MPE_Draw_logic - Sets logical operation for laying down new pixels
#include "mpe.h"
int MPE_Draw_logic( graph, function )
MPE_XGraph graph;
int function;
- 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
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.
