Enhancements

  • [JPED-412] - XXE Security Vulnerabilty Prevention
    Fixes have been added to prevent two potential security vulnerabilities in JPedal. We have removed usage of the Java provided class ScriptEngine from our codebase and changed our usage of DocumentBuilderFactory to prevent XXE (XML External Entity Attack) attacks. We would recommend either updating to the latest version of JPedal or disabling XFA with the following method:
    pdfDecoderInstance.addExternalHandler(false, Options.USE_XFA);  
    

    or

    viewerInstance.getPdfDecoder().addExternalHandler(false, Options.USE_XFA);  
    
  • [JPED-412 / JPED-420] - Postscript shading performance improvements
    Two specific PDF file was slow to render using JPedal. Time consumption in Postscript compiler has been reduced.
  • [JPED-413] - Colorspaces are now cached to improve performance
    A document was taking a long time to render with JPedal. Colorspaces are now cached to improve performance.
  • [JPED-408] – Text extraction improvements
    Several improvements to text extraction have been made. This fixes issues with text being extracted in the wrong order and text being merged incorrectly when text added as single characters.
  • [JPED-404] - Workaround for JRE crash when rendering round capped dash strokes
