Rescaling the Surface
Often times image variables are so large that normal visualization techniques become time consuming, or so small that they are difficult to analyze visually. One way of effectively dealing with this is to use the Zoom feature located in the controls area of the WzSurface window.
The Zoom slider allows you to display the surface at a smaller or larger size. The zoom function works as follows:
Enter a scale value in the text entry box to the right of the slider. The scale is between 0.1 and 2.0. The default value is 0.6.
If Auto Redraw is selected (the default) when you choose the zoom factor, the zoom is immediately applied to the surface. If Auto Redraw has been disabled, you can use the Redraw button from the button bar to apply the zoom.
note | The Zoom value is always referenced to the original surface size. |
