Resize any per context GLObject buffers to specified size.
Reimplemented from osg::Object.
void osgText::Font::setGlyphImageMargin | ( | unsigned int | margin | ) |

void osgText::Font::setGlyphImageMarginRatio | ( | float | margin | ) |
Set the margin ratio around each glyph, relative to the glyph's size. to ensure that texture filtering doesn't bleed adjacent glyph's into each other. Default margin is 0.05.

void osgText::Font::setMinFilterHint | ( | osg::Texture::FilterMode | mode | ) |
Set the minification texture filter to use when creating the texture to store the glyph images when rendering. Note, this doesn't affect already created Texture Glhph's.
