LINE_REPEAT_LENGTH(3G)

NAME

line_repeat_length, intline_repeat_length − specify line pattern length for line primitives

SYNOPSIS

C Syntax:

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

void intline_repeat_length(fildes,length);
int fildes,length;

FORTRAN77 Syntax:

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

subroutine intline_repeat_length(fildes,length)
integer*4 fildes,length

Pascal Syntax:

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

procedure intline_repeat_length(fildes,length:integer);

DESCRIPTION

Input Parameters

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

length Repeat length of the line-type pattern measured in virtual device units along the x-direction.

Discussion

This procedure sets the repeat length for polyline and draw output primitives.

There are some device-dependent limitations for setting repeat length. Some raster devices round to the nearest multiple of 16 pixels.

Integer operations are only available when using the INT_XFORM gopen mode. When in INT_XFORM mode, floating point operations are not available for that fildes. Floating point operations are the default, or can be specified with FLOAT_XFORM mode. For a list of integer operations, floating point operations and common operations see the starbase.3g manual page.

DEFAULT

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