Fabric.js Polyline strokeDashArray Property
Last Updated :
24 Jan, 2021
In this article, we are going to see how to set the stroke dash pattern of a canvas Polyline using Fabric.js. The Polyline in Fabric.js is movable and can be stretched according to requirement. Further, the Polyline can be customized when it comes to initial stroke color, height, width, fill color, or stroke width.
To make it possible we are going to use a JavaScript library called Fabric.js. After importing the library, we will create a canvas block in the body tag that will contain the Polyline. After this, we will initialize instances of Canvas and Polyline provided by Fabric.js, set the stroke color and stroke dash pattern using the stroke and strokeDashArray property, and render the Polyline on the Canvas as given in the below example.
Syntax:
var polyline = new fabric.Polyline(Points, {
strokeDashArray: Array
});
Parameters: This property accepts a single parameter as mentioned above and described below:
- strokeDashArray: It specifies the stroke dash pattern.
The below example illustrates the top property in Fabric.js:

// Initiate a polyline instance
var polyline = new fabric.Polyline([
{

}, {
x: 250,
y: 50
}, {
x: 250,
y: 180
}, {

y: 180
}, {
x: 150,
y: 50
}, {
x: 200,
y: 10
}], {
stroke: 'green',
strokeWidth: 3,
fill: 'yellow',
strokeDashArray: [10]
});
// Render the polyline in canvas
canvas.add(polyline);
</ script >
</ body >
