org.apache.xmlgraphics.util.uri

Other Packages
Package	Description
org.apache.xmlgraphics.io

Apache XML Graphics Commons is a library in which the two XML Graphics subprojects (Apache Batik and Apache FOP) extracted components which are used by both codebases. The goal is to create a clean dependency hierarchy and to make components more visible which can be usable separately (i.e. without Batik and FOP).
