Detailed Description

FTBBox is a convenience class for handling bounding boxes.

Definition at line 42 of file FTBBox.h.

Constructor & Destructor Documentation

FTBBox() [1/4]

FTBBox::FTBBox ( )

inline

Default constructor.

Bounding box is set to zero.

Definition at line 48 of file FTBBox.h.

FTBBox() [2/4]

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() [3/4]

FTBBox::FTBBox ( FTPoint  l, FTPoint  u  )

inline

Constructor.

Definition at line 64 of file FTBBox.h.

FTBBox() [4/4]

FTBBox::FTBBox ( FT_GlyphSlot  glyph )

inline

Constructor.

Extracts a bounding box from a freetype glyph. Uses the control box for the glyph. FT_Glyph_Get_CBox()

Parameters

glyph

A freetype glyph

Definition at line 75 of file FTBBox.h.

~FTBBox()

FTBBox::~FTBBox ( )

inline

Destructor.

Definition at line 93 of file FTBBox.h.

Member Function Documentation

Invalidate()

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.

IsValid()

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.

Lower()

FTPoint const FTBBox::Lower ( ) const

inline

Definition at line 165 of file FTBBox.h.

Referenced by FTFont::BBox(), and FTFont::BBox().

operator+=()

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.

operator|=()

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.
