		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]

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

Parameters:

glyph

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.

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.
