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.
