Chapter 8 Display and Level Operations

The graphics command provides the user with full control of the type and size
of the map display.  The user may designate that the entire screen width  be
used for the graphics display by entering the optional -f argument.  The
default condition is a normal, TILE 7 (square) map display.  Vectors from any
set, all objects (set 0), attributed objects, or adjacent map vectors (stored
in import levels) may be displayed in any combination as normal or highlighted.
NOTE: The normal color relates to the pen3 = value in the config file; the
highlight color relates to the pen6 = value in the config file.  However, if
normal is displayed over the raster then the color displayed will be the pen7 =
value.  When highlight is displayed over the raster, the color will be the pen8
= value.  When highlight and normal are displayed together, with or without
raster, highlight will dominate (or overwrite) normal (i.e., h + n = h and h +
n + r = h + r).

graphics

    Controls the graphic display.
     
         graphics [+-f] [+-r] [+-nXX] ... [+-hXX] ... [+ c] ...

    Controls the graphic display.  The display is reconfigured each time this
    function is executed.  If no parameters  are specified, the square
    raster-only mode is displayed.  If the map has not been assembled and no
    adjacent map data has been added, then there will be no vectors to
    display.  All options are independent.  If an object fits both the normal
    [+n] and highlight [+h] groups, then it will be displayed highlighted.
    The order of the arguments is not important.  Any number of normal [+-n]
    and/or highlight [+-h] parameter groups may be included.  The [+-c] value
    turns on/off the polygon centroid markers; a polygon may have multiple
    centroids.  If on, the centroid markers will be displayed in the color of
    the corresponding polygon.

    Example(s):

         To activate a full screen-width display, enter:

              graphics +f
          
         To display the vectors in set 12 highlighted, enter:

              graphics +h12
     
         To display (unhighlighted) the imported vector files on level 45,
         enter:
     
              graphics +n45
     
         To reset graphics to powerup status (all vector display off, raster
         display only in the large square graphics area, enter:
     
              graphics
     
         To remove the raster from the display, remove set 16 and import level
         42 from normal display, and add sets 4 and 7 highlighted and import
         vector level 35 (normal), and change the display from full width to
         the square graphics area only, enter:
     
              graphics -r -n16 -n42 +h4 +h7 +n35 -f
