NAME

perimeter_repeat_length − determines the size of line type patterns for polygon perimeters. 

SYNOPSIS

C SYNTAX

void perimeter_repeat_length(fildes,length);
int fildes;
float length;

FORTRAN77 SYNTAX

        subroutine perimeter_repeat_length(fildes,length)
        integer*4 fildes
        real length

PASCAL SYNTAX

procedure perimeter_repeat_length(fildes:integer;
length:real);

HP-UX COMPATIBILITY

Level: HP-UX/STANDARD

Origin: ANSI Computer Graphics Interface

DESCRIPTION

INPUT PARAMETERS

fildes
is an integer file descriptor returned by gopen when an I/O path to a graphic device is opened. 
length
is the repeat length of the perimeter type pattern measured in virtual device units along the x-direction.

DISCUSSION

This procedure sets the repeat length for polygon and rectangle output primitive perimeters. 
 
There are some device dependent limitations for setting repeat length. Some raster devices will round to the nearest multiple of 16 pixels.

DEFAULT

repeat length is 1/32 of the default vdc_extent x-axis.
