The crop rectangle may be locked to maintain the aspect ratio proportional to the size indicated by the Scan Area displays by clicking on the Lock Crop Ratio button in the size tab panel. The button will change to a icon and the aspect ratio of the crop rectangle will be locked out to any manual changes.
The crop rectangle may be moved while it is locked by click- ing and dragging within the center of the cropped area.

The two edit fields on the Size panel marked with and represent, respec- tively, the horizontal and vertical dimensions of the cropped area in the selected units. The popup menu to the right of the dimension fields selects from several types of measurement units (Figure A).
Since the desired print size also relies on the resolution (e.g. pixels per inch) you can set the reso- lution you need, and the software will calculate the size of the file
in megabytes. The number of pixels per dimension unit (e.g. reso- lution of 300 pixels/inch) is typed into the edit field below the dimension fields and the pixels per unit is selected from a popup menu, as shown in Figure B.

The Insert Direction popup menu below the pixels per unit popup is used to select the orientation of the insert in the camera (Figure C). Changing this selection will also change the preview image ori- entation to properly orient the image on the screen.
The crop rectangle will not change orientation.
