public final class ImageConvertor
extends java.lang.Object

This class is a Facade to the different techniques to load Images in Java. Depending on the JDK version of use, different methods may prevail (MediaTracker, ImageIO, JAI, JPEGCodec..etc). This class takes care of the job for you and will pick the most appropriate method. By default, this class will support JPEG and GIF formats. JDK 1.4 and above adds support for PNG along with many other formats supported through the ImageIO plug-ins (TIFF, BMP, JPEG 2000..etc.) See https://jai-imageio.dev.java.net/ for more details about ImageIO plugins.
