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)  .

NAME

       glutBitmapCharacter - renders a bitmap character using OpenGL.

SYNTAX

       #include <GLUT/glut.h>

       void glutBitmapCharacter(void *font, int character);

ARGUMENTS

       font	 Bitmap font to use.

       character Character to render (not confined to 8 bits).

DESCRIPTION

       Without using any display lists, glutBitmapCharacter renders the character in the named bitmap font. The available fonts are:

       GLUT_BITMAP_8_BY_13
	       A fixed width font with every character fitting in an 8 by 13 pixel rectangle. The exact bitmaps to be used is defined by the stan-
	       dard X glyph bitmaps for the X font named:

	       -misc-fixed-medium-r-normal--13-120-75-75-C-80-iso8859-1

       GLUT_BITMAP_9_BY_15
	       A fixed width font with every character fitting in an 9 by 15 pixel rectangle. The exact bitmaps to be used is defined by the stan-
	       dard X glyph bitmaps for the X font named:

	       -misc-fixed-medium-r-normal--15-140-75-75-C-90-iso8859-1

       GLUT_BITMAP_TIMES_ROMAN_10
	       A  10-point proportional spaced Times Roman font. The exact bitmaps to be used is defined by the standard X glyph bitmaps for the X
	       font named:

	       -adobe-times-medium-r-normal--10-100-75-75-p-54-iso8859-1

       GLUT_BITMAP_TIMES_ROMAN_24
	       A 24-point proportional spaced Times Roman font. The exact bitmaps to be used is defined by the standard X glyph bitmaps for the  X
	       font named:

	       -adobe-times-medium-r-normal--24-240-75-75-p-124-iso8859-1

       GLUT_BITMAP_HELVETICA_10
	       A  10-point  proportional  spaced Helvetica font. The exact bitmaps to be used is defined by the standard X glyph bitmaps for the X
	       font named:

	       -adobe-helvetica-medium-r-normal--10-100-75-75-p-56-iso8859-1

       GLUT_BITMAP_HELVETICA_12
	       A 12-point proportional spaced Helvetica font. The exact bitmaps to be used is defined by the standard X glyph bitmaps  for  the  X
	       font named:

	       -adobe-helvetica-medium-r-normal--12-120-75-75-p-67-iso8859-1

       GLUT_BITMAP_HELVETICA_18
	       A  18-point  proportional  spaced Helvetica font. The exact bitmaps to be used is defined by the standard X glyph bitmaps for the X
	       font named:

	       -adobe-helvetica-medium-r-normal--18-180-75-75-p-98-iso8859-1

       Rendering a nonexistent character has no effect.  glutBitmapCharacter automatically sets the OpenGL unpack pixel  storage  modes  it  needs
       appropriately  and  saves  and  restores the previous modes before returning. The generated call to glBitmap will adjust the current raster
       position based on the width of the character.

EXAMPLE

       Here is a routine that shows how to render a string of ASCII text with glutBitmapCharacter:

	 void
	 output(int x, int y, char *string)
	 {
	   int len, i;

	   glRasterPos2f(x, y);
	   len = (int) strlen(string);
	   for (i = 0; i < len; i++) {
	     glutBitmapCharacter(GLUT_BITMAP_HELVETICA_18, string[i]);
	   }
	 }
