mask — Apply an alpha mask to an image

Description

public Intervention\Image\Image mask(mixed $source, [bool $mask_with_alpha])

Apply a given image source as alpha mask to the current image to change current opacity. Mask will be resized to the current image size. By default a greyscale version of the mask is converted to alpha values, but you can set mask_with_alpha to apply the actual alpha channel. Any transparency values of the current image will be maintained.
