cvs commit: xml-fop/src/java/org/apache/fop/pdf PDFImage.java

  Modified:    src/java/org/apache/fop/pdf PDFImage.java
  Log:
  Image implementation can now indicate if it is DCT encoded (JPEGs).
  Image implementation just outputs its raw content to an OutputStream. Filtering is done by the XObject.
  Image implementation can now indicate which filter set to use (for encoding optimizations like for JPEGs)
