NAME

glutStrokeCharacter - renders a stroke character using OpenGL.

SYNTAX

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.");
