Settings window
This lets you lock in 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.
Important: 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.
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.
Additional Notes
When none of the Scan Frame options (locks) are locked, all five edit
boxes are enabled, allowing you to edit or enter values into any of
the boxes.
The scan frame and output size locking options are exclusive each
other. This means that only one of the locks can be locked at a
time; locking one of the options will automatically unlock the
other.
Transform
The Transform command allows you to rotate and / or flip the image in
increments of 90 degrees.
The effects of the Transform command will be seen in the Prescan image
or are after you click the Scan To button and scan the image in; the
Transform effect is not shown in the Overview viewing mode.
