范例

Example #1 Imagick::affineTransformImage()

<?php
function affineTransformImage($imagePath) {
    $imagick = new \Imagick(realpath($imagePath));
    $draw = new \ImagickDraw();
    $angle = 40 ;
    $affineRotate = array(
        "sx" => cos($angle), "sy" => cos($angle), 
        "rx" => sin($angle), "ry" => -sin($angle), 
        "tx" => 0, "ty" => 0,
    );
    $draw->affine($affineRotate);
    $imagick->affineTransformImage($draw);
    header("Content-Type: image/jpg");
    echo $imagick->getImageBlob();
}
?>

This method has not been properly implemented it seems - it has no effect whatsoever on the image.
