范例

Example #1 Imagick::flipImage()

<?php
function flipImage($imagePath) {
    $imagick = new \Imagick(realpath($imagePath));
    $imagick->flipImage();
    header("Content-Type: image/jpg");
    echo $imagick->getImageBlob();
}
?>

To avoid the x-axis and y-axis discussion, flipping emulates a mirror at the bottom (or top) of the image.
