MPE_Add_RGB_color - Adds a color to the colormap given its RGB values

#include "mpe.h" 
int MPE_Add_RGB_color( graph, red, green, blue, mapping )
MPE_XGraph graph;
int red, green, blue;
MPE_Color *mapping;

graph

- MPE graphics handle

red, green, blue

- color levels from 0 to 65535

mapping

- index of the new color

-1

- maxcolors too large (equal to numcolors)

MPE_SUCCESS

- successful

mapping

- index of the new color

This call adds a color cell to X11's color table, increments maxcolors (the index), and writes it to the mapping parameter.

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.
