public class ResourceHandler extends java.lang.Object implements org.apache.xmlgraphics.ps.dsc.DSCParserConstants, PSSupportedFlavors
This class is used when two-pass production is used to generate the PostScript file (setting "optimize-resources"). It uses the DSC parser from XML Graphics Commons to go over the temporary file generated by the PSRenderer and adds all used fonts and images as resources to the PostScript file.
