NAME
glutStrokeHeight -- Returns the height of a given font.
LIBRARY
OpenGLUT - fonts
SYNOPSIS
#include <openglut.h>
GLfloat
glutStrokeHeight(void *fontID);
PARAMETERS
fontID A GLUT stroked font identifier.
DESCRIPTION
This function reports the height of a font, given by fontID, as a global characteristic of that font.
Returns 0 if fontID is invalid.
CAVEATS
Does not report the height used by individual characters. This may limit its usefulness; perhaps we should change it? (And/or add a new
function.)
TODO
We have discussed adding a "font descender" query. We should go ahead and do it.

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.");
