Class ResourceHandler

    java.lang.Object
      org.apache.fop.render.ps.ResourceHandler

All Implemented Interfaces:
  PSSupportedFlavors, org.apache.xmlgraphics.ps.dsc.DSCParserConstants

    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.

Method Detail

### process

    public void process(java.io.InputStream in,
                        java.io.OutputStream out,
                        int pageCount,
                        java.awt.geom.Rectangle2D documentBoundingBox)
                 throws org.apache.xmlgraphics.ps.dsc.DSCException,
                        java.io.IOException

  Rewrites the temporary PostScript file generated by PSRenderer adding all needed resources (fonts and images).

  Parameters:
    `in` - the InputStream for the temporary PostScript file
    `out` - the OutputStream to write the finished file to
    `pageCount` - the number of pages (given here because PSRenderer writes an "(atend)")
    `documentBoundingBox` - the document's bounding box (given here because PSRenderer writes an "(atend)")
  Throws:
    `org.apache.xmlgraphics.ps.dsc.DSCException` - If there's an error in the DSC structure of the PS file
    `java.io.IOException` - In case of an I/O error
