Re: [platform-swt-dev] Draw

To draw on an image, you can do the following:

      Display display = new Display();
      Image image = new Image(display, 100, 100);
      GC gc = new GC(image);
      gc.drawLine(0, 0, 100, 100);
      gc.dispose();
      image.dispose();

You might be out of luck when it comes to writing the image to file. There
is API to do this:

      FileFormat.unloadIntoStream(ImageData data, LEDataOutputStream
stream);

but the file format classes are internal. Probably shouldn't be used.

You could get the data from the Image - Image.getImageData() - and write
that to a file yourself.

Hi There,

I need some documentation or a simple example of how I would go about
drawing a line on a image in swt and then saving that image to a file.

What should I draw on - canvas?

Regards,
Maxine.
