We can create a Polygon object by creating an instance of fabric.Polygon. A polygon object can be characterized by any closed shape consisting of a set of connected straight line segments. Since it is one of the basic elements of FabricJS, we can also easily customize it by applying properties like angle, opacity etc. In order to identify if the given object is of a Polygon instance, we use the isType method. This method checks if the object is of the specified type and returns a true or false value depending on that. Syntax isType(type: String): Boolean Parameters ... Read More

We can create a Polygon object by creating an instance of fabric.Polygon. A polygon object can be characterized by any closed shape consisting of a set of connected straight line segments. Since it is one of the basic elements of FabricJS, we can also easily customize it by applying properties like angle, opacity etc. In order to check if a Polygon object intersects with another object, we use the intersectsWithObject method. This method checks whether the object that is passed to it, intersects with the polygon object. Syntax intersectsWithObject(other: Object, absolute: Boolean, calculate: Boolean ): Boolean Parameters ... Read More

We can create a Polygon object by creating an instance of fabric.Polygon. A polygon object can be characterized by any closed shape consisting of a set of connected straight line segments. Since it is one of the basic elements of FabricJS, we can also easily customize it by applying properties like angle, opacity etc. In order to find the transform matrix which represents current transformations, we use the calcOwnMatrix method. Syntax calcOwnMatrix(): Array Example 1: Using the calcOwnMatrix Method Let’s see a code example of how we can find the transform matrix which represents current transformations of a ... Read More

We can create a Polygon object by creating an instance of fabric.Polygon. A polygon object can be characterized by any closed shape consisting of a set of connected straight line segments. Since it is one of the basic elements of FabricJS, we can also easily customize it by applying properties like angle, opacity etc. In order to convert a polygon object into HTMLCanvasElement we use the toCanvasElement method. It returns the DOM element of type HTMLCanvasElement, an interface which inherits its properties and methods from the HTMLElement interface. We use the getContext method to find a drawing context on ... Read More

We can create a Polygon object by creating an instance of fabric.Polygon. A polygon object can be characterized by any closed shape consisting of a set of connected straight line segments. Since it is one of the basic elements of FabricJS, we can also easily customize it by applying properties like angle, opacity etc. In order to find the current cursor position on the clicked Polygon object, we use the getLocalPointer method. SyntaxgetLocalPointer( e, pointer ): Object Parameters e − This parameter accepts an Event which denotes the event to operate upon. pointer(optional)− This parameter is an ... Read More

We can create a Polygon object by creating an instance of fabric.Polygon. A polygon object can be characterized by any closed shape consisting of a set of connected straight line segments. Since it is one of the basic elements of FabricJS, we can also easily customize it by applying properties like angle, opacity etc. In order to determine whether fill or stroke should be drawn first, we use the paintFirst property. Syntax new fabric.Polygon( points: Array, { paintFirst: String }: Object ) Parameters points − This parameter accepts an Array which denotes the array of points that ... Read More

We can create a Polygon object by creating an instance of fabric.Polygon. A polygon object can be characterized by any closed shape consisting of a set of connected straight-line segments. Since it is one of the basic elements of FabricJS, we can also easily customize it by applying properties like angle, opacity etc. We can check if the cache is dirty and the renderer is required by using the isCacheDirty method. This method checks whether the cache is dirty and thus lets FabricJS know that something in our canvas has changed which requires re-rendering. SyntaxisCacheDirty( skipCanvas: Boolean ) ...

We can create a Polygon object by creating an instance of fabric.Polygon. A polygon object can be characterized by any closed shape consisting of a set of connected straight line segments. Since it is one of the basic elements of FabricJS, we can also easily customize it by applying properties like angle, opacity etc. We use the isContainedWithinObject to find whether a polygon object is fully contained within the area of another object. It can be used to test whether an object is fully contained within the area of another object. Syntax isContainedWithinObject(other: Object, absolute: Boolean, calculate: Boolean ... Read More
