To employ this feature it is necessary to have two or more ImageWorks sessions running on the same machine, started by the same user as determined by the userid. Then the user selects the "Link" radio button on the Link Control panel of each of the ImageWorks sessions to enable the link.
After this is done, moving the cursor in one of the linked ImageWorks sessions should cause the cursor to track in all other linked ImageWorks sessions. The locations will track according to the georeferenced location of the cursor if the georeferencing types match, otherwise they will track according to the ImageWorks pixel/line coordinates.
The link option can be tried out on the demonstration files irvine.pix, eltoro.pix, and map100.pix. First launch three copies of ImageWorks, from the command line or from VDINIT. Then load them with the demonstration file irvine.pix using the "File|Load Imagery" panel. Then select View|Link (select the "Link" toggle from the "View" menu) in each of the ImageWorks sessions. Thereafter, moving the cursor in any one of the ImageWorks sessions should result in the cursor tracking to the same georeferenced location in the other two ImageWorks windows.
Linked cursors can be disabled by selecting the ``Unink'' radio button on the Link Control panel.
