Class ImageConverterHelper

java.lang.Object

to.etc.domui.util.images.converters.ImageConverterHelper

public class ImageConverterHelper
extends Object

This handles a converter chain. For every operation in the chain we lookup the appropriate factory, then we execute the conversion. For each next conversion we try to reuse the factory if possible with the output of the previous conversion as base. If this does not work we get another factory.
