Detailed Description

Iterates through verb array, and associated SkPoint array and conic weight.

Provides options to treat open contours as closed, and to ignore degenerate data.

Constructor & Destructor Documentation

Iter() [1/2]

SkPath::Iter::Iter

(

)

Initializes SkPath::Iter with an empty SkPath.

next() on SkPath::Iter returns kDone_Verb. Call setPath to initialize SkPath::Iter at a later time.

Returns

SkPath::Iter of empty SkPath

example: https://fiddle.skia.org/c/@Path_Iter_Iter

Iter() [2/2]

SkPath::Iter::Iter	(	const SkPath &	path,
		bool	forceClose
	)

Sets SkPath::Iter to return elements of verb array, SkPoint array, and conic weight in path.

If forceClose is true, SkPath::Iter will add kLine_Verb and kClose_Verb after each open contour. path is not altered.

Parameters

path	SkPath to iterate
forceClose	true if open contours generate kClose_Verb

Returns

SkPath::Iter of path

example: https://fiddle.skia.org/c/@Path_Iter_const_SkPath

Member Function Documentation

conicWeight()

SkScalar SkPath::Iter::conicWeight ( ) const

inline

Returns conic weight if next() returned kConic_Verb.

If next() has not been called, or next() did not return kConic_Verb, result is undefined.

Returns

conic weight for conic SkPoint returned by next()

isClosedContour()

bool SkPath::Iter::isClosedContour

(

)

const

Returns true if subsequent calls to next() return kClose_Verb before returning kMove_Verb.

if true, contour SkPath::Iter is processing may end with kClose_Verb, or SkPath::Iter may have been initialized with force close set to true.

Returns

true if contour is closed

example: https://fiddle.skia.org/c/@Path_Iter_isClosedContour

isCloseLine()

bool SkPath::Iter::isCloseLine ( ) const

inline

Returns true if last kLine_Verb returned by next() was generated by kClose_Verb.

When true, the end point returned by next() is also the start point of contour.

If next() has not been called, or next() did not return kLine_Verb, result is undefined.

Returns

true if last kLine_Verb was generated by kClose_Verb

next()

Verb SkPath::Iter::next

(

SkPoint

pts[4]

)

Returns next SkPath::Verb in verb array, and advances SkPath::Iter.

When verb array is exhausted, returns kDone_Verb.

Zero to four SkPoint are stored in pts, depending on the returned SkPath::Verb.

Parameters

pts	storage for SkPoint data describing returned SkPath::Verb

Returns

next SkPath::Verb from verb array

example: https://fiddle.skia.org/c/@Path_RawIter_next

setPath()

void SkPath::Iter::setPath	(	const SkPath &	path,
		bool	forceClose
	)

Sets SkPath::Iter to return elements of verb array, SkPoint array, and conic weight in path.

If forceClose is true, SkPath::Iter will add kLine_Verb and kClose_Verb after each open contour. path is not altered.

Parameters

path	SkPath to iterate
forceClose	true if open contours generate kClose_Verb

example: https://fiddle.skia.org/c/@Path_Iter_setPath
