Scan Area & Cropping
For those instances not requiring the full scan area of the camera, fully variable 
image cropping is provided. Both proportional cropping (using the Scan Area up/
down buttons) and manual cropping (using the crop tool or the Size panel) can be 
used to select any desired rectangular area within the full scan area. In addition to 
reducing the size of a scanned image file by eliminating unwanted data, cropping 
can decrease overall scan times by reducing the number of lines to be scanned. 
To use proportional cropping
, click the Scan Area Increase 
 or Decrease 
 buttons; click and 
hold either button to advance rapidly through the selections. Each click causes the cropping rectangle 
to grow or shrink proportionally, until an image boundary is reached. 
  Hold down the Option key and click on the 
Scan Area Increase button to move immediately 
to the largest scan area (100%) or the 
Scan Area Decrease button to move to the smallest 
scan area (1%).
To use manual cropping
, select the Crop Tool   from the tools located above the preview 
window. The crop rectangle will appear in the preview window with a handle in the center of each 
edge and a handle in each corner. When the mouse cursor is moved over one of the handles the cursor 
will change to a  ,   or   to indicate the direction the edge or corner can be moved. Click and drag 
one of the handles to resize the crop rectangle. The crop rectangle will change as long as the mouse 
button is held down. When the rectangle edge or 
corner is at the desired location, release the mouse 
button. When the cursor is within the crop rectangle 
the cursor will change to a   to indicate that the 
crop rectangle may be repositioned by clicking and 
dragging the cursor to move the crop rectangle to 
the desired location. Changes to the crop rectangle 
will affect the Scan AreaScan TimeImage Size 
and histogram displays and these will update in real 
time as the crop rectangle is adjusted.
