The Cut and Copy functions work identically with the exception that Cutting a block of imagery will blank out (set to zero) the selected rectangle, while Copying does not affect the selected area. After selecting Cut or Copy mode on the Image Editing Panel a rectangle is dragged out with the left mouse button depressed and the cut/copy takes place when the mouse button is released. The Escape key may be used to cancel an action during a drag.
The Paste function overwrites a region of imagery with the contents of the image clipboard. The saved imagery is not destroyed and may be pasted multiple times. After Paste on the Image Editing Panel has been selected, the paste box may be dragged around in the image window while the left mouse button is depressed. When the mouse button is released the saved imagery data is added to the target region.
Note that the contents of the imagery clipboard are persistent when the viewed image plane(s) are changed, so a region can be Cut or Copied from one image plane and Pasted into another. The Cut and Copy functions will grab one or three image planes worth of unenhanced image data when the Cut or Copy takes place. The enhancement and/or PCT of the image window are not associated with the data in the clipboard.
The Clear mode buttons have no effect on the Cut, Copy, and Paste functions.
