  append (const Shape2d &shape)

  Appends the contours of shape to this Shape2d .

• void
  appendContour (const Path2d &contour)
• void
  removeContour (size_t i)
• void
  scale (const vec2 &amount, vec2 scaleCenter=vec2())

  Scales the Shape2d by amount.x on X and amount.y on Y around the center scaleCenter .

• void
  transform (const mat3 &matrix)

  Transforms the Shape2d by matrix .

• Shape2d
  transformed (const mat3 &matrix) const

  Returns a copy transformed by matrix .

• Rectf
  calcBoundingBox () const

  Returns the bounding box of the Shape's control points. Note that this is not necessarily the bounding box of the path's shape.

• Rectf
  calcPreciseBoundingBox () const

  Returns the precise bounding box of the Shape's curves. Slower to calculate than calcBoundingBox() .

• float
  calcDistance (const vec2 &pt) const

  Returns the minimum distance from the shape to point pt .

• float
  calcSignedDistance (const vec2 &pt, bool evenOddFill=true) const

  Returns the minimum distance from the Shape2d to point pt . For points inside the Shape2d , the distance is negative. If evenOddFill is true (the default) then Even-Odd fill rule is used, otherwise the Winding fill rule is applied.

• vec2
  calcClosestPoint (const vec2 &pt) const

  Returns the point on the Shape2d that is closest to point pt .

• bool
  contains (const vec2 &pt, bool evenOddFill=true) const

  Returns whether the point pt is contained within the boundaries of the Shape2d . If evenOddFill is true (the default) then Even-Odd fill rule is used, otherwise the Winding fill rule is applied.

• void
  iterate (IT &it)

  Iterates all of the contours and points of a Shape2d .

  Expects a template parameter that implements

  bool operator()( Path2d::SegmentType type, vec2 *points, vec2 *previousPoint ) 
  

  . Functor should return false to cease iteration. A SegmentType of type CLOSE receives &mPoints[0] for its points parameters.
