Contents of this diskette:
 
    FARBE2D.FOR      Source of package FARB-E-2D including
                     a testdriver calling FARBE, the highest level.
                     It should run without any changes on any
                     system where a GKS (Graphical Kernel System)
                     of (at least) Level 1a is installed.
                     Note that the fill area representations
                     selected by calls of routine GSFAR may
                     not be available on all workstations.
 
           When making adaptions for other graphic software,
           note the following:
 
       -   Replace the calls for opening and closing the graphic
           system GOPEN and GCLOSE in the testdriver TESTFA.
 
       -   Replace the calls to GPL and GTEXT in subroutines
           FARBE and FRBLGD. GPL plots a polyline (polygone),
           and GTEXT plots text. The parameters of GTEXT are
           identical with CALCOMP-subroutine SYMBOL.
 
       -   Adapt the user-supplied subroutine USRPLT or write
           your own. In USRPLT calls for area filling or/and
           line plotting must be set up.
 
 
 
    TEST2D.FOR        is a file with the source of a test driver
                      testing numerically critical situations.
                      (Fig. 8 of the corresponding paper)
                      It calls FARB2D directly. FARB2D is the
                      second level of the user interface.
 
 
    GKSIBM.FOR        contains the source code of some subroutines
                      that have to be replaced in file FARBE2D.FOR
                      when using IBM GKS, version 1.0, and the
                      Professional Fortran Compiler on a IBM PC/AT.
                      Because this IBM GKS does not support
                      variable character heights for most displays
                      (only certain hardware character heights)
                      the FARB-E-2D Logo may be displayed incorrectly.
