Detailed Description

Specialization of a path that only contains linear pieces.

Can be created from the existing path of a gfxContext.

Constructor & Destructor Documentation

gfxFlattenedPath::gfxFlattenedPath ( cairo_path_t * aPath ) [protected]

virtual gfxFlattenedPath::~gfxFlattenedPath ( ) [virtual]

gfxPoint gfxFlattenedPath::FindPoint	(	gfxPoint	aOffset,
		gfxFloat *	aAngle = `0L`
	)

Returns a point a certain distance along the path.

Return is first or last point of the path if the requested length offset is outside the range for the path.

Parameters:

	aOffset	offset inpath parameter space (x=length, y=normal offset)
	aAngle	optional - output tangent

gfxFloat gfxFlattenedPath::GetLength ( )

Returns calculated total length of path.
