MPE_Draw_line(4) MPE MPE_Draw_line(4)
MPE_Draw_line - Draws a line on an X11 display
int MPE_Draw_line( handle, x1, y_1, x2, y_2, color )
int x1, y_1, x2, y_2;
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,
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.
