)

virtual void osgText::Font::GlyphTexture::apply ( osg::State & state ) const [virtual]

Bind the texture object.
If the texture object hasn't already been compiled, create the texture mipmap levels.
Reimplemented from osg::Texture2D.

const char* osgText::Font::GlyphTexture::className ( ) const [inline, virtual]

Return the name of the attribute's class type.

Reimplemented from osg::Texture.

virtual int osgText::Font::GlyphTexture::compare ( const osg::StateAttribute & rhs ) const [virtual]

return -1 if *this < *rhs, 0 if *this==*rhs, 1 if *this>*rhs.

void osgText::Font::GlyphTexture::setGlyphImageMargin ( unsigned int margin ) [inline]

Set the margin around each glyph, to ensure that texture filtering doesn't bleed adjacent glyph's into each other.
