Package org.jpedal

Class 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
