In this tutorial, we are going to learn how to include Text object’s default values in its serialization 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 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 includeDefaultValues property allows us to include or omit the object’s default values when being serialized. Syntax new fabric.Text(text: String , { includeDefaultValues: Boolean }: ... Read More
In this tutorial, we are going to learn how to get the style of current selection 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 style of current selection by using the getSelectionStyles method. Syntax getSelectionStyles(startIndexopt, endIndexopt, completeopt) Parameters startIndexopt − This parameter accepts a ... 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
In this tutorial, we will learn how to get the value of the rel attribute of a link in JavaScript.
