glutStrokeWidth(3GLUT)						       GLUT						    glutStrokeWidth(3GLUT)

NAME

       glutStrokeWidth returns the width of a stroke character, glutStrokeLength returns the length of a stroke font string.

SYNTAX

       int glutStrokeWidth(void *font, int character);
       int glutStrokeLength(void *font, const unsigned char *string);

ARGUMENTS

       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), nul terminated.

DESCRIPTION

       glutStrokeWidth	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.

       glutStrokeLength returns the length in modeling units of a string (8-bit characters).  This length is equivalent to summing all the  widths
       returned by glutStrokeWidth for each character in the string.

NAME

     glutStrokeWidth -- 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 let-
     ters 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 suffixes), 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)  .
