glutBitmapCharacter(3GLUT)           GLUT           glutBitmapCharacter(3GLUT)


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
               standard 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
               standard 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]);
           }
         }
