		double oldZoomFactor = rendererView.getModel().getZoomFactor();
		if (e.getWheelRotation() < 0) {
			rendererView.getModel().zoomIn();
		} else {
			rendererView.getModel().zoomOut();
		}
		rendererView.getModel().fireProcessZoomChanged();

		// calculate how the scrollbar needs to be adjusted for centered zoom
		double relativeZoomFactor = rendererView.getModel().getZoomFactor() / oldZoomFactor;
		double differenceHorizontal = e.getPoint().getX() * (relativeZoomFactor - 1);
		double differenceVertical = e.getPoint().getY() * (relativeZoomFactor - 1);

		int newX = Math.max(0, (int) (scrollPane.getHorizontalScrollBar().getValue() + differenceHorizontal));
		int newY = Math.max(0, (int) (scrollPane.getVerticalScrollBar().getValue() + differenceVertical));

		scrollPane.getHorizontalScrollBar().setValue(newX);
		scrollPane.getVerticalScrollBar().setValue(newY);

		// prevent flickering when another adjustment of the scrollbars is needed
		RepaintManager.currentManager(scrollPane).markCompletelyClean(scrollPane);

		/**

		 * updated to the size changes caused by the zooming. Set flag an values to try

		desiredHorizontalScrollValue = newX;
		return;

	Container p = rendererView.getParent();
	if (p != null) {
		p.dispatchEvent(SwingUtilities.convertMouseEvent(rendererView, e, p));
