MPE_Draw_line

Draws a line on an X11 display

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.
