Known Issues

The following section describes the most commonly encountered known issues with this release. For a complete reference of all outstanding issues please refer to the ICEpdf.org JIRA issue tracker.
General

  • Batik libraries version 1.7 for SVG export has a known issue which will cause a null pointer when using the class SVGGraphics2D. Please use Batik version 1.6 or earlier (included in this release bundle), http://xmlgraphics.apache.org/batik/.
  • Depending on which version of the Java Advanced Imaging (JAI) library you are using, the installer program may assume you are installing it on a J2SE JDK installation. If you install the JAI into a J2SE JRE installation, you may need to move the installed files from the /jre subdirectory that the installer creates to the jre directory above. Newer versions of the JAI installer program have fixed this issue.
  • Language support for none English languages is limited to the main Viewer controls and is incomplete for the Utility pane or popup dialogs.
