MultiPath

Represents a composite path consisting of multiple sub-paths. It is more efficient to use composite paths than individually draw the paths. The interface of the MultiPath mirrors that of the Path, but each moveTo command starts a new sub-path.

options OptionsStore

The configuration of this element.

paths any

A collection of the sub-path.

Constructors

MultiPath (options?: ShapeOptions)

Creates a new MultiPath with the specified options.

Parameters

options? ShapeOptions

The configuration options.

Methods

arc

Draws an arc segment with the specified parameters. Angles increase in a clockwise direction with 0 (zero) pointing "right". Negative values or values greater than 360 are normalized.

Parameters

startAngle number

The start angle of the arc in decimal degrees.

endAngle number

The end angle of the arc in decimal degrees.

rx number

The X radius of the arc.

ry number

The Y radius of the arc.

anticlockwise? boolean

A flag indicating if the arc should be drawn in a clockwise or anticlockwise direction. By default, it is drawn clockwise.

Returns

MultiPath - The current instance to allow chaining.

arcTo

Draws an arc segment to the specified point. The parameters are based on the SVG Arc syntax.

Parameters

end number

The end point of the arc.

rx number

The X radius of the arc.

ry number

The Y radius of the arc.

largeArc boolean

A flag indicating if the arc should be greater or less than 180 degrees.

sweep boolean

A flag indicating if the arc should begin moving at negative or positive angles.

Returns

MultiPath - The current instance to allow chaining.

bbox

Returns the bounding box of the element with applied transformations.

Returns

Rect - The bounding box of the element with transformations applied.

clip

Gets the clipping path for this element.

Returns

Path - The clipping path for this element.

clip

Sets the clipping path for this element. The Path instance will be monitored for changes. Can be replaced by calling the clip method.

The following example demonstrates how to set a clipping path on a Circle.

import { Circle, Surface, Path, geometry } from '@progress/kendo-drawing';
const { transform, Circle: GeomCircle } = geometry;

export function drawScene(surface) {
  // Create the circle geometry and shape
    const geometry = new GeomCircle([ 100, 100 ], 80);
    const circle = new Circle(geometry, {
        stroke: { color: "red", width: 1 }
    });

  // Create a clipping path
    const clipPath = new Path();
    clipPath.moveTo(0, 0).lineTo(100, 100).lineTo(100, 0).close();

  // Clip the circle
    circle.clip(clipPath);

  // Render the group on the surface
    surface.draw(circle);
}

The following example demonstrates how to clear a clipping path.

import { Circle, Surface, Path, geometry } from '@progress/kendo-drawing';
const { transform, Circle: GeomCircle } = geometry;

export function drawScene(surface) {
  // Create the circle geometry and shape
    const geometry = new GeomCircle([ 100, 100 ], 80);
    const circle = new Circle(geometry, {
        stroke: { color: "red", width: 1 }
    });

  // Create a clipping path
    const clipPath = new Path();
    clipPath.moveTo(0, 0).lineTo(100, 100).lineTo(100, 0).close();

  // Clip the circle
    circle.clip(clipPath);

  // Render the group on the surface
    surface.draw(circle);

    setTimeout(() => {
        circle.clip(null);
    }, 2000);
}

Parameters

clip Path

The element clipping path.

clippedBBox

Returns the bounding box of the element with clipping and transformations applied. This is the rectangle that will fit around the actual rendered element.

Returns

Rect - The bounding box of the element with clipping and transformations applied.

close

Closes the current sub-path by linking its current end point with its start point.

Returns

MultiPath - The current instance to allow chaining.

containsPoint

Returns true if the shape contains the specified point.

Parameters

point Point

The point that should be checked.

Returns

boolean value indicating if the shape contains the point.

curveTo

Draws a cubic Bézier curve (with two control points). A quadratic Bézier curve (with one control point) can be plotted by making the control point equal.

Parameters

controlOut Point | number[]

The first control point for the curve.

controlIn Point | number[]

The second control point for the curve.

endPoint Point | number[]

The curve end point.

Returns

MultiPath - The current instance to allow chaining.

fill

Sets the fill of the Shape (see the basic usage example).

Parameters

color string

The fill color to set.

opacity? number

The fill opacity to set.

Returns

MultiPath - The current instance to allow chaining.

lineTo

Draws a straight line to the specified absolute coordinates.

Parameters

x number

The end X coordinate of the line.

y number

The end Y coordinate of the lined.

Returns

MultiPath - The current instance to allow chaining.

lineTo

Draws a straight line to the specified absolute coordinates.

Parameters

point Point

The line end point.

Returns

MultiPath - The current instance to allow chaining.

moveTo

Clears all existing segments and moves the starting point to the specified absolute coordinates.

Parameters

x number

The starting X coordinate.

y number

The starting Y coordinate.

moveTo

Clears all existing segments and moves the starting point to the specified absolute coordinates.

Parameters

opacity

Gets the element opacity.

Returns

number The current element opacity.

opacity

import { Surface, Path } from '@progress/kendo-drawing';

export function drawScene(surface) {
  // Draw a path
    const path = new Path({
        stroke: {

        }
    });
    path.moveTo(25, 75).lineTo(75, 25);

  // Set its opacity to 50%
    path.opacity(0.5);

  // Render the group on the surface
    surface.draw(path);

  // Rotate the path
    path.transform(transform().rotate(-45, [ 50, 50 ]));

  // Render the group on the surface
    surface.draw(path);
}

Parameters
