AbstractAbstractargReturns the parameter values at which lineSegment intersects this shape.
See also intersectsLineSegment
AbstractatReturns true if and only if the given point is contained within this shape.
epsilon is a small number used to counteract floating point error. Thus, if
point is within epsilon of the inside of this shape, containsPoint may also
return true.
The default implementation relies on signedDistance.
Subclasses may override this method to provide a more efficient implementation.
Returns a bounding box that loosely fits the content of this shape.
The result of this call can be larger than the result of getTightBoundingBox,
but should not be smaller. Thus, a call to getLooseBoundingBox can be significantly
faster than a call to getTightBoundingBox for some shapes.
Abstractgetpoints at which this shape intersects the given lineSegment.
If this is a closed shape, returns points where the given lineSegment intersects
the boundary of this.
AbstractnearestAbstractnormalAbstractsignedComputes the signed distance function for this shape.
AbstractsplitDivides this shape into two separate shapes at parameter value .
Abstracttangent
A 2-dimensional path with parameter interval t∈[0,1].
Note: Avoid extending this class outside of
js-draw--- new abstract methods may be added between minor versions.
