CHARACTER_EXPANSION_FACTOR(3G)

NAME

character_expansion_factor − set the character cell height to width ratio.

SYNOPSIS

C SYNTAX

void character_expansion_factor(fildes,factor);
int fildes;
float factor;

FORTRAN77 SYNTAX

        subroutine character_expansion_factor(fildes,factor)
        integer*4 fildes
        real factor

PASCAL SYNTAX

procedure character_expansion_factor(fildes:integer;
factor: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.
factor
is a deviation factor from the width/height ratio specified with each font.

DISCUSSION

Character_expansion_factor sets the character cell width to (factor)*(character height)*(font width/height ratio). The character_width procedure and the character_expansion_factor procedure both modify the width of a character. The procedure most recently executed defines the character width for subsequently drawn characters.

DEFAULTS

A factor of 1.0.
