STRINGSIZE(3)		   Library Functions Manual		 STRINGSIZE(3)

NAME
       stringsize, stringwidth,	stringnwidth, runestringsize, runestringwidth,
       runestringnwidth	- graphical size of strings

SYNOPSIS
       #include	<u.h>
       #include	<libc.h>
       #include	<draw.h>

       Point stringsize(Font *f, char *s)

       int   stringwidth(Font *f, char *s)

       int   stringnwidth(Font *f, char	*s, int	n)

       Point runestringsize(Font *f, Rune *s)

       int   runestringwidth(Font *f, Rune *s)

       int   runestringnwidth(Font *f, Rune *s,	int n)

DESCRIPTION
       These routines compute the geometrical extent of	character strings when
       drawn  on the display.  The most	straightforward, stringsize, returns a
       Point representing the vector from upper	left to	 lower	right  of  the
       NUL-terminated  string s	drawn in font f.  Stringwidth returns just the
       x component.  Stringnwidth returns the width of the first n  characters
       of s.

       The  routines beginning with rune are analogous,	but accept an array of
       runes rather than UTF-encoded bytes.

FILES
       /lib/font/bit	directory of fonts

SOURCE
       /usr/local/plan9/src/libdraw

SEE ALSO
       addpt(3),  cachechars(3),  subfont(3),  draw(3),	  draw(3),   image(7),
       font(7)

DIAGNOSTICS
       Because strings are loaded dynamically, these routines may generate I/O
       to the server and produce calls to the graphics error function.
