Resizing the Image
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 Image Tool window.
The Zoom option menu button allows you to display the image as a smaller or larger size. The zoom function works as follows:
1. Click
MB1 on the
Zoom option menu button.
2. Choose the desired zoom factor for the image by clicking MB1 on the value. Zoom factors preceded by a ‘/’ reduce the size of the displayed image; those preceded by an ‘x’ enlarge it.
If Auto Redraw is selected (the default) when you choose the zoom factor, the zoom is immediately applied to the image. 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 image size. If you first choose a Zoom value of / 2 to get a half-size image and then choose x 2, the final image will be twice the size of the original, not the same size as the original. Resizing operations only change the displayed image. Original data is not affected. |
