Chapter 11 Raster Manipulation

The del_spurs command is used to remove all spurs which are less than or equal
to the specified number of pixels.  A spur is defined as a segment with at
least one end free.  The changes can be saved with a save command.  No
modifications to the vector file will occur.  NOTE: To recover deleted spurs,
use the recall command.

del_spurs n

    deletes spurs from the raster.
     
         del_spurs n

    Removes all spurs <= n pixels in length from the raster display.  A spur is
    defined as a segment with one free end (not connected to any other
    segment).  To save these changes, execute the save command.  Assembly is
    not required.
