Default constructor. Bounding box is set to zero. Definition at line 48 of file FTBBox.h.

FTBBox::FTBBox (  float  lx, float  ly, float  lz, float  ux, float  uy, float  uz )  [inline]

Constructor. Definition at line 56 of file FTBBox.h.

FTBBox::FTBBox (  FTPoint  l, FTPoint  u )  [inline]

Constructor. Definition at line 64 of file FTBBox.h.

FTBBox::FTBBox (  FT_GlyphSlot  glyph  )  [inline]

Member Function Documentation

void FTBBox::Invalidate (   )  [inline]

Mark the bounds invalid by setting all lower dimensions greater than the upper dimensions. Definition at line 100 of file FTBBox.h.

bool FTBBox::IsValid (   )  [inline]

Determines if this bounding box is valid. Returns: True if all lower values are <= the corresponding upper values. Definition at line 112 of file FTBBox.h.

FTPoint const FTBBox::Lower (   )  const [inline]

Definition at line 165 of file FTBBox.h. Referenced by FTFont::BBox().

FTBBox& FTBBox::operator+= (  const FTPoint  vector  )  [inline]

Move the Bounding Box by a vector. Parameters: vector  The vector to move the bbox in 3D space. Definition at line 124 of file FTBBox.h.

FTBBox& FTBBox::operator|= (  const FTBBox &  bbox  )  [inline]

Combine two bounding boxes. The result is the smallest bounding box containing the two original boxes. Parameters: bbox  The bounding box to merge with the second one. Definition at line 138 of file FTBBox.h. References lower, upper, FTPoint::X(), FTPoint::Y(), and FTPoint::Z().
