Chapter 9 Input Modes

decrement

Adds a point to the contour attribute profile.

         decrement x y

    This command adds a point to the contour attribute profile.  This function
    is meaningful only when atrbt_contur graphics input mode is active.  In all
    other modes, it behaves exactly like the continue command.  All vectorized
    line crossed from the last point on the profile up to the decrement point
    will be assigned a numeric attribute in decrements of the contour interval
    (stored in the header file).

    Options/arguments:

         x         X raster coordinate of point
         y         Y raster coordinate of point

    Example(s):

    To assign attributes to contour lines which are incrementally downhill from
    a previous atrbt_contur, start, continue or increment command, enter:

         decrement x y
