NAME

perimeter_type − select line type for subsequent polygon perimeters

SYNOPSIS

C Syntax:

void perimeter_type(fildes,style);
int fildes,style;

FORTRAN77 Syntax:

subroutine perimeter_type(fildes,style)
integer*4 fildes,style

Pascal Syntax:

procedure perimeter_type(fildes,style:integer);

DESCRIPTION

Input Parameters

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

style One of the following:

SOLID
DASH
DOT
DASH_DOT
DASH_DOT_DOT
LONG_DASH
CENTER_DASH
CENTER_DASH_DASH

Discussion

The following perimeter types are pre-defined:
 

Index   Name                    Approximate Pattern
 0       SOLID                   Solid
1       DASH                    .25 .50 .25
2       DOT                     4-8 dots per repeat length
3       DASH_DOT                .4 .1 dot .1 .35
4       DASH_DOT_DOT            .35 .1 dot .1 dot .1 .35
5       LONG_DASH               .375 .25 .375
6       CENTER_DASH             .35 .1 .1 .1 .35
7       CENTER_DASH_DASH        .25 .1 .1 .1 .1 .1 .25

 
Negative style values are device-dependent.  Thus, −1 is a point plot on a terminal.

Continuity between separate but graphically connected polyline or line segments is not guaranteed. 

The pattern is restarted each time this procedure is executed. 

Some devices do not support this procedure. 

DEFAULTS

Solid Lines.
