NAMEglutStrokeWidth — Returns the width in pixels of a character in a given
font.
LIBRARY
OpenGLUT - fonts
SYNOPSIS
#include <openglut.h>
float
glutStrokeWidth(void *fontID, int character);
PARAMETERS
fontID A GLUT stroked font identifier.
character A character code.
DESCRIPTION
This function reports how far the model space origin will advance if you
putput this character in the font named by fontID. Not all letters
will use their full width, especially in fixed-width fonts.
Returns 0 if character is out of range or if the fontID is invalid.
CAVEATS
Historically, this function has been described as returning a pixel-
width, but was implemented to return the width in model-space units,
rounded to integers. GLUT never resolved this, and freeglut duplicated
the confusion. OpenGLUT has decided to stay in model-space and to return
the unrounded floating point value. An unreleased GLUT 3.8 was supposed
to include glutStrokeWidthf() and glutStrokeLengthf() (note the *f suf‐
fixes), but that is not in wide use.
TODO
Determine if any glyphs are either wider than this function or if they
render outside of the bounding box given by (0,-descent) by
(width,height-descent) .
