In this tutorial, we are going to learn how to get the object scale factor of Image using FabricJS. We can create an Image object by creating an instance of fabric.Image. 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 get the object scale factor of Image, we use the getObjectScaling method. Syntax getObjectScaling(): Object Using the getObjectscaling method Example Let’s see a code example to see the logged output when the getObjectScaling method is used. In this case, the default ...

In this tutorial, we are going to learn how to get the image element on which the current instance is based on using FabricJS. We can create an Image object by creating an instance of fabric.Image. 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 get the image element on which the current instance is based on, we use the getElement method. Syntax getElement(): HTMLImageElement Using the getElement method Example In this example, we have used the getElement method to obtain ... Read More

In this tutorial, we are going to learn how to find the real center coordinates of an Image object using FabricJS. We can create an Image object by creating an instance of fabric.Image. 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 real center coordinates of an Image object, we use the getCenterPoint method. Syntax getCenterPoint(): fabric.Point Using getCenterPoint method Example Let’s see a code example to see the logged output when the getCenterPoint method is used. The getCenterPoint ... Read More

In this tutorial, we are going to learn how to find the original size of an Image using FabricJS. We can create an Image object by creating an instance of fabric.Image. 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 original size of an Image, we use the getOriginalSize method. Syntax getOriginalSize(): Object Using the getOriginalSize metho Example In this example, we have used the getOriginalSize method to obtain the width and height values of the image. Here, the ...

In this tutorial, we are going to learn how to find the complexity of an Image instance using FabricJS. We can create an Image object by creating an instance of fabric.Image. 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 complexity of an Image instance, we use the complexity method. This method will return 1 if the current object is directly inherited from a base class and not from a subclass. Syntax complexity(): Number Using the complexity method Example Let’s ... Read More

In this tutorial, we are going to learn how to enable retina scaling for a cloned image using FabricJS. We can create an Image object by creating an instance of fabric.Image. 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 enable retina scaling for a cloned image, we use the enableRetinaScaling property. In this case, the clone image is scaled up by the devicePixelRatio for better rendering on retina screens. There will be no change on the appearance of the image. Syntax cloneAsImage( ... Read More
