NAME

     glutBitmapWidth -- Return the width of a bitmapped character, in pixels.

LIBRARY

     OpenGLUT - bitmapfont

SYNOPSIS

     #include <openglut.h>

     int
     glutBitmapWidth(void *font, int character);

PARAMETERS

      font	 A bitmapped font identifier.

      character  A character code.

DESCRIPTION

     Returns the horizontal OpenGL raster position offset for a  character  in a bitmapped  font.

     It is also an upper bound on the width of the bitmapped glyph for	character,  though not all letters will use their full width, especially
     fixed-width fonts.

     Returns 0 if the  character  is out of the inclusive range [0,255] or if the  font  is invalid.

CAVEATS

     In GLUT, some glyphs could render to the left of the starting position, in some fonts.  OpenGLUT's fonts all position all of their glyphs to
     start at, or to the right of, the initial position.

NAME

       glutBitmapCharacter - renders a bitmap character using OpenGL.

SYNTAX

       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]);
	   }
	 }
