Constructor & Destructor Documentation

OGLFT::BBox::BBox ( )

inline

Default constructor is all zeros.

Definition at line 176 of file moOGLFT.h.

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.

Definition at line 186 of file moOGLFT.h.

Member Function Documentation

BBox& OGLFT::BBox::operator*= ( double  k )

inline

Scale the bounding box by a constant.

Parameters

k	a constant to scale the bounding box by.

Returns

a reference to oneself.

Definition at line 197 of file moOGLFT.h.

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.
