CHARACTER_WIDTH(3G)

NAME

character_width − specify character width

SYNOPSIS

C Syntax:

void character_width(fildes,width);
int fildes;
float width;

void dccharacter_width(fildes,dcwidth);
int fildes,dcwidth;

FORTRAN77 Syntax:

subroutine character_width(fildes,width)
integer*4 fildes
real width

subroutine dccharacter_width(fildes,dcwidth)
integer*4 fildes,dcwidth

Pascal Syntax:

procedure character_width(fildes:integer;width:real);

procedure dccharacter_width(fildes,dcwidth:integer);

DESCRIPTION

Input Parameters

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

width Width of a text character measured in Virtual Device Coordinates along the baseline.

dcwidth Width of a text character measured in Device Coordinates along the baseline.

Discussion

Character_width specifies the width of subsequently drawn characters. The character_expansion_factor and character_width procedures both modify the width of a character. The procedure most recently executed defines the character width for subsequently drawn characters.

Character width values are independent of character height values.

Beware:

If vdc_extent is changed, the character width is recomputed using the new VDC extent and the last character width set, or the default (0.02) if no previous calls to character_width were made.

DEFAULTS

None, character width is defined by the default character expansion factor of 1.0.
