The Imagick::inverseFourierTransformImage() function is an inbuilt function in PHP which is used to implements the inverse discrete Fourier transform (DFT) of the image either as a magnitude / phase or real / imaginary image pair.
Syntax:
bool Imagick::inverseFourierTransformImage( imagickObject $imagick, float $complement )
Parameters: This function accepts two parameters as mentioned above and described below:
- $imagick: It specifies the second image to combine with this one to form either the magnitude / phase or real / imaginary image pair.
- $complement: It contains a boolean which if true, combine as magnitude / phase pair otherwise a real / imaginary image pair.
Return Value: This function returns TRUE on success.
Exceptions: This function throws ImagickException on error.
Below given programs illustrate the Imagick::inverseFourierTransformImage() function in PHP:
Program 1:
<?php   // Create a new Imagick object $imagick1 = new Imagick(   $imagick2 = new Imagick(   $imagick1->inverseFourierTransformImage($imagick2, true);   // Display the image header("Content-Type: image/png"); echo $imagick1->getImageBlob(); ?> |
Output:
Program 2:
<?php   // Create a new Imagick object $imagick1 = new Imagick(   $imagick2 = new Imagick(   $imagick1->inverseFourierTransformImage($imagick2, false);   // Display the image header("Content-Type: image/png"); echo $imagick1->getImageBlob(); ?> |
Output:
