Hi everybody!
I've got a question for you pals.
I have a gef editor. Everything is fine apart from one thing.
Some figures are drawn in editor using pictures like these:
protected void outlineShape(Graphics graphics)
{
Rectangle bounds = getBounds().getCopy();
if (m_image != null)
graphics.drawImage(m_image, bounds.x, bounds.y);
}
When zoom come into play I am zooming those pictures on my own, i.e.
increasing resolution of my pictures, but GEF tries to do the same, which I
don' want to happen because these results into double zooming so to speak.
How do I avoid that?
Thanks a lot in advance for your help.

How to avoid the double zooming? Not zoom it on your own.
BTW, you don't need to copy the bounds in your outlineShape() method, since
you're not modifying them.

Hi, Pratik
Thanks again for your answer.

I thought maybe a good solution is not to changed the size of the picture
but just change its resolution? What do you think?

It's not exactly clear to me what you're trying to do. If you think the
image is too grainy when zooming, you can definitely switch to an image with
a different resolution. To do that, just listen for changes to zoom and
switch out the image being used. The next paint invocation will then draw
the new image. However, as zooming occurs, the amount of space this image
takes up on the screen definitely needs to grow and shrink. And that is
handled internally by ScaledGraphics. So, you should always just keep
drawing the image to fill up the bounds of its figure.
