In this tutorial, we are going to learn how to get the scaled height of Text using FabricJS. We can display text on canvas by adding an instance of fabric.Text. Not only does it allow us to move, scale and change the dimensions of the text but it also provides additional functionality like text alignment, text decoration, line height which can be obtained by the properties textAlign, underline and lineHeight respectively. We can also find the object’s scaled height by using the getScaledHeight method. Syntax getScaledHeight() Example 1 Using the getScaledHeight method Let’s see a code example to see ... Read More

In this tutorial, we are going to learn how to exclude Text object from being saved while using JSON.stringify() in FabricJS. We can display text on canvas by adding an instance of fabric.Text. Not only does it allow us to move, scale and change the dimensions of the text but we can also add additional functionalities. Serialization is used in order to export canvas contents. In order to achieve this we use toObject() and toJSON() methods. The excludeFromExport property allows us to include or omit the object when being exported. Syntax new fabric.Text(text: String , { excludeFromExport : Boolean }: ... Read More

In this tutorial, we are going to learn how to disable the centered scaling of Text using FabricJS. We can display text on canvas by adding an instance of fabric.Text. Not only does it allow us to move, scale and change the dimensions of the text but it also provides additional functionality like text alignment, text decoration, line height which can be obtained by the properties textAlign, underline and lineHeight respectively. When being scaled via controls, assigning a true value to the centeredScaling property, uses the center as the object's origin of transformation. Syntax new fabric.Text(text: String, { centeredScaling: Boolean ... Read More

If you've been keeping up with the JavaScript world in the last few years, you've probably heard of the concept of a "flux" architecture. In a nutshell, flux is a pattern for managing data flow in applications. It was originally designed for use with React, but it can be used with any other JavaScript framework. There are a few different ways to implement flux, but they all share a few key components− Dispatcher − This is a central object that is responsible for managing all data flow in the application. All updates start with the dispatcher. Stores − These are objects ... Read More

In JavaScript, an object can be "flattened" by creating a shallow copy of it. This is useful for creating a snapshot of an object, but can cause problems if the object is later modified. If you need to unflatten an object, you can use the paths for keys to restore the original structure. Using Paths for Keys When an object is flattened, the keys are concatenated into a single string. You can use this string to unflatten the object by creating an object with the same keys and values. For example, consider the following object.var obj = { ... Read More

In JavaScript, an object can be created by using curly braces {}. This is called an object literal. An object literal can contain properties and methods. What is Flattening? Flattening is the process of reducing an object to a single−depth object. In other words, all the properties and methods of the object are contained within a single−depth object. How to Flatten an Object? There are various ways to flatten an object. Using for...in loop The for...in loop can be used to iterate over the properties of an object. For each property, we can add it to a new object. Below ... Read More
