20 * a zoomer and emits the region which should 20 * and you can allow the user easily zooming/moving

22 * All you need to do is to supply a image/pixmap, the visible size
23 * and the original image/pixmap size and the current visible top/left
24 * position.
25 *
26 * This Image works perfectly with QScrollView as you can connect
27 * QScrollView::contentsMoving to setVisiblePoint slot and the zoomAreRel
28 * to the QScrollView::scrollBy slot. Now you would only need to watch
29 * the resize event anf give us the new information about QScrollView::viewport
30 *
31 * You need to position and set the size of this widget! using setFixedSize() is quite
32 * a good idea for this widget
