| Variables | Description |
|---|---|
| font |
Stroke font to use. For valid values, see the
glutStrokeWidth
description.
|
| character |
Character to return width of (not confined to 8 bits).
|
| string |
Text string (8-bit characters), null terminated.

Description
glutStrokeWidthf
returns the width in modeling units of a stroke character in a supported stroke
font. While the width of characters in a font may vary (though fixed width fonts do not vary), the maximum height
characteristics of a particular font are fixed.
glutStrokeLengthf
returns the length in modeling units of a string (8-bit characters). This length
is equivalent to summing all the widths returned by
glutStrokeWidthf
for each character in the
string.
Bugs
The deprecated
glutStrokeWidth
and
glutStrokeLength
routines return an
integer rather than a float. Newer GLUT programs should use the newer float-returning routine
glutStrokeWidthf
and
glutStrokeLengthf
. Note that these newer float routines
do not exist in implementations prior to GLUT 3.8. Also, the
glutStrokeLength
routine summed
integerized character widths so it underestimated the length of strings prior to GLUT 3.8, but the implementation of
glutStrokeLength
in GLUT 3.8 and beyond sums the character widths for the strings in a float
(though
glutStrokeLength
still returns an integer).
