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.
