66 Microtek ScanWizard Pro for Mac OS X
Locks
The Locks control the behavior of the Scan Frame settings and the Output
settings. A third Lock lets you keep the proportion for image width and height.
A. Scan Frame lock
This lets you lock in the settings of your scan frame,
so that the width and height dimensions of the frame
are always preserved no matter where you move the
frame in your preview image.
If you know the exact input size for your image, or if
you wish to “lock” the settings of your scan frame to
a particular size, enter the Scan Frame width and
height values first, then click the Scan Frame lock.
Your scan frame will be “fixed” at those values, so
even if you move the scan frame around the preview image, the dimensions of
the frame itself will remain unchanged.
B. Output lock
This lets you lockin the values specified for the width and height of the image
when it is output. For example, if you know the exact output size for your
image, enter the output width and height values first, then click the Output lock.
The image will then be scanned and output at the values you specify.
Note: If any of the input values are changed after the lock is on, the scaling will
be adjusted automatically to preserve the output dimensions correctly.
C. Keep Proportion lock
This lets you keep the proportion of the image width and height despite
changes made to either setting, and thus preserves the aspect ratio of the image
correctly. The Keep Proportion lock is automatically turned on when you enter
values in either the Scan Frame settings or the Output settings.

Frame lock
Note: The Scan
Frame Lock and
Output Lock are
each mutually
exclusive. This
means that only
one lock can be
used at a time.
