The invertTransform() method is used to return the inverted form of the specified array transform. This function computes the bit-wise Inversion of an array element.
Syntax:
invertTransform(t)
Parameters: This method accepts a parameter as mentioned above and described below:
- t: This parameter holds the specified array transform.
Return Value: This method returns the inverted form of the specified array transform.
Example 1:
Javascript
<!DOCTYPE html> <html> Â
<head> Â Â Â Â <!-- Adding the FabricJS library --> Â Â Â Â <script src= Â Â Â Â </script> </head> Â
<body> Â Â Â Â <script type= "text/javascript" > Â
        // Calling invertTransform() function over         // some array transform         console.log(fabric.util             .invertTransform([1, 2, 3])); Â
        console.log(fabric.util             .invertTransform([1, 2, 3, 4])); Â
        console.log(fabric.util             .invertTransform([1, 2, 3, 4, 5])); Â
        console.log(fabric.util             .invertTransform([1, 2, 3, 4, 5, 6]));     </script> </body> Â
</html> |
Output:
[null,null,null,null,null,null] [-2,1,1.5,-0.5,null,null] [-2,1,1.5,-0.5,null,null] [-2,1,1.5,-0.5,1,-2]
Example 2:
Javascript
<!DOCTYPE html> <html> Â
<head> Â Â Â Â <!-- Adding the FabricJS library --> Â Â Â Â <script src= Â Â Â Â </script> </head> Â
<body> Â Â Â Â <script type= "text/javascript" > Â
        // Specifying some arrays         var array1 = [5, 10, 15, 20];         var array2 = [1, 3, 5, 7, 9, 11]; Â
        // Calling invertTransform() function         // over the above array transform         console.log(fabric.util.invertTransform(array1));         console.log(fabric.util.invertTransform(array2));     </script> </body> Â
</html> |
Output:
[-0.4,0.2,0.3,-0.1,null,null] [-0.875,0.375,0.625,-0.125,1,-2]
