NAME

marker_orientation − define orientation of symbols drawn with marker primitives

SYNOPSIS

C Syntax:

void marker_orientation(fildes,x,y);
int fildes;
float x,y;

FORTRAN77 Syntax:

subroutine marker_orientation(fildes,x,y)
integer*4 fildes
real x,y

Pascal Syntax:

procedure marker_orientation(fildes:integer;x,y:real);

DESCRIPTION

Input Parameters

fildes Integer file descriptor returned by gopen when an I/O path to a graphics device is opened. 

x,y Components of a vector relative to (0.0,0.0) that determines the orientation of subsequent marker symbols.  Vector is specified in vdc coordinates. 

DISCUSSION

The marker_orientation vector defines the slant of marker symbols and is not a rotation.  That is, the orientation vector determines the movement of subsequent marker symbols away from the vertical. 

DEFAULTS

x = 0.0; y = 1.0.
