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.
