SYNOPSIS

#include "mpe.h"
int MPE_Draw_line( handle, x1, y_1, x2, y_2, color )
MPE_XGraph handle;
int x1, y_1, x2, y_2;
MPE_Color color;

INPUT PARAMETERS

handle

- MPE graphics handle

x1,y_1

- pixel position of one end of the line to draw. Coordinates are upper-left origin (standard X11)

x2,y_2

- pixel position of the other end of the line to draw. Coordinates are upper-left origin (standard X11)

color

- Color index value. See MPE_MakeColorArray .

By default, the colors MPE_WHITE , MPE_BLACK , MPE_RED , MPE_YELLOW , MPE_GREEN , MPE_CYAN , MPE_BLUE , MPE_MAGENTA , MPE_AQUAMARINE , MPE_FORESTGREEN , MPE_ORANGE , MPE_VIOLET , MPE_BROWN , MPE_PINK , MPE_CORAL and MPE_GRAY are defined.

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.
