Hi,
I was wondering how I could get from an object of class
org.eclipse.swt.graphics.Image to a file. I have seen that ImageLoader can
load and save image but how do I get and InputStream so that I can do as
follows:
Image myImage;
...
InputStream myImageInAnInputStream;
...
ImageLoader loader= new ImageLoader();
loader.load(myImageInAnInputStream);
loader.save("c:\temp\MyImage.bmp",SWT.IMAGE_BMP);
thank you very much
Guillaume

After research, this is what I found (and it works):
Image img = new Image(null, root.getFigure().getPreferredSize().width,
root.getFigure().getPreferredSize().height);
GC gc = new GC(img);
Graphics graphics = new SWTGraphics(gc);
root.getFigure().paint(graphics);
graphics.dispose();
gc.dispose();
ImageData data=img.getImageData();
ImageLoader loader=new ImageLoader();
loader.data= new ImageData[]{data};
loader.save("c:\\test.bmp",SWT.IMAGE_BMP);
Where root is the RootFigure of my editor (RootEditPart.getFigure())
