org.apache.xmlgraphics.image.loader.spi.ImageLoaderFactory
This interface is implemented to provide information about an ImageLoader and to create new instances. A separate factory allows implementation to dynamically detect if the underlying libraries are available in the classpath so the caller can skip this implementation if it's not functional.
