart)getGraphicalViewer().getRootE ditPart()).getLayer(LayerConstants.PRINTABLE_LAYERS);
RectangleFigure backgroundFigure = new RectangleFigure();
backgroundFigure.setBounds(new Rectangle(-1, -1,
figure.getClientArea().width, figure.getClientArea().height));
backgroundFigure.setBackgroundColor(ColorConstants.white);
ImageData data = new ImageData(figure.getClientArea().width,
figure.getClientArea().height, 24, new PaletteData(0xFF, 0xFF00, 0xFF000));
Image image = new Image(Display.getCurrent(), data);
GC gc = new GC(image);
Graphics g = new SWTGraphics(gc);
backgroundFigure.paint(g);
figure.paint(g);
ImageLoader loader = new ImageLoader();
loader.data = new ImageData[] { image.getImageData() };
loader.save(dir + File.separatorChar + filename, SWT.IMAGE_JPEG);
image.dispose();
gc.dispose();
g.dispose();
}
Thanks a lot!
Fabian

The figure's trying to paint to the negative coordinates of the image, but
since there are none, it gets clipped. You need to translate the graphics
so that the figure's origin () matches the image's origin (0,0). Try
something like:
g.translate(-figure.getBounds().x, -figure.getBounds().y)

Can you please explain how you solved this?

I solved it by looking at the Thumbnail code  Thanks though!
