In this tutorial, we are going to learn how we can maintain the stroke width of Triangle while scaling using FabricJS. By default, the stroke width increases or decreases with respect to the object's scale values. However, we can disable this behaviour by using the strokeUniform property.Syntaxnew fabric.Triangle({ strokeUniform: Boolean }: Object)ParametersOptions (optional) − This parameter is an Object which provides additional customizations to our triangle. Using this parameter, properties such as colour, cursor, stroke width, and a lot of other properties can be changed related to the object of which strokeUniform is a property.Options KeysstrokeUniform − This property accepts a ...

In this article, we are going to create a canvas using FabricJS but before that let us understand what a canvas is. For drawing graphics on a webpage, we have a web API called Canvas API. This API is good for drawing basic shapes but adding interaction to it or drawing complex shapes becomes very difficult. Thus FabricJS comes into the picture which is a library built on top of the Canvas API. To use FabricJS, the first thing that needs to be done is to create a FabricJS Canvas.Syntaxnew fabric.Canvas(element: HTMLElement|String, options: Object)Parameterselement − This parameter is the ...
