    Imagick::distortImage — Distorts an image using various distortion methods

    Beschreibung

    publicImagick::distortImage(int$method, array$arguments, bool$bestfit): bool

    Distorts an image using various distortion methods, by mapping color lookups of the source image to a new destination image usually of the same size as the source image, unless 'bestfit' is set to true.

    If 'bestfit' is enabled, and distortion allows it, the destination image is adjusted to ensure the whole source 'image' will just fit within the final destination image, which will be sized and offset accordingly. Also in many cases the virtual offset of the source image will be taken into account in the mapping.

    Diese Funktion ist verfügbar, wenn Imagick gegen die ImageMagick-Version 6.3.6 oder höher kompiliert wurde.

    Beispiel #1 Using Imagick::distortImage():

    Distort an image and display to the browser.

    <?php

    $im = new Imagick();


    $im->newPseudoImage(100, 100, "pattern:checkerboard");


    $im->setImageFormat('png');


    $im->setImageVirtualPixelMethod(Imagick::VIRTUALPIXELMETHOD_TRANSPARENT);


    $im->setImageMatte(true);


    $controlPoints = array( 10, 10,
    10, 5,

    10, $im->getImageHeight() - 20,
    10, $im->getImageHeight() - 5,

    $im->getImageWidth() - 10, 10,
    $im->getImageWidth() - 10, 20,

    $im->getImageWidth() - 10, $im->getImageHeight() - 10,
    $im->getImageWidth() - 10, $im->getImageHeight() - 30);


    $im->distortImage(Imagick::DISTORTION_PERSPECTIVE, $controlPoints, true);


    header("Content-Type: image/png");
    echo     $im;
    ?>
