NAME

       MPE_Draw_logic -  Sets logical operation for laying down new pixels

SYNOPSIS

       #include "mpe.h"
       int MPE_Draw_logic( graph, function )
       MPE_XGraph graph;
       int function;

INPUT PARAMETERS

       graph  - MPE graphics handle
       function
              - integer specifying one of the following:
              MPE_LOGIC_COPY - no logic, just copy the pixel
              MPE_LOGIC_XOR  -  xor  the  new  pixel  with  the existing one and many more... see
              mpe_graphics.h

NOTES FOR FORTRAN INTERFACE

       The Fortran interface to this routine is different from its C counterpart and  it  has  an
       additional  argument,  ierr,  at  the end of the argument list, i.e. the returned function
       value (the error code) in C interface is returned as the additional  argument  in  Fortran
       interface.  The Fortran interface is invoked with the CALL statement.

       All  MPI  and  MPE  objects,  MPI_Comm,  MPE_XGraph  and MPE_Color, are of type INTEGER in
       Fortran.
