Select > Clipboard > Copy

Use the Copy command (<Ctrl> +<C>) to copy the contents of the selected ROI to the Window Clipboard.  If no ROI is active, Image-Pro copies the entire active image to the Clipboard.  Copy will not change the contents of the image in the active window (i.e., copy does not delete the copied pixels).  Any data already existing on the Clipboard will be replaced.

The copied data can be pasted into the active window or into another open window using the Paste command.  You can also create a new window directly from the Clipboard contents using the Paste New command.
