glutBitmapWidth(3GLUT) GLUT glutBitmapWidth(3GLUT)NAME
glutBitmapWidth - returns the width of a bitmap character, glutBitmapLength returns the length of a bitmap font string.
SYNTAX
#include <GLUT/glut.h>
int glutBitmapWidth(void *font, int character)
int glutBitmapLength(void *font, const unsigned char *string)
ARGUMENTS
font Bitmap font to use. For valid values, see the glutBitmapCharacter description.
character Character to return width of (not confined to 8 bits).
string Text string (8-bit characters), nul terminated.
DESCRIPTION
glutBitmapWidth returns the width in pixels of a bitmap character in a supported bitmap font. While the width of characters in a font may
vary (though fixed width fonts do not vary), the maximum height characteristics of a particular font are fixed.
glutBitmapLength returns the length in pixels of a string (8-bit characters). This length is equivalent to summing all the widths returned
by glutBitmapWidth for each character in the string.

glutStrokeCharacter(3GLUT) GLUT glutStrokeCharacter(3GLUT)NAME
glutStrokeCharacter - renders a stroke character using OpenGL.
SYNTAX
#include <GLUT/glut.h>
void glutStrokeCharacter(void *font, int character);
ARGUMENTS
font Stroke font to use.
character Character to render (not confined to 8 bits).
DESCRIPTION
Without using any display lists, glutStrokeCharacter renders the character in the named stroke font. The available fonts are:
GLUT_STROKE_ROMAN
A proportionally spaced Roman Simplex font for ASCII characters 32 through 127. The maximum top character in the font is 119.05
units; the bottom descends 33.33 units.
GLUT_STROKE_MONO_ROMAN
A mono-spaced spaced Roman Simplex font (same characters as GLUT_STROKE_ROMAN) for ASCII characters 32 through 127. The maximum top
character in the font is 119.05 units; the bottom descends 33.33 units. Each character is 104.76 units wide.
Rendering a nonexistent character has no effect. A glTranslatef is used to translate the current model view matrix to advance the width of
the character.
EXAMPLE
Here is a routine that shows how to render a string of ASCII text with glutStrokeCharacter:
void
output(GLfloat x, GLfloat y, char *text)
{
char *p;
glPushMatrix();
glTranslatef(x, y, 0);
for (p = text; *p; p++)
glutStrokeCharacter(GLUT_STROKE_ROMAN, *p);
glPopMatrix();
}
If you want to draw stroke font text using wide, antialiased lines, use:
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
glEnable(GL_BLEND);
glEnable(GL_LINE_SMOOTH);
glLineWidth(2.0);
output(200, 225, "This is antialiased.");
