Class ImageTypeSpecifiers

java.lang.Object

com.twelvemonkeys.imageio.util.ImageTypeSpecifiers

public final class ImageTypeSpecifiers
extends Object

Factory class for creating ImageTypeSpecifiers. Fixes some subtle bugs in ImageTypeSpecifier's factory methods, but in most cases, this class will delegate to the corresponding methods in ImageTypeSpecifier.
