SkPath Reference
===
# <a name='Path'>Path</a>
<a href='#Path'>Path</a> contains <a href='undocumented#Line'>Lines</a> and <a href='undocumented#Curve'>Curves</a> which can be stroked or filled. <a href='#Contour'>Contour</a> is
composed of a series of connected <a href='undocumented#Line'>Lines</a> and <a href='undocumented#Curve'>Curves</a>. <a href='#Path'>Path</a> may contain zero,
one, or more <a href='#Contour'>Contours</a>.
Each <a href='undocumented#Line'>Line</a> and <a href='undocumented#Curve'>Curve</a> are described by <a href='#SkPath_Verb'>Verb</a>, <a href='SkPoint_Reference#Point'>Points</a>, and optional <a href='#Conic_Weight'>Conic Weight</a>.
Each pair of connected <a href='undocumented#Line'>Lines</a> and <a href='undocumented#Curve'>Curves</a> share common <a href='SkPoint_Reference#Point'>Point</a>; for instance, <a href='#Path'>Path</a>
containing two connected <a href='undocumented#Line'>Lines</a> are described the <a href='#SkPath_Verb'>Verb</a> sequence:
<a href='#SkPath_kMove_Verb'>SkPath::kMove Verb</a>, <a href='#SkPath_kLine_Verb'>SkPath::kLine Verb</a>, <a href='#SkPath_kLine_Verb'>SkPath::kLine Verb</a>; and a <a href='SkPoint_Reference#Point'>Point</a> sequence
with three entries, sharing
the middle entry as the end of the first <a href='undocumented#Line'>Line</a> and the start of the second <a href='undocumented#Line'>Line</a>.
<a href='#Path'>Path</a> components <a href='#Arc'>Arc</a>, <a href='SkRect_Reference#Rect'>Rect</a>, <a href='SkRRect_Reference#RRect'>Round Rect</a>, <a href='undocumented#Circle'>Circle</a>, and <a href='undocumented#Oval'>Oval</a> are composed of
<a href='undocumented#Line'>Lines</a> and <a href='undocumented#Curve'>Curves</a> with as many <a href='#Verb'>Verbs</a> and <a href='SkPoint_Reference#Point'>Points</a> required
for an exact description. Once added to <a href='#Path'>Path</a>, these components may lose their
identity; although <a href='#Path'>Path</a> can be inspected to determine if it describes a single
<a href='SkRect_Reference#Rect'>Rect</a>, <a href='undocumented#Oval'>Oval</a>, <a href='SkRRect_Reference#RRect'>Round Rect</a>, and so on.
### Example
<div><fiddle-embed name="93887af0c1dac49521972698cf04069c"><div><a href='#Path'>Path</a> contains three <a href='#Contour'>Contours</a>: <a href='undocumented#Line'>Line</a>, <a href='undocumented#Circle'>Circle</a>, and <a href='#Quad'>Quad</a>. <a href='undocumented#Line'>Line</a> is stroked but
not filled. <a href='undocumented#Circle'>Circle</a> is stroked and filled; <a href='undocumented#Circle'>Circle</a> stroke forms a loop. <a href='#Quad'>Quad</a>
is stroked and filled, but since it is not closed, <a href='#Quad'>Quad</a> does not stroke a loop.
</div></fiddle-embed></div>
<a href='#Path'>Path</a> contains a <a href='#Fill_Type'>Fill Type</a> which determines whether overlapping <a href='#Contour'>Contours</a>
form fills or holes. <a href='#Fill_Type'>Fill Type</a> also determines whether area inside or outside
<a href='undocumented#Line'>Lines</a> and <a href='undocumented#Curve'>Curves</a> is filled.
### Example
<div><fiddle-embed name="36a995442c081ee779ecab2962d36e69"><div><a href='#Path'>Path</a> is drawn filled, then stroked, then stroked and filled.
</div></fiddle-embed></div>
<a href='#Path'>Path</a> contents are never shared. Copying <a href='#Path'>Path</a> by value effectively creates
a new <a href='#Path'>Path</a> independent of the original. Internally, the copy does not duplicate
its contents until it is edited, to reduce memory use and improve performance.
## <a name='Contour'>Contour</a>
<a href='#Contour'>Contour</a> contains one or more <a href='#Verb'>Verbs</a>, and as many <a href='SkPoint_Reference#Point'>Points</a> as
are required to satisfy <a href='#Verb_Array'>Verb Array</a>. First <a href='#SkPath_Verb'>Verb</a> in <a href='#Path'>Path</a> is always
<a href='#SkPath_kMove_Verb'>SkPath::kMove Verb</a>; each <a href='#SkPath_kMove_Verb'>SkPath::kMove Verb</a> that follows starts a new <a href='#Contour'>Contour</a>.
### Example
<div><fiddle-embed name="0374f2dcd7effeb1dd435205a6c2de6f"><div>Each <a href='#SkPath_moveTo'>SkPath::moveTo</a> starts a new <a href='#Contour'>Contour</a>, and content after <a href='#SkPath_close'>SkPath::close()</a>
also starts a new <a href='#Contour'>Contour</a>. Since <a href='#SkPath_conicTo'>SkPath::conicTo</a> is not preceded by
<a href='#SkPath_moveTo'>SkPath::moveTo</a>, the first <a href='SkPoint_Reference#Point'>Point</a> of the third <a href='#Contour'>Contour</a> starts at the last <a href='SkPoint_Reference#Point'>Point</a>
of the second <a href='#Contour'>Contour</a>.
</div></fiddle-embed></div>
If final <a href='#SkPath_Verb'>Verb</a> in <a href='#Contour'>Contour</a> is <a href='#SkPath_kClose_Verb'>SkPath::kClose Verb</a>, <a href='undocumented#Line'>Line</a> connects <a href='#Last_Point'>Last Point</a> in
<a href='#Contour'>Contour</a> with first <a href='SkPoint_Reference#Point'>Point</a>. A closed <a href='#Contour'>Contour</a>, stroked, draws
<a href='SkPaint_Reference#Stroke_Join'>Paint Stroke Join</a> at <a href='#Last_Point'>Last Point</a> and first <a href='SkPoint_Reference#Point'>Point</a>. Without <a href='#SkPath_kClose_Verb'>SkPath::kClose Verb</a>
as final <a href='#SkPath_Verb'>Verb</a>, <a href='#Last_Point'>Last Point</a> and first <a href='SkPoint_Reference#Point'>Point</a> are not connected; <a href='#Contour'>Contour</a>
remains open. An open <a href='#Contour'>Contour</a>, stroked, draws <a href='SkPaint_Reference#Stroke_Cap'>Paint Stroke Cap</a> at
<a href='#Last_Point'>Last Point</a> and first <a href='SkPoint_Reference#Point'>Point</a>.
### Example
<div><fiddle-embed name="7a1f39b12d2cd8b7f5b1190879259cb2"><div><a href='#Path'>Path</a> is drawn stroked, with an open <a href='#Contour'>Contour</a> and a closed <a href='#Contour'>Contour</a>.
</div></fiddle-embed></div>
## <a name='Contour_Zero_Length'>Contour Zero Length</a>
<a href='#Contour'>Contour</a> length is distance traveled from first <a href='SkPoint_Reference#Point'>Point</a> to <a href='#Last_Point'>Last Point</a>,
plus, if <a href='#Contour'>Contour</a> is closed, distance from <a href='#Last_Point'>Last Point</a> to first <a href='SkPoint_Reference#Point'>Point</a>.
Even if <a href='#Contour'>Contour</a> length is zero, stroked <a href='undocumented#Line'>Lines</a> are drawn if <a href='SkPaint_Reference#Stroke_Cap'>Paint Stroke Cap</a>
makes them visible.
### Example
<div><fiddle-embed name="62848df605af6258653d9e16b27d8f7f"></fiddle-embed></div>
# <a name='SkPath'>Class SkPath</a>
<a href='#Path'>Paths</a> contain geometry. <a href='#Path'>Paths</a> may be empty, or contain one or more <a href='#Verb'>Verbs</a> that
outline a figure. <a href='#Path'>Path</a> always starts with a move verb to a <a href='undocumented#Cartesian_Coordinate'>Cartesian Coordinate</a>,
and may be followed by additional verbs that add lines or curves.
Adding a close verb makes the geometry into a continuous loop, a closed contour.
<a href='#Path'>Paths</a> may contain any number of contours, each beginning with a move verb.
<a href='#Path'>Path</a> contours may contain only a move verb, or may also contain lines,
<a href='#Quad'>Quadratic Beziers</a>, <a href='#Conic'>Conics</a>, and <a href='#Cubic'>Cubic Beziers</a>. <a href='#Path'>Path</a> contours may be open or
closed.
When used to draw a filled area, <a href='#Path'>Path</a> describes whether the fill is inside or
outside the geometry. <a href='#Path'>Path</a> also describes the winding rule used to fill
overlapping contours.
Internally, <a href='#Path'>Path</a> lazily computes metrics likes bounds and convexity. Call
<a href='#SkPath_updateBoundsCache'>SkPath::updateBoundsCache</a> to make <a href='#Path'>Path</a> thread safe.

Returns true if <a href='#Path'>Paths</a> contain equal <a href='#Verb'>Verbs</a> and equal <a href='#Conic_Weight'>Weights</a>.
If <a href='#Path'>Paths</a> contain one or more <a href='#Conic'>Conics</a>, the <a href='#Conic_Weight'>Weights</a> must match.
<a href='#SkPath_conicTo'>conicTo</a> may add different <a href='#Verb'>Verbs</a> depending on <a href='#Conic_Weight'>Conic Weight</a>, so it is not
trivial to interpolate a pair of <a href='#Path'>Paths</a> containing <a href='#Conic'>Conics</a> with different

</pre>
Interpolates between <a href='#Path'>Paths</a> with <a href='#Point_Array'>Point Array</a> of equal size.
Copy <a href='#Verb_Array'>Verb Array</a> and <a href='#Conic_Weight'>Weights</a> to <a href='#SkPath_interpolate_out'>out</a>, and set <a href='#SkPath_interpolate_out'>out</a> <a href='#Point_Array'>Point Array</a> to a weighted
average of this <a href='#Point_Array'>Point Array</a> and <a href='#SkPath_interpolate_ending'>ending</a> <a href='#Point_Array'>Point Array</a>, using the formula:
(<a href='#Path'>Path</a> <a href='SkPoint_Reference#Point'>Point</a> * <a href='#SkPath_interpolate_weight'>weight</a>) + <a href='#SkPath_interpolate_ending'>ending</a> <a href='SkPoint_Reference#Point'>Point</a> * (1 - <a href='#SkPath_interpolate_weight'>weight</a>)
.
<a href='#SkPath_interpolate_weight'>weight</a> is most useful when between zero (<a href='#SkPath_interpolate_ending'>ending</a> <a href='#Point_Array'>Point Array</a>) and
one (this <a href='#Point_Array'>Point Array</a>); will work with values outside of this
range.
<a href='#SkPath_interpolate'>interpolate</a> returns false and leaves <a href='#SkPath_interpolate_out'>out</a> unchanged if <a href='#Point_Array'>Point Array</a> is not
the same size as <a href='#SkPath_interpolate_ending'>ending</a> <a href='#Point_Array'>Point Array</a>. Call <a href='#SkPath_isInterpolatable'>isInterpolatable</a> to check <a href='#Path'>Path</a>

<a href='SkRect_Reference#SkRect'>SkRect</a> <a href='#SkPath_computeTightBounds'>computeTightBounds</a>() const
</pre>
Returns minimum and maximum axes values of the lines and curves in <a href='#Path'>Path</a>.
Returns (0, 0, 0, 0) if <a href='#Path'>Path</a> contains no points.
Returned bounds width and height may be larger or smaller than area affected
when <a href='#Path'>Path</a> is drawn.

<a href='#Contour'>Contours</a>.
Behaves identically to <a href='#SkPath_getBounds'>getBounds</a> when <a href='#Path'>Path</a> contains
only lines. If <a href='#Path'>Path</a> contains curves, computed bounds includes
the maximum extent of the <a href='#Quad'>Quad</a>, <a href='#Conic'>Conic</a>, or <a href='#Cubic'>Cubic</a>; is slower than <a href='#SkPath_getBounds'>getBounds</a>;

## <a name='Conic'>Conic</a>
<a href='#Conic'>Conic</a> describes a conical section: a piece of an ellipse, or a piece of a
parabola, or a piece of a hyperbola. <a href='#Conic'>Conic</a> begins at a start <a href='SkPoint_Reference#Point'>Point</a>,
curves towards a control <a href='SkPoint_Reference#Point'>Point</a>, and then curves to an end <a href='SkPoint_Reference#Point'>Point</a>. The influence
of the control <a href='SkPoint_Reference#Point'>Point</a> is determined by <a href='#Conic_Weight'>Conic Weight</a>.
Each <a href='#Conic'>Conic</a> in <a href='#Path'>Path</a> adds two <a href='SkPoint_Reference#Point'>Points</a> and one <a href='#Conic_Weight'>Conic Weight</a>. <a href='#Conic_Weight'>Conic Weights</a> in <a href='#Path'>Path</a>
may be inspected with <a href='#SkPath_Iter'>Iter</a>, or with <a href='#SkPath_RawIter'>RawIter</a>.
## <a name='Conic_Weight'>Conic Weight</a>
<a href='#Conic_Weight'>Weight</a> determines both the strength of the control <a href='SkPoint_Reference#Point'>Point</a> and the type of <a href='#Conic'>Conic</a>.
<a href='#Conic_Weight'>Weight</a> varies from zero to infinity. At zero, <a href='#Conic_Weight'>Weight</a> causes the control <a href='SkPoint_Reference#Point'>Point</a> to
have no effect; <a href='#Conic'>Conic</a> is identical to a line segment from start <a href='SkPoint_Reference#Point'>Point</a> to end
point. If <a href='#Conic_Weight'>Weight</a> is less than one, <a href='#Conic'>Conic</a> follows an elliptical arc.
If <a href='#Conic_Weight'>Weight</a> is exactly one, then <a href='#Conic'>Conic</a> is identical to <a href='#Quad'>Quad</a>; <a href='#Conic'>Conic</a> follows a
parabolic arc. If <a href='#Conic_Weight'>Weight</a> is greater than one, <a href='#Conic'>Conic</a> follows a hyperbolic
arc. If <a href='#Conic_Weight'>Weight</a> is infinity, <a href='#Conic'>Conic</a> is identical to two line segments, connecting
start <a href='SkPoint_Reference#Point'>Point</a> to control <a href='SkPoint_Reference#Point'>Point</a>, and control <a href='SkPoint_Reference#Point'>Point</a> to end <a href='SkPoint_Reference#Point'>Point</a>.
### Example
<div><fiddle-embed name="2aadded3d20dfef34d1c8abe28c7bc8d"><div>When <a href='#Conic_Weight'>Conic Weight</a> is one, <a href='#Quad'>Quad</a> is added to path; the two are identical.
</div>
#### Example Output
~~~~
move {0, 0},
quad {0, 0}, {20, 30}, {50, 60},
done
~~~~
</fiddle-embed></div>
If weight is less than one, <a href='#Conic'>Conic</a> is an elliptical segment.
### Example
<div><fiddle-embed name="e88f554efacfa9f75f270fb1c0add5b4"><div>A 90 degree circular arc has the weight1 / sqrt(2).
</div>
#### Example Output
~~~~
move {0, 0},
conic {0, 0}, {20, 0}, {20, 20}, weight = 0.707107
done
~~~~
</fiddle-embed></div>
If weight is greater than one, <a href='#Conic'>Conic</a> is a hyperbolic segment. As weight gets large,
a hyperbolic segment can be approximated by straight lines connecting the
control <a href='SkPoint_Reference#Point'>Point</a> with the end <a href='SkPoint_Reference#Point'>Points</a>.
### Example

## <a name='Arc'>Arc</a>
<a href='#Arc'>Arc</a> can be constructed in a number of ways. <a href='#Arc'>Arc</a> may be described by part of <a href='undocumented#Oval'>Oval</a> and angles,
by start point and end point, and by radius and tangent lines. Each construction has advantages,
and some constructions correspond to <a href='#Arc'>Arc</a> drawing in graphics standards.
All <a href='#Arc'>Arc</a> draws are implemented by one or more <a href='#Conic'>Conic</a> draws. When <a href='#Conic_Weight'>Conic Weight</a> is less than one,
<a href='#Conic'>Conic</a> describes an <a href='#Arc'>Arc</a> of some <a href='undocumented#Oval'>Oval</a> or <a href='undocumented#Circle'>Circle</a>.
<a href='#SkPath_arcTo'>arcTo(const SkRect& oval, SkScalar startAngle, SkScalar sweepAngle, bool forceMoveTo)</a>
describes <a href='#Arc'>Arc</a> as a piece of <a href='undocumented#Oval'>Oval</a>, beginning at start angle, sweeping clockwise or counterclockwise,
which may continue <a href='#Contour'>Contour</a> or start a new one. This construction is similar to <a href='undocumented#PostScript'>PostScript</a> and
<a href='undocumented#HTML_Canvas'>HTML Canvas</a> arcs. Variation <a href='#SkPath_addArc'>addArc</a> always starts new <a href='#Contour'>Contour</a>. Canvas::drawArc draws without
requiring <a href='#Path'>Path</a>.
<a href='#SkPath_arcTo_2'>arcTo(SkScalar x1, SkScalar y1, SkScalar x2, SkScalar y2, SkScalar radius)</a>
describes <a href='#Arc'>Arc</a> as tangent to the line (x0, y0), (x1, y1) and tangent to the line (x1, y1), (x2, y2)
where (x0, y0) is the last <a href='SkPoint_Reference#Point'>Point</a> added to <a href='#Path'>Path</a>. This construction is similar to <a href='undocumented#PostScript'>PostScript</a> and
<a href='undocumented#HTML_Canvas'>HTML Canvas</a> arcs.
<a href='#SkPath_arcTo_4'>arcTo(SkScalar rx, SkScalar ry, SkScalar xAxisRotate, ArcSize largeArc, Direction sweep,
SkScalar x, SkScalar y)</a>
describes <a href='#Arc'>Arc</a> as part of <a href='undocumented#Oval'>Oval</a> with radii (rx, ry), beginning at
last <a href='SkPoint_Reference#Point'>Point</a> added to <a href='#Path'>Path</a> and ending at (x, y). More than one <a href='#Arc'>Arc</a> satisfies this criteria,
so additional values choose a single solution. This construction is similar to <a href='undocumented#SVG'>SVG</a> arcs.
<a href='#SkPath_conicTo'>conicTo</a> describes <a href='#Arc'>Arc</a> of less than 180 degrees as a pair of tangent lines and <a href='#Conic_Weight'>Conic Weight</a>.
<a href='#SkPath_conicTo'>conicTo</a> can represent any <a href='#Arc'>Arc</a> with a sweep less than 180 degrees at any rotation. All <a href='#SkPath_arcTo'>arcTo</a>
constructions are converted to <a href='#Conic'>Conic</a> data when added to <a href='#Path'>Path</a>.

### Example
<div><fiddle-embed name="5acc77eba0cb4d00bbf3a8f4db0c0aee"><div>1 describes an arc from an oval, a starting angle, and a sweep angle.
2 is similar to 1, but does not require building a path to draw.
3 is similar to 1, but always begins new <a href='#Contour'>Contour</a>.
4 describes an arc from a pair of tangent lines and a radius.
5 describes an arc from <a href='undocumented#Oval'>Oval</a> center, arc start <a href='SkPoint_Reference#Point'>Point</a> and arc end <a href='SkPoint_Reference#Point'>Point</a>.
6 describes an arc from a pair of tangent lines and a <a href='#Conic_Weight'>Conic Weight</a>.

</pre>
Approximates <a href='#Conic'>Conic</a> with <a href='#Quad'>Quad</a> array. <a href='#Conic'>Conic</a> is constructed from start <a href='SkPoint_Reference#Point'>Point</a> <a href='#SkPath_ConvertConicToQuads_p0'>p0</a>,

<a href='#Quad'>Quad</a> array is stored in <a href='#SkPath_ConvertConicToQuads_pts'>pts</a>; this storage is supplied by caller.
Maximum <a href='#Quad'>Quad</a> count is 2 to the <a href='#SkPath_ConvertConicToQuads_pow2'>pow2</a>.
Every third point in array shares last <a href='SkPoint_Reference#Point'>Point</a> of previous <a href='#Quad'>Quad</a> and first <a href='SkPoint_Reference#Point'>Point</a> of
next <a href='#Quad'>Quad</a>. Maximum <a href='#SkPath_ConvertConicToQuads_pts'>pts</a> storage size is given by:
(1 + 2 * (1 << <a href='#SkPath_ConvertConicToQuads_pow2'>pow2</a>)) * sizeof(SkPoint).
Returns <a href='#Quad'>Quad</a> count used the approximation, which may be smaller
than the number requested.
<a href='#Conic_Weight'>Conic Weight</a> determines the amount of influence <a href='#Conic'>Conic</a> control point has on the curve.
<a href='#SkPath_ConvertConicToQuads_w'>w</a> less than one represents an elliptical section. <a href='#SkPath_ConvertConicToQuads_w'>w</a> greater than one represents
a hyperbolic section. <a href='#SkPath_ConvertConicToQuads_w'>w</a> equal to one represents a parabolic section.
Two <a href='#Quad'>Quad</a> curves are sufficient to approximate an elliptical <a href='#Conic'>Conic</a> with a sweep
of up to 90 degrees; in this case, set <a href='#SkPath_ConvertConicToQuads_pow2'>pow2</a> to one.
