fit -> Scales the image down proportionally so that it fits within the given dimensions. You must provide both a width and a height. The scaled image will not exceed either of these dimensions.
cover -> Scales the image proportionally and crops it if necessary so that the result has exactly the given dimensions. You must provide both a width and a height. Which parts of the image are cropped away is determined automatically. An intelligent algorithm determines the most important areas of your image.
thumb -> A more advanced implementation of cover that also detects cut out images with plain backgrounds. The image is scaled down to the width and height you provide. If an image is detected with a free standing object it will add more background space where necessary or crop the unimportant parts. This feature is new and we’d love to hear your feedback!
