Try removing all of the references to draw2d. Just save an Image of that
size with some random lines on it if necessary. If you still see the
problem, open a bugzilla against SWT.

Thanks Randy,
You are right, I have exported an empty ImageData (the modified snippet is
below) and even empty it doesn't works. Thus, I think it is a problem from
elicpse.SWT. But I don't understand, GEF can export in JPG and no bug was
ever reported.
Have you ever met this kind of problems ?
GC gc = new GC(image);
Graphics graphics = new SWTGraphics(gc);
graphics.dispose();
gc.dispose();
ImageData data = image.getImageData();
ImageLoader loader = new ImageLoader();
loader.data = new ImageData[1];
loader.data[0] = data;
loader.save(filename, SWT.IMAGE_JPEG);
Sabri.
