How To Use The Aspect Lock - Microtek ScanMaker IIG User Manual

How to use the Aspect Lock

The Aspect Lock preserves the ratio of the image width and
height from input to output. For instance, if your image is 2
inches wide by 4 inches high, changing it to 1 inch by 2
inches will maintain its aspect ratio. Changing it to, say, 1 inch
by 4 inches, however, will alter its aspect ratio, so that the
image will be narrower than the original. The notes below
provide more details on how to use the Aspect Lock.
The Aspect Lock is a toggle. Click on it to lock or unlock.

If the Aspect Lock is on: Changing one output edit box (width or
height) will automatically change the other output field, as well
as scaling, to preserve the aspect ratio. With Aspect Lock on,
you cannot edit the input dimensions.
Changing one output field will change the other.
Note that aspect ratio is preserved (input 2x4;
output 4x8); scaling also changed automatically.
If you change any of the output fields, you must highlight
either the other output field or the scaling edit box for the
system to change the other output field. The system will then
make the calculations automatically to preserve the aspect
ratio.
If the Aspect Lock is off: Changing one input edit box (width or
height) will NOT automatically change scaling or the other input
field, and aspect ratio can be changed. With Aspect Lock off,
you cannot edit the output dimensions.
Changing one input field will not automatically
change the other. Note aspect ratio is not
preserved (input changed from 2x4 in previous
box to 3x4).
If you change any of the input fields, press the Enter key so
that the output fields respond to the changes (even though
they remain grayed out). For example, if you change input
width from 2.00 to 3.00, the output width will remain at 2.00
unless you press Enter for the change to take effect.
