public class BrolImageUtils
extends Object

The BrolImageUtils helps to manage images. \n All the available image resources in a Broldev dependency are defined as enumerations to have a low coupling between resources and Java code. These enumerations implement the IBrolImage interface to give some image resources methods. \nThe BrolImageUtils allows to get image resources from any IBrolImage, and uses cache mechanisms to avoid building or loading images on each call. Provided by the broldev.core.model project.
