Renders a stroke character using OpenGL.
Stroke font to use. Without using any display lists, glutStrokeCharacter renders the character in the named stroke font. The available fonts are:
Value | Description |
---|---|
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 Gl.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 text string with glutStrokeCharacter:
private void PrintText(float x, float y, string text) { GL.glPushMatrix(); Gl.glTranslatef(x, y, 0); foreach(char c in text) { Glut.glutStrokeCharacter(Glut.GLUT_STROKE_ROMAN, c); } Gl.glPopMatrix(); }
If you want to draw stroke font text using wide, antialiased lines, use:
Gl.glBlendFunc(Gl.GL_SRC_ALPHA, Gl.GL_ONE_MINUS_SRC_ALPHA); Gl.glEnable(Gl.GL_BLEND); Gl.glEnable(Gl.GL_LINE_SMOOTH); Gl.glLineWidth(2.0f); PrintText(200, 225, "This is antialiased.");
