Why do you need the layout? You can just put a drawingarea inside a scrolledwindow. To zoom, just change the size of the drawing area and queue a repaint. > To achieve zooming I handle the scroll event by scaling the original > size pixbuf and copying it to an off screen pixbuf that is copied on > the drawingarea in the expose_event handler. This will waste a lot of memory in the X server. I would keep the original image in your client program, then in the expose handler, just zoom up the bit of the image you need.
