MPE_Draw_logicSets 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
Notes For Fortran InterfaceThe 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.
