You can use the measuring tool to measure distances
between pixels. When you position it and click the mouse
and drag to another place, the measured distance in pixels
will appear within a rectangular box. The measuring tool is
automatically constrained to 45 degree angles, horizontal or
vertical straight lines. Hold down the Shift key to move it
freely.
When the lock icon is in the locked position, you can access
the measuring tool by typing “7.”
The magnifying tool can increase the screen size of the
bitmap by 2, 4, 8, or 16 times its actual size. When the tool
appears on-screen, click the mouse and release to show a
magnified version. Clicking again increases the
magnification unless there isn’t a larger size, in which case
an empty magnifying tool will appear.
To reduce the size of the bitmap, hold down the Option or
Alt key. The magnifying tool will display a minus sign.
When the lock icon is in the locked position, you can access
the magnifying tool by typing “8.”
When you can no longer enlarge the image, the
magnification tool will display nothing in its center.
