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.
