Fabric.js | Triangle backgroundColor Property
Last Updated :
09 Feb, 2021
In this article, we are going to see how to draw a fill colored canvas Triangle using FabricJS. The canvas triangle means the triangle is movable and can be stretched according to requirement. Further, the triangle can be customized when it comes to initial stroke color, height, width, or stroke width.
To make this possible we are going to use a JavaScript library called FabricJS. After importing the library, we will create a canvas block in the body tag which will contain the triangle. After this, we will initialize instances of Canvas and triangle provided by FabricJS and enable the backgroundColor of canvas triangle using backgroundColor property and render the triangle on the Canvas as given below.
Syntax:
fabric.Triangle({
width: number,
height: number,
backgroundColor: 'string'
});
Parameters: This function accepts three parameters as mentioned above and described below:
- width: It specifies the width of triangle.
- height: It specifies the height of triangle.
- backgroundColor: This parameter defines the background color of the triangle.
Example: This example uses FabricJS to enable the backgroundColor of the canvas-like triangle as given below. Try backgroundColor the object after enabling backgroundColor property, it will fill the triangle by defined color.
