◆ addArc()

SkPathBuilder& SkPathBuilder::addArc	(	const SkRect &	oval,
		SkScalar	startAngleDeg,
		SkScalar	sweepAngleDeg
	)

Appends arc to the builder, as the start of new contour.

Arc added is part of ellipse bounded by oval, from startAngle through sweepAngle. Both startAngle and sweepAngle are measured in degrees, where zero degrees is aligned with the positive x-axis, and positive sweeps extends arc clockwise.

If sweepAngle <= -360, or sweepAngle >= 360; and startAngle modulo 90 is nearly zero, append oval instead of arc. Otherwise, sweepAngle values are treated modulo 360, and arc may or may not draw depending on numeric rounding.

Parameters

oval	bounds of ellipse containing arc
startAngleDeg	starting angle of arc in degrees
sweepAngleDeg	sweep, in degrees. Positive is clockwise; treated modulo 360

Returns: reference to this builder

◆ arcTo() [1/3]

SkPathBuilder& SkPathBuilder::arcTo	(	const SkRect &	oval,
		SkScalar	startAngleDeg,
		SkScalar	sweepAngleDeg,
		bool	forceMoveTo
	)

Appends arc to the builder.

Arc added is part of ellipse bounded by oval, from startAngle through sweepAngle. Both startAngle and sweepAngle are measured in degrees, where zero degrees is aligned with the positive x-axis, and positive sweeps extends arc clockwise.

arcTo() adds line connecting the builder's last point to initial arc point if forceMoveTo is false and the builder is not empty. Otherwise, added contour begins with first point of arc. Angles greater than -360 and less than 360 are treated modulo 360.

Parameters

oval	bounds of ellipse containing arc
startAngleDeg	starting angle of arc in degrees
sweepAngleDeg	sweep, in degrees. Positive is clockwise; treated modulo 360
forceMoveTo	true to start a new contour with arc

Returns: reference to the builder

◆ arcTo() [2/3]

SkPathBuilder& SkPathBuilder::arcTo	(	SkPoint	p1,
		SkPoint	p2,
		SkScalar	radius
	)

Appends arc to SkPath, after appending line if needed.

Arc is implemented by conic weighted to describe part of circle. Arc is contained by tangent from last SkPath point to p1, and tangent from p1 to p2. Arc is part of circle sized to radius, positioned so it touches both tangent lines.

If last SkPath SkPoint does not start arc, arcTo() appends connecting line to SkPath. The length of vector from p1 to p2 does not affect arc.

Arc sweep is always less than 180 degrees. If radius is zero, or if tangents are nearly parallel, arcTo() appends line from last SkPath SkPoint to p1.

arcTo() appends at most one line and one conic. arcTo() implements the functionality of PostScript arct and HTML Canvas arcTo.

Parameters

p1	SkPoint common to pair of tangents
p2	end of second tangent
radius	distance from arc to circle center

Returns: reference to SkPath

◆ arcTo() [3/3]

SkPathBuilder& SkPathBuilder::arcTo	(	SkPoint	r,
		SkScalar	xAxisRotate,
		ArcSize	largeArc,
		SkPathDirection	sweep,
		SkPoint	xy
	)

Appends arc to SkPath.

Arc is implemented by one or more conic weighted to describe part of oval with radii (r.fX, r.fY) rotated by xAxisRotate degrees. Arc curves from last SkPath SkPoint to (xy.fX, xy.fY), choosing one of four possible routes: clockwise or counterclockwise, and smaller or larger.

Arc sweep is always less than 360 degrees. arcTo() appends line to xy if either radii are zero, or if last SkPath SkPoint equals (xy.fX, xy.fY). arcTo() scales radii r to fit last SkPath SkPoint and xy if both are greater than zero but too small to describe an arc.

arcTo() appends up to four conic curves. arcTo() implements the functionality of SVG arc, although SVG sweep-flag value is opposite the integer value of sweep; SVG sweep-flag uses 1 for clockwise, while kCW_Direction cast to int is zero.

Parameters

r	radii on axes before x-axis rotation
xAxisRotate	x-axis rotation in degrees; positive values are clockwise
largeArc	chooses smaller or larger arc
sweep	chooses clockwise or counterclockwise arc
xy	end of arc

Returns: reference to SkPath
