A not-allowed cursor can be used to indicate that any action that has been requested, will not be carried out. not-allowed is one of the native cursor style available which can be used in the FabricJS canvas too.FabricJS provides various types of cursors like default, all-scroll, crosshair, col-resize, row-resize etc. which are reusing the native cursor underhood. Each of these cursors look slightly different based on operating system.Syntaxnew fabric.Canvas(element: HTMLElement|String, { defaultCursor: String }: Object)Parameterselement − This parameter is the element itself which ...

In this article, we are going to learn how to clone a canvas using FabricJS. We can clone a canvas instance by using the clone() method. Usually, this is useful when we want to send our canvas instance remotely to somewhere else, it is usually a good idea to send the canvas instance clone in JSON form instead of sending the image of the canvas. clone() method helps us create a clone of any canvas instance along with its objects.Syntaxclone( callback: Object, propertiesToInclude: Array)ParametersCallback (optional) − This parameter is a callback function which is invoked with a clone.propertiesToInclude (optional) − ...

In this article, we are going to learn how to customize the viewport of the canvas using FabricJS. Viewport is the area which is visible to user on the canvas. We can customize the viewport by using the viewportTransform property which allows us to control the transformation of the viewportSyntaxnew fabric.Canvas(element: HTMLElement|String, { viewportTransform: Array }: Object)Parameterselement − 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) − This parameter is an Object which provides additional customizations to ... Read More

In this article, we are going to learn how to set a custom key to enable/disable uniform scaling in FabricJS. In FabricJS, an object gets transformed proportionally when dragged from its corners. This is called uniform scaling. However, we can enable/disable this behavior by using the uniScaleKey.Syntaxnew fabric.Canvas(element: HTMLElement|String, { uniScaleKey: String }: Object)Parameterselement − 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) − This parameter is an Object which provides additional customizations to our canvas. Using ... Read More

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.Syntaxnew fabric.Canvas(element: HTMLElement|String, { selectionFullyContained: Boolean }: Object)Parameterselement − 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) − This parameter is an Object which provides additional customizations to our canvas. Using this parameter, properties such as color, cursor, border width, and ... Read More

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.Syntaxnew fabric.Canvas(element: HTMLElement|String, { selectionDashArray: Array }: Object)Parameterselement − 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) − This parameter is an Object which provides additional customizations to our canvas. Using this parameter ... Read More

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.Syntaxnew fabric.Canvas(element: HTMLElement|String, { centeredScaling: Boolean }: Object)Parameterselement − 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) − This parameter is an Object which provides additional customizations to our canvas. Using this parameter ... Read More
