Package org.apache.fop.render.pdf

Class ImageRawJPEGAdapter

java.lang.Object
org.apache.fop.render.pdf.AbstractImageAdapter
org.apache.fop.render.pdf.ImageRawJPEGAdapter
All Implemented Interfaces:
PDFImage
public class ImageRawJPEGAdapter extends AbstractImageAdapter
PDFImage implementation for the PDF renderer which handles raw JPEG images.

The JPEG is copied to the XObject's stream as-is but some elements (marker segments) are filtered. For example, an embedded color profile is filtered since it is already added as a PDF object and associated with the XObject. This way, the PDF file size is kept as small as possible.
