In this article, we are going to see how to set the absolute position of a canvas circle using FabricJS. It is meaningful only when the object is used as clipPath. The canvas circle is movable and can be stretched according to requirements. Further, the circle 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 FabricJS. After importing the library, we will create a canvas block in the body tag that will contain the circle. After this, we will initialize instances of canvas and circle provided by FabricJS and set the absolute position of a canvas circle using absolutePositioned property.
Syntax:
fabric.Circle({
radius: number,
absolutePositioned: boolean
});
Parameters: This function accepts two parameters as mentioned above and described below.
- radius: It specifies the radius of the circle.
- absolutePositioned: It specifies the absolute position of the object. It contains a boolean value.
Example: This example uses FabricJS to set the absolute position of created simple canvas circle.
