Adjusting Cropping Frames (IJ Scan Utility)
"Cropping" is the act of selecting the area you want to keep in an image and discarding the rest when
scanning it.
In the Image Stitch window, you can specify a cropping frame on the image displayed in the Preview area.
Note
See "Adjusting Cropping Frames (ScanGear)" for your model from Home of the Online Manual for
how to adjust cropping frames with ScanGear (scanner driver).
Initial Cropping Frame
No cropping frame is specified. When you select the Adjust cropping frames checkbox, an active

frame to specify the area.
When you perform a scan, the image in the area specified with the cropping frame will be scanned.

The cursor will change into (Crosshair Arrow) when it is positioned within a cropping frame. Click and
