Interface URLImage.ImageAdapter

Enclosing class:

URLImage

public static interface URLImage.ImageAdapter

Allows applying resize logic to downloaded images you can use constant resize behaviors defined in this class. This class allows masking and various other effects to be applied to downloaded images.
