- * jsBezier
- *
- * Copyright (c) 2010 - 2017 jsPlumb (hello@jsplumbtoolkit.com)
- *
- * licensed under the MIT license.
- *
- * a set of Bezier curve functions that deal with Beziers, used by jsPlumb, and perhaps useful for other people. These functions work with Bezier
- * curves of arbitrary degree.
- *
- * - functions are all in the 'jsBezier' namespace.
- *
- * - all input points should be in the format {x:.., y:..}. all output points are in this format too.
- *
- * - all input curves should be in the format [ {x:.., y:..}, {x:.., y:..}, {x:.., y:..}, {x:.., y:..} ]
- *
- * - 'location' as used as an input here refers to a decimal in the range 0-1 inclusive, which indicates a point some proportion along the length
- * of the curve. location as output has the same format and meaning.
- *
- *
- * Function List:
- * --------------
- *
- * distanceFromCurve(point, curve)
- *
- * Calculates the distance that the given point lies from the given Bezier. Note that it is computed relative to the center of the Bezier,
- * so if you have stroked the curve with a wide pen you may wish to take that into account! The distance returned is relative to the values
- * of the curve and the point - it will most likely be pixels.
- *
- * gradientAtPoint(curve, location)
- *
- * Calculates the gradient to the curve at the given location, as a decimal between 0 and 1 inclusive.
- *
- * gradientAtPointAlongCurveFrom (curve, location)
- *
- * Calculates the gradient at the point on the given curve that is 'distance' units from location.
- *
- * nearestPointOnCurve(point, curve)
- *
- * Calculates the nearest point to the given point on the given curve. The return value of this is a JS object literal, containing both the
- *point's coordinates and also the 'location' of the point (see above), for example: { point:{x:551,y:150}, location:0.263365 }.
- *
- * pointOnCurve(curve, location)
- *
- * Calculates the coordinates of the point on the given Bezier curve at the given location.
- *
- * pointAlongCurveFrom(curve, location, distance)
- *
- * Calculates the coordinates of the point on the given curve that is 'distance' units from location. 'distance' should be in the same coordinate
- * space as that used to construct the Bezier curve. For an HTML Canvas usage, for example, distance would be a measure of pixels.
- *
- * locationAlongCurveFrom(curve, location, distance)
- *
- * Calculates the location on the given curve that is 'distance' units from location. 'distance' should be in the same coordinate
- * space as that used to construct the Bezier curve. For an HTML Canvas usage, for example, distance would be a measure of pixels.
- *
- * perpendicularToCurveAt(curve, location, length, distance)
- *
- * Calculates the perpendicular to the given curve at the given location. length is the length of the line you wish for (it will be centered
- * on the point at 'location'). distance is optional, and allows you to specify a point along the path from the given location as the center of
- * the perpendicular returned. The return value of this is an array of two points: [ {x:...,y:...}, {x:...,y:...} ].

- // these connectors are quadratic bezier curves, having a single control point. if both anchors

- // get a straight line. this is also the case if the two anchors are within 'proximityLimit', since
- // it seems to make good aesthetic sense to do that. outside of that, the control point is positioned
- // at 'curviness' pixels away along the normal to the straight line connecting the two anchors.
- //
- // there may be two improvements to this. firstly, we might actually support the notion of avoiding nodes
- // in the UI, or at least making a good effort at doing so. if a connection would pass underneath some node,
- // for example, we might increase the distance the control point is away from the midpoint in a bid to
- // steer it around that node. this will work within limits, but i think those limits would also be the likely
- // limits for, once again, aesthetic good sense in the layout of a chart using these connectors.
- //
- // the second possible change is actually two possible changes: firstly, it is possible we should gradually
- // decrease the 'curviness' as the distance between the anchors decreases; start tailing it off to 0 at some
- // point (which should be configurable). secondly, we might slightly increase the 'curviness' for connectors
