Path2d /

Sets the start point of the path to p . This is the only legal first command, and only legal as the first command.

Sets the start point of the path to ( x , y ). This is the only legal first command, and only legal as the first command.

Closes the path, by drawing a straight line from the first to the last point. This is only legal as the last command.

Reverses the order of the path's points, inverting its winding order.

Returns the point on the curve at parameter t , which lies in the range [0,1]

Returns the point in segment # segment in the range [0, getNumSegments() ) at parameter t in the range [0,1]

Returns the tangent on the curve at parameter t , which lies in the range [0,1]

Returns the point in segment # segment in the range [0, getNumSegments() ) at parameter t in the range [0,1]

Stores into segment the segment # associated with t , and if relativeT is not NULL, the t relative to its segment, in the range [0,1]

if resultTangents aren't null then un-normalized tangents corresponding to resultPositions are calculated.

Translates the Path2d by offset .

Scales the Path2d by amount.x on X and amount.y on Y around the center scaleCenter .

Transforms the Path2d by matrix .

Returns a copy transformed by matrix .

Returns a subsection of the Path2d starting from startT to endT , which lie in the range [0,1] .

Appends a new segment of type segmentType to the Path2d . points must contain an appropriate number of points for the segment type. Note that while the first point for the segment is always required, it will only be used when the Path2d is initially empty.

Returns the bounding box around all control points. As with Shape2d , note this is not necessarily the bounding box of the Path's shape.

Returns the precise bounding box around the curve itself. Slower to calculate than calcBoundingBox() .

Returns whether the point pt is contained within the boundaries of the Path2d . If evenOddFill is true (the default) then Even-Odd fill rule is used, otherwise, the Winding fill rule is applied.

Returns the minimum distance from point pt to the Path2d .

Returns the minimum distance from point pt to segment segment .

Returns the minimum distance from the Shape2d to point pt . For points inside the Shape2d , the distance is negative.

Returns the point on the Path2d closest to point pt .

Returns the point on segment segment that is closest to point pt .

Calculates the length of the Path2d .

Calculates the length of a specific segment in the range [ minT , maxT ], where minT and maxT range from 0 to 1 and are relative to the segment.

Calculates the t value corresponding to relativeTime in the range [0,1) within epsilon of tolerance . For example, relativeTime of 0.5f returns the t-value corresponding to half the length. maxIterations dictates the number of refinement loop iterations allowed, setting an upper bound for worst-case performance. Consider a Path2dCalcCache if using frequently.

Calculates a t-value corresponding to arc length distance . If wrap then the t-value loops inside the 0-1 range as distance exceeds the arc length. Consider a Path2dCalcCache if using frequently.

Solves the time corresponding to segmentRelativeDistance (a measure of arc length). Generally you should use calcNormalizedTime() or calcTimeForDistance() instead.
