glutBitmapCharacter(3GLUT) GLUT glutBitmapCharacter(3GLUT)NAMEglutBitmapCharacter - 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 char‐
acter 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 bit‐
maps 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 bit‐
maps 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 bit‐
maps 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 bit‐
maps 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 bit‐
maps 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 return‐
ing. 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]);
}
}
