button on the main tool bar.Magnifier Mode
You turn on the magnifier mode by clicking the button on the main tool bar.
Activating the magnifier mode pops up a magnifier window, docked just below the main tool bar. When the magnifier window is in this docked position, you can change its settings. You can also resize the magnifier window to enlarge or reduce the area that will be magnified.
When you click and drag the cursor over the image area, the cursor changes to a crosshair and the magnifier windows is follows the cursor. As you move the cursor, the magnifier is continuously updated with image data centered on the cursor location. When you release the mouse button, the magnifier window returns to its docked location.

Magnification
This control lets you set the magnification factor. A factor of 1X displays the magnified image at a zoom factor of 1:1. Higher factors replicate pixels to make the image larger, Lower factors shrink the image by averaging groups of pixels.
