How to maintain the stroke width of a rectangle when scaling with FabricJS?

In this tutorial, we will learn how to maintain the stroke width of a rectangle when scaling using FabricJS. By default, the stroke width increases or decreases based on the object's scale value. However, we can disable this behavior by using thestrokeUniformproperty.

Syntax

new fabric.Rect({ strokeUniform: Boolean }: Object)

Parameters< ;/h2>

• Options (optional)− This parameter is an object that provides additional customizations for the rectangle. definition. Using this parameter, you can change the color, cursor, stroke width, and many other properties related to thestrokeUniformproperty.

Option Key

• strokeUniform< /strong>− This property accepts aBoolean value, allowing us to specify whether the stroke width scales with the object. Its default value is false.

Example 1

Default appearance of stroke width when scaling objects< /p>

Let's look at a code example that describes the default appearance of the stroke width of a rectangular object being scaled. Since we are not using thestrokeUniformproperty, the stroke width will also be affected by the scaling of the object.

Example

Passing strokeUniform property as key

In this In the example, we pass the strokeUniform property as the key and true as the value Therefore, the object's strokes will no longer increase or decrease The scaling of the object will ensure that the stroke always matches the pixel size exactly The input content is: entered for stroke width.
