marker_orientation(3G)
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 units.
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.
