Class DrawingPoint

An extension of the NutrientViewer.Geometry.Point that can also store an intensity value. This is used for example inside an ink annotation, where the intensity is the pressure that was exerted by the touch device.

Example

Create and update a point

const point = new DrawingPoint({
  x: 20,
  y: 30,
  intensity: 0.3
});
point.intensity; // => 0.3

Param: args

An object used to initialize the Point. If x or y is omitted, 0 will be used instead. If intensity is omitted, 0.5 will be used (the neutral intensity value).

Default

{ x: 0, y: 0, intensity: 0.5 }

constructor

new DrawingPoint(
    options?: {
        intensity?: number;

): NutrientViewer.Geometry.DrawingPoint
Parameters
- Optionaloptions: { intensity?: number; x?: number; y?: number; [k: string]: unknown }
Returns NutrientViewer.Geometry.DrawingPoint
Overrides Point.constructor

Properties

intensity

intensity: number

The intensity is used to describe the pressure of a point inside an ink annotation. It is capped between 0 and 1 inclusive.

If the touch input does not allow to measure the pressure, a value of 0.5 should be used.

Default

0.5

x

x: number

The x coordinate of the point.

Default

y

y: number

The y coordinate of the point.
