How to set the padding of a Rectangle using FabricJS?
In this tutorial, we are going to learn how to set the padding 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. Just as we can specify the position, colour, opacity and dimension of a rectangle object in the canvas, we can also set the padding of a rectangle object. This can be done by using the padding property. Syntax new fabric.Rect({ padding : Number }: Object) ...
Read MoreHow to get the SVG representation of a Line using FabricJS?
In this article, we are going to learn about how to get the SVG representation of a Line 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 get the SVG representation of a Line object, we use the _toSVG method. Syntax ...
Read MoreHow to resize an object non-uniformly via corner points using FabricJS?
In this article, we are going to learn how to resize an object non-uniformly via corner points using FabricJS. In FabricJS, an object gets transformed proportionally when dragged from the corners. However, we can control this behavior by pressing the uniScaleKey. Syntax new fabric.Canvas(element: HTMLElement|String, { uniScaleKey: String }: Object) Parameters element − This parameter is the element itself which can be derived using Document.getElementById() or the id of the element itself. The FabricJS canvas will be initialized on this element. ...

In this tutorial, we are going to learn about how to identify the type of a Line instance 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 identify the type of a Line instance, we use the isType method. Syntax ...
Read MoreHow to disable uniform scaling in canvas using FabricJS?
In this article, we are going to learn about how to disable uniform scaling in canvas using FabricJS. In FabricJS, an object gets transformed proportionally when dragged from the corners. However, we can disable this behavior by using the uniformScaling property. Syntax new fabric.Canvas(element: HTMLElement|String, { uniformScaling: Boolean }: Object) Parameters element − This parameter is the element itself which can be derived using document.getElementById() or the id of the element itself. The FabricJS canvas will be initialized on this element. options (optional) ...
Read MoreHow to set the size of the controlling corners of Rectangle using FabricJS?
In this tutorial, we are going to learn how to set the size of the controlling corners of a Rectangle 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 change the size by using the cornerSize property. Syntax new fabric.Rect({ cornerSize: Number }: Object) Parameters Options (optional) − This parameter is an Object which provides additional customizations to ...
Read MoreHow to enable centered scaling on a canvas using FabricJS?
In this article, we are going to learn how to enable centered scaling on a canvas using FabricJS. In FabricJS, an object gets transformed proportionally when dragged from the corners. We can use the centeredScaling property to use the center as the origin of transformation. Syntax new fabric.Canvas(element: HTMLElement|String, { centeredScaling: Boolean }: Object) Parameters element − This parameter is the element itself which can be derived using Document.getElementById() or the id of ...
Read MoreHow to add dashes to the border of a selection area on a canvas using FabricJS?
In this article, we are going to learn how to add dashes to the border of a selection area on a canvas using FabricJS. We can achieve this by using the selectionDashArray property. It allows us to make the border of a selection area dashed. Syntax new fabric.Canvas(element: HTMLElement|String, { selectionDashArray: Array }: Object) Parameters element − This parameter is the element itself which can be derived using document.getElementById() or the id of the element itself. The FabricJS canvas will be ...
Read MoreHow to set the style of controlling corners of a Rectangle using FabricJS?
In this tutorial, we are going to learn how to set the style of controlling corners 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. 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 change the style by using ...
Read MoreHow to enable selection of object only when it is fully contained in a selection area in FabricJS?
In this article, we are going to learn how to enable the selection of an object only when it is fully contained in the selection area using FabricJS. We can use the selectionFullyContained property to achieve this. Syntax new fabric.Canvas(element: HTMLElement|String, { selectionFullyContained: Boolean }: Object) Parameters element − This parameter is the element itself which can be derived using Document.getElementById() or the id of the element itself. The FabricJS canvas will ...
