| <table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td> |
| |
| These routines compute the geometrical extent of character strings |
| when drawn on the display. The most straightforward, <tt><font size=+1>stringsize</font></tt>, |
| returns a <tt><font size=+1>Point</font></tt> representing the vector from upper left to lower |
| right of the NUL-terminated string <i>s</i> drawn in font <i>f</i>. <tt><font size=+1>Stringwidth</font></tt> |
| returns just the <i>x</i> component. |
| <tt><font size=+1>Stringnwidth</font></tt> returns the width of the first <i>n</i> characters of <i>s</i>. |
| |
| <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> |
| |
| The routines beginning with <tt><font size=+1>rune</font></tt> are analogous, but accept an |
| array of runes rather than UTF-encoded bytes.<br> |

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