    Imagick::forwardFourierTransformImage — Implements the discrete Fourier transform (DFT)

    Description

    publicImagick::forwardFourierTransformimage(bool$magnitude): bool

    Implements the discrete Fourier transform (DFT) of the image either as a magnitude / phase or real / imaginary image pair.

    Parameters

    magnitude

    If true, return as magnitude / phase pair otherwise a real / imaginary image pair.

    Return Values

    Returns true on success.

    Examples

    Example #1 Imagick::forwardFourierTransformImage()

    <?php
    //Utility function for forwardTransformImage
    function createMask() {
    $draw = new \ImagickDraw();

    $draw->setStrokeOpacity(0);
    $draw->setStrokeColor('rgb(255, 255, 255)');
    $draw->setFillColor('rgb(255, 255, 255)');

    //Draw a circle on the y-axis, with it's centre
