EvBezierAttributes Interface

The EvBezierAttributes TS interface defines a blueprint of a JS object that specifies the segments of a Bézier curve item.

Properties

An EvBezierAttributes object has the following properties:

points: EvCoord2D[];

An array of EvCoord2D arrays, an array of 2D coordinates of points that define one or more segments of a Bézier curve item.

Each segment of a Bézier curve is defined by four points specified in the following order:

Starting point
Weight point 1
Weight point 2
Endpoint

A weight point defines how far the segment is pulled in its direction.

If the Bézier curve includes multiple segments, the following rules must be met:

The total number of the points must be divisible by 4.
The coordinates must be the same for:
- The endpoint of a given segment.
- The starting point of the segment following the given segment.
