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.

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.");
