How to set the background colour of text lines with Text using FabricJS?
In this tutorial, we are going to learn how to set the background colour of text lines with 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. Similarly we can also set the background colour of text lines by using the textBackgroundColor property. Syntax new fabric.Text(text: String , { textBackgroundColor ...
Read MoreHow to disable the centered rotation of Rectangle using FabricJS?
In this tutorial, we are going to learn how to disable the centered rotation of Rectangle using FabricJS. Rectangle is one of the various shapes provided by FabricJS. In order to create a rectangle, we will have to create an instance of fabric.Rect class and add it to the canvas. By default, all objects in FabricJS use their center as the point of rotation. However, we can change this behaviour by using the centeredRotation property. Syntax new fabric.Rect({ centeredRotation: Boolean }: Object) Parameters ...
Read MoreHow to set the baseline of subscript with Text using FabricJS?
In this tutorial, we are going to learn how to set the baseline of subscript with 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 use the subscript property where we can specify its baseline value. Syntax new fabric.Text(text: String , { subscript : {"size": Number, "baseline": ...
Read MoreHow to disable the centered scaling of Rectangle using FabricJS?
In this tutorial, we are going to learn how to disable the centered scaling of Rectangle using FabricJS. Rectangle is one of the various shapes provided by FabricJS. In order to create a rectangle, we will have to create an instance of fabric.Rect class and add it to the canvas. 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.Rect({ centeredScaling: Boolean }: Object) Parameters Options (optional) − ...
Read MoreHow to set the baseline of superscript with Text using FabricJS?
In this tutorial, we are going to learn how to set the baseline of superscript with 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 use the superscript property where we can specify its baseline. Syntax new fabric.Text(text: String , { superscript : {"size": Number, "baseline": Number}: ...
Read MoreHow to disable the selectability of a Rectangle using FabricJS?
In this article, we are going to learn how to disable selectability of a Rectangle using FabricJS. Rectangle is one of the various shapes provided by FabricJS. In order to create a rectangle, we will have to create an instance of fabric.Rect class and add it to the canvas. In order to modify an object, we have to select it in FabricJS. However, we can change this behaviour by using the selectable property. Syntax new fabric.Rect({ selectable: Boolean }: Object) Parameters Options (optional) ...
Read MoreHow to scale a Line object to a given height using FabricJS?
In this tutorial, we are going to learn how to scale a Line object to a given height using FabricJS. A Line element is one of the basic elements provided in FabricJS. It is used for creating straight lines. Because line elements are geometrically one-dimensional and do not contain an interior, they are never filled. We can create a line object by creating an instance of fabric.Line, specifying the x and y coordinates of the line and adding it to the canvas. In order to scale a Line object to a given height we use the scaleToHeight method. Syntax ...
Read MoreHow to flip a Rectangle horizontally using FabricJS?
In this tutorial, we are going to learn how we can flip a Rectangle object horizontally using FabricJS. Rectangle is one of the various shapes provided by FabricJS. In order to create a rectangle, we will have to create an instance of fabric.Rect class and add it to the canvas. We can flip a rectangle object horizontally using the flipX property. Syntax new fabric.Rect({ flipX: Boolean }: Object) Parameters Options (optional) − This parameter is an Object which provides additional customizations to our ...
Read MoreHow to set the dash pattern of controlling corners of Text using FabricJS?
In this tutorial, we are going to learn how we can implement the dash pattern of controlling corners of Text using FabricJS. The controlling corners of an object allow us to scale, stretch or change its position. We can customize our controlling corners in many ways such as adding a specific colour to it, changing its size etc. We can also specify a dash pattern for the controlling corners by using the cornerDashArray property. Syntax new fabric.Text(text: String, { cornerDashArray: Array }: Object) Parameters text − This parameter accepts ...
Read MoreHow to scale a Line object to a given width using FabricJS?
In this tutorial, we are going to learn how to scale a Line object to a given width using FabricJS. A Line element is one of the basic elements provided in FabricJS. It is used for creating straight lines. Because line elements are geometrically one-dimensional and do not contain an interior, they are never filled. We can create a line object by creating an instance of fabric.Line, specifying the x and y coordinates of the line and adding it to the canvas. In order to scale a Line object to a given width we use the scaleToWidth method. Syntax ...
