Turning Off Auto Redraw
The WzImage controls area has a pre-selected control button for automatic redrawing of the image whenever a change is made to the brightness or contrast control scales. You may want to turn off the auto redraw function to save processing time, if your image is very large and takes considerable time to be redrawn. To do this:
*Position the pointer on the Auto Redraw button and click MB1.
 
note
If the Auto Redraw button is deselected, you must manually select the Redraw button on the button bar whenever you want to see your brightness or contrast changes applied.
