    Extracts a region of the image.

    参数

    The width of the crop

    $height

    The height of the crop

    错误/异常

    错误时抛出GmagickException

    A slight note since this is not immediately obvious:
    Just as the C CropImage() function, you can specify all zero parameters to get an "autocrop" effect, meaning it will remove all single-color "edges" of an image.
