 Crop Mask Tool
When working with cropped areas for scanning, a crop mask may be displayed on the preview 
by selecting the Crop Mask tool 
 from the top set of buttons or by pressing and holding the Com-
mand key 
 (Control key in Windows) and pressing and releasing the slash key (/) (aka virgule 
key). A crop mask will appear surrounding the cropped area in the preview image.
The color and transparency of the crop mask are determined by settings in the Preferences 
window. The color used for the mask may be selected by clicking on the Color button in the Mask 
section and selecting a color from the Color Picker. The transparency of the mask is selected by 
moving the slider to the right for more opacity and the left for more transparency (Windows) or by 
moving the transparency slider in the Color Picker (Macintosh).
 These same settings can be accessed 
by double-clicking on the area covered by the crop mask in the preview image (Macintosh) or by 
double right-clicking in the preview image (Windows). The appropriate Preferences window will 
appear to set the mask preferences.
 Grid Tool
An alignment grid may be displayed on the preview by selecting the Grid tool 
 from the top 
set of buttons or by pressing and holding the Command key 
 (Control key in Windows) and 
pressing and releasing the apostrophe key (‘). The color and default spacing of the grid are determined 
by settings in the Preferences window. 
The positioning of the grid may be changed by moving the mouse into the preview image and 
pressing and holding the Control key
 and moving the mouse. The cursor will change to a grid align-
ment icon and the grid may be positioned as long as the Control key remains depressed.
The spacing of the grid may be manually adjusted by pressing and holding the Control and 
Shift keys
 and moving the mouse in the preview image. As the mouse is moved upward, the hori-
zontal grid lines will be placed closer together. Correspondingly, as the mouse is moved leftward, the 
vertical line spacing will be reduced. The grid lines have a minimum spacing of two pixels apart and a 
maximum spacing of 500 pixels.
The grid spacing may be set precisely in the Preferences window in the Grid section. Exact pixel 
spacings may be entered manually into the edit fields or the up and down arrows may be used to 
increment or decrement the values until the desired spacing is achieved. 
The color used for the grid may be selected by clicking on the Color button in the Grid section of 
the Preferences and selecting a color from the Color Picker.
