Package org.jpedal

Class PdfDecoderServer

java.lang.Object
org.jpedal.PdfDecoderServer
All Implemented Interfaces:
org.jpedal.PdfDecoderInt
public class PdfDecoderServer extends Object implements org.jpedal.PdfDecoderInt
Provides an object to decode PDF files and provide a rasterizer if required - Normal usage is to create instance and access via public methods. If you require viewing and printing as well, use PdfDecoder/PdfDecoderFX (which also include all the functionality in PdfDecoderServer)

Examples showing usage in org.jpedal.examples
We recommend you access JPedal using only public methods listed in API
