SYNOPSIS

subroutine prefposition(x, y)

     integer,intent(in) :: x, y

DESCRIPTION

Specify the preferred position of the window opened by the *next* vinit in raster units or units of resolution, depending on the output device. The physical size of the units are generally device-specific -- For X11 Windows and PPM pixmaps the values would represent rasters. For vector output devices the number of "rasters" per inch varies.

EXAMPLES

Sample program:

     program demo_prefposition
     use M_draw, only    : prefsize, vinit, ortho2, clear, getkey
     use M_draw, only    : prefposition, move2, draw2, vexit, color
     use M_draw,    only  : D_BLACK,   D_WHITE
     use M_draw,    only  : D_RED,     D_GREEN,    D_BLUE
     use M_draw,    only  : D_YELLOW,  D_MAGENTA,  D_CYAN
     implicit none
     integer :: ipaws

     call prefsize(60,40)
     call prefposition(100,100)

     call vinit(’ ’)         ! start graphics using device $M_DRAW_DEVICE
     call ortho2(-300.0,300.0,-200.0,200.0)
     call color(D_BLACK)
     call clear()
     call color(D_RED)
     call move2(-300.0,-200.0)
     call draw2(300.0,200.0)
     call move2(300.0,-200.0)
     call draw2(-300.0,200.0)
     ipaws=getkey()
     call vexit()

     end program demo_prefposition
