Member Function Documentation

void osgText::Font::GlyphTexture::addGlyph	(	Glyph *	glyph,
		int	posX,
		int	posY
	)

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.

Reimplemented from osg::Texture2D.

unsigned int osgText::Font::GlyphTexture::getGlyphImageMargin

(

)

const [inline]

bool osgText::Font::GlyphTexture::getSpaceForGlyph	(	Glyph *	glyph,
		int &	posX,
		int &	posY
	)

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.
