Constructor & Destructor Documentation

◆ SkPathMeasure() [1/3]

SkPathMeasure::SkPathMeasure ( )

◆ SkPathMeasure() [2/3]

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

Initialize the pathmeasure with the specified 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).

Member Function Documentation

◆ getLength()

SkScalar SkPathMeasure::getLength ( )

Return the total length of the current contour, or 0 if no path is associated (e.g.

resetPath(null))

◆ getMatrix()

bool SkPathMeasure::getMatrix	(	SkScalar	distance,
		SkMatrix *	matrix,
		MatrixFlags	flags = `kGetPosAndTan_MatrixFlag`
	)

Pins distance to 0 <= distance <= getLength(), and then computes the corresponding matrix (by calling getPosTan).

Returns false if there is no path, or a zero-length path was specified, in which case matrix is unchanged.

◆ getPosTan()

bool SkPathMeasure::getPosTan	(	SkScalar	distance,
		SkPoint *	position,
		SkVector *	tangent
	)

Pins distance to 0 <= distance <= getLength(), and then computes the corresponding position and tangent.

Returns false if there is no path, or a zero-length path was specified, in which case position and tangent are unchanged.

◆ getSegment()

bool SkPathMeasure::getSegment	(	SkScalar	startD,
		SkScalar	stopD,
		SkPath *	dst,
		bool	startWithMoveTo
	)

Given a start and stop distance, return in dst the intervening segment(s).

If the segment is zero-length, return false, else return true. startD and stopD are pinned to legal values (0..getLength()). If startD > stopD then return false (and leave dst untouched). Begin the segment with a moveTo if startWithMoveTo is true

◆ isClosed()

bool SkPathMeasure::isClosed ( )

Return true if the current contour is closed()

◆ nextContour()

bool SkPathMeasure::nextContour ( )

Move to the next contour in the path.

Return true if one exists, or false if we're done with the path.

◆ operator=()

SkPathMeasure& SkPathMeasure::operator= ( SkPathMeasure && )
