Constructor & Destructor Documentation

OGLFT::BBox::BBox ( FT_BBox ft_bbox ) [inline]

(Partially) initialize a BBox from a FreeType bounding box member. (The advancement is initialized to zero by its default constructor). Parameters: ft_bbox   a FreeType bounding box as retrieved from FT_Glyph_Get_CBox.

Member Function Documentation

BBox & OGLFT::BBox::operator+= ( const BBox & b ) [inline]

Merge a bounding box into the current one (not really addition). Each time a BBox is "added", the current BBox is expanded to include the metrics of the new BBox. May only work for horizontal fonts, though. Parameters: b   the bounding box to merge. Returns: a reference to oneself.
