SkContourMeasureIter() [2/3]

SkContourMeasureIter::SkContourMeasureIter	(	const SkPath &	path,
		bool	forceClosed,
		SkScalar	resScale = 1
	)

Initialize the Iter with a path. The parts of the path that are needed are copied, so the client is free to modify/delete the path after this call.

resScale controls the precision of the measure. values > 1 increase the precision (and possibly slow down the computation).

next()

sk_sp< SkContourMeasure > SkContourMeasureIter::next

(

)

Iterates through contours in path, returning a contour-measure object for each contour in the path. Returns null when it is done.

This only returns non-zero length contours, where a contour is the segments between a kMove_Verb and either ...

• the next kMove_Verb
• kClose_Verb (1 or more)
• kDone_Verb If it encounters a zero-length contour, it is skipped.

reset()

void SkContourMeasureIter::reset	(	const SkPath &	path,
		bool	forceClosed,
		SkScalar	resScale = 1
	)

Reset the Iter with a path. The parts of the path that are needed are copied, so the client is free to modify/delete the path after this call.

Assign a new path, or null to have none.
