## Class DCTFilter

- java.lang.Object
- - org.apache.fop.pdf.PDFFilter
  - - org.apache.fop.pdf.NullFilter
    - - org.apache.fop.pdf.DCTFilter

-     public class DCTFilter
      extends NullFilter

  DCT Filter class. Right now it is just used as a dummy filter flag so we can write JPG images to the PDF. The encode method just returns the data passed to it. In the future an actual JPEG compression should be added to the encode method so other images can be compressed.
