How to set the angle of rotation of a Triangle using FabricJS?
In this tutorial, we are going to set the angle of rotation of a Triangle using FabricJS. Triangle is one of the various shapes provided by FabricJS. In order to create a triangle, we will have to create an instance of fabric.Triangle class and add it to the canvas.The angle property in FabricJS defines the angle of 2D rotation of an object. We also have the centeredRotation property that allows us to use the center point of a triangle as the origin of transformation.Syntaxnew fabric.Triangle({ angle: Number, centeredRotation: Boolean }: Object)ParametersOptions (optional) − This parameter is an Object which provides additional ...
Read MoreHow to make the controlling corners of a Triangle transparent using FabricJS?
In this tutorial, we are going to learn how to make the controlling corners of Triangle transparent using FabricJS. Triangle is one of the various shapes provided by FabricJS. In order to create a Triangle, we will have to create an instance of fabric.Triangle class and add it to the canvas. The transparentCorners property allows us to make the controlling corners of Triangle transparent.Syntaxnew fabric.Triangle( { transparentCorners: 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 ...
Read MoreHow to make a Triangle invisible using FabricJS?
In this tutorial, we are going to learn how to make a Triangle invisible using FabricJS. Triangle is one of the various shapes provided by FabricJS. In order to create a triangle, we will have to create an instance of fabric.Triangle class and add it to the canvas.Our triangle object can be customized in various ways like changing its dimensions, adding a background color or by making it visible or invisible. We can do this by using the visible property.Syntaxnew fabric.Triangle( { visible: Boolean }: Object)ParametersOptions (optional) − This parameter is an Object which provides additional customizations to our Triangle. Using ...
Read MoreHow to maintain stroke width of a Triangle while scaling using FabricJS?
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 ...
Read MoreHow to lock the vertical skewing of a Triangle using FabricJS?
In this tutorial, we are going to learn how to lock the vertical skewing of a Triangle using FabricJS. Just as we can specify the position, colour, opacity and dimension of a triangle object in the canvas, we can also specify whether we want to stop skewing an object vertically. This can be done by using the lockSkewingY property.Syntaxnew fabric.Triangle({ lockSkewingY : 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 ...

Just as we can specify the position, colour, opacity and dimension of a triangle object in the canvas, we can also specify whether we want to stop scaling an object vertically. This can be done by using the lockScalingY property.Syntaxnew fabric.Triangle({ lockScalingY : 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 ...
Read MoreHow to create a canvas using FabricJS?
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 ...
Read MoreHow to lock the vertical skewing of Rectangle using FabricJS?
In this tutorial, we are going to learn how to lock the vertical skewing of a Rectangle using FabricJS. Just as we can specify the position, colour, opacity and dimension of a rectangle object in the canvas, we can also specify whether we want to stop skewing an object vertically. This can be done by using the lockSkewingY property.Syntaxnew fabric.Rect({ lockSkewingY : Boolean }: Object)ParametersOptions (optional) − This parameter is an Object which provides additional customizations to our rectangle. Using this parameter, properties such as colour, cursor, stroke width, and a lot of other properties can be changed related to ...
Read MoreHow to lock the vertical movement of Triangle using FabricJS?
In this tutorial, we are going to learn how to lock the vertical movement of a Triangle using FabricJS. Just as we can specify the position, colour, opacity and dimension of a triangle object in the canvas, we can also specify whether we want it to move only in the X-axis. This can be done by using the lockMovementY property.Syntaxnew fabric.Triangle({ lockMovementY: 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 ...

In this tutorial, we are going to learn how to lock the rotation of a Triangle using FabricJS. Just as we can specify the position, colour, opacity and dimension of a triangle object in the canvas, we can also specify whether we want it to rotate or not. This can be done by using the lockRotation property.Syntaxnew fabric.Triangle({ lockRotation : 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 ...
