Contouring Zoom Dialog
Contour Zoom Dialog
When displaying contours over a background image, you can zoom the background image and the overlay contours individually, so that the locations in the contours match the locations in the background image.
Picture Zoom -- Use this sliding control to adjust the zoom of the background image.
Overlay Zoom -- Use this sliding control to adjust the zoom of the contours overlaying the background image.
Redraw Dynamically -- If this box is checked, the image will be redrawn during zooming. Because drawing the background image and contours is very slow, a fast processor is required for effective dynamic redrawing.
