Chapter 11 Raster Manipulation

A raster may be turned, or rotated, about its center, in increments of 90
degrees (1/4 turn) by executing the rotate command.  If no degree value is
entered, the rotation is assumed to be 90 degrees.  Counterclockwise rotation
may be accomplished by entering a negative (-) value.  Rotating a raw
(unassembled) raster will require less time than rotating assembled data.

IMPORTANT NOTE:  Invoking the reflect command against an assembled (vectorized)
or attributed map is very dangerous!  The vectorization and all attributes will
be permanently LOST.  The map will need to be re-assembled and re-attributed.
Map registration will also be LOST.  The map will require total re-registration
(both raster and geodetic).

Note also that if a b-raster (original scan) exists, it will be replaced 
automatically by a copy of the (new sized) editable raster.  This is necessary 
because the raster sizes need to be identical.

rotate

    Rotates the active raster.
     
         rotate d

    Rotates the raster 90 degrees (default) or in increments of 90 degrees,
    clockwise.  Note that a raw raster will rotate in less time than an
    assembled raster.

    Options/arguments:

         d         Degrees, where valid entries are 90, 180, 270 or the minus
                   values of same, for a counterclockwise rotation
