Image Zoom Levels
At times you will probably want to see some areas of your image close up. At other times
you may want to see the entire image. To do this, change the zoom level. For example, zoom
in to see the individual pixels for detail work and back out to adjust the color balance.
The zoom level is the magnification level of an image. The normal viewing level is the
actual size of one-to-one (1:1). At three-to-one (3:1), the image is three times the
normal size; at one-to-five (1:5), it is one-fifth the normal size.
Using the View Menu Zoom Commands
The following commands on the View menu change the magnification an image:
· Zoom In by 1:1.5 increases the zoom factor by 1.5.
· Zoom In by 1:5 increases the zoom factor by 5.
· Zoom Out by 1.5 :1 decreases the zoom factor by 1.5.
· Zoom Out by 5:1 decreases the zoom factor by 5.
· Normal Viewing immediately returns the image to the standard
magnification of 1:1.
For example, if you choose View > Zoom in by 1.5 two times, the image will be
displayed at three times its original size.
Using the Zoom Tool
To activate the Zoom tool, click the Zoom tool button on the Tool palette. Use the left
and right mouse buttons to increase and decrease the magnification level.
· To zoom in, left-click the image. The magnification increases by one
level each time you click the image, and the image centers where the Zoom tool was
clicked.
· To zoom out, right-click the image. The magnification decreases by
one level with each click.
To return to the standard view, click the Normal Viewing button on the toolbar or press
<Ctrl> + <Alt> + <N>.
