How 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 ...

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 ...

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 MoreSmallest possible length constituting greatest frequency in JavaScript
ProblemWe are required to write a JavaScript function that takes in an array of numbers, arr, as the first and the only argument.Our function is supposed to find the smallest possible length of a (contiguous) subarray of the array arr, that has the same greatest frequency of any element as the whole array.For example, if the input to the function isInputconst arr = [55, 77, 77, 88, 55];Outputconst output = 2;Output ExplanationThe input array has the greatest frequency for any element of 2 because both elements 55 and 77 appear twice.Of the subarrays that have the greatest frequency as the ...
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 ...
Read MoreHow to lock the rotation of a Triangle using FabricJS?
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 ...
Read MoreHow to lock the horizontal skewing of Triangle using FabricJS?
In this tutorial, we are going to learn how to lock the horizontal 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 horizontally. This can be done by using the lockSkewingX property.Syntaxnew fabric.Triangle({ lockSkewingX : 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 ...
