NAME
glutBitmapString -- Draw a string of bitmapped characters
LIBRARY
OpenGLUT - bitmapfont
SYNOPSIS
#include <openglut.h>
void
glutBitmapString(void *font, const unsigned char *string);
PARAMETERS
font A bitmapped font identifier.
string A NUL-terminated ASCII string.
DESCRIPTION
Draw a string the current OpenGL raster position using a bitmapped font. The raster position is advanced by the width of the string.
The starting raster position is used as the left margin for multi-line strings. Each newline character repositions the raster position at
the beginning of the next line.
Nothing is drawn, and the raster position is unaffected when either:
- font is not a valid OpenGLUT bitmap font
- string is an empty string or NULL pointer
- The current OpenGL raster position is invalid

glutBitmapCharacter(3GLUT) GLUT glutBitmapCharacter(3GLUT)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]);
}
}
