line_type(3G)
NAME
line_type − select line type for all subsequent line primitives
SYNOPSIS
C Syntax:
void line_type(fildes,style);
int fildes, style;
FORTRAN77 Syntax:
subroutine line_type(fildes,style)
integer*4 fildes, style
Pascal Syntax:
procedure line_type(fildes,style:integer);
DESCRIPTION
Input Parameters
fildes Integer file descriptor returned by gopen when an I/O path to a graphic device is opened.
style One of the following:
SOLID
DASH
DOT
DASH_DOT
DASH_DOT_DOT
LONG_DASH
CENTER_DASH
CENTER_DASH_DASH
Discussion
Predefined line types are described below:
| 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. For example, -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.
Wide lines do not support line types.
Some devices do not support this procedure.
DEFAULTS
Solid Lines.
