The ICEpdf Viewer is a reference implementation (RI) of a standalone PDF viewer application. You can use it as is, or as a starting point for your own custom application.

The application uses the SwingViewBuilder object to create the GUI elements in the viewer application, such as the toolbar and menu system. These GUI elements, including the page view, are controlled by the SwingController object which produces a rich viewer application that can be used as is in most implementations.

The source-code for the ICEpdf Viewer Application is located in the [install_dir]/icepdf/viewer/ directory.

Starting the ICEpdf Viewer Application

1. Ensure that JDK 1.5.0 or higher has been installed.

2. Add the relevant JAR files to the classpath. You need at least the following:

  • icepdf-core.jar
  • icepdf-viewer.jar

To enable ICEpdf Pro and full PDF font support, install the following:

  • icepdf-pro.jar
  • icepdf-pro-intl.jar

To enable exporting to SVG, you also require the following Batik JAR files:

  • batik-awt-util.jar
  • batik-dom.jar
  • batik-svg-dom.jar
  • batik-svggen.jar
  • batik-util.jar
  • batik-xml.jar

For more information, see [Batik Library for SVG Support].

To enable viewing of documents that are encrypted with Acrobat standard security, you also require the following Bouncy Castle JAR file (or the JAR for another appropriate JCE 1.2.1 security provider implementation):

  • bcprov-jdk{version}.jar (where version is the appropriate version of the JAR)

For more information, see Acrobat Standard Security Support.

3. Run "java org.icepdf.core.ri.viewer.Main [option <value>]"

Starting as an Executable JAR

The ri_pdf.jar file is an executable JAR file, so you can also start the Viewer Application with JDK 1.5.0 or greater as follows: "java -jar icepdf-viewer.jar"

Command Line Options

Option Description
-loadfile filename Starts the ICEpdf Viewer and displays the specified local PDF file. Use the following syntax:

-loadfile c:/examplepath/file.pdf
-loadurl url Starts the ICEpdf Viewer and displays the PDF file at the specified URL. Use the following syntax:


To start the ICEpdf Viewer without command line options or Batik support:
"java -classpath icepdf-core.jar; icepdf-viewer.jar org.icepdf.core.ri.viewer.main"

Settings Directory

The ICEpdf Viewer stores its settings in the directory:

where <user_dir> is the platform-specific directory specified by the user.home system property.

Using the ICEpdf Viewer
This section describes how to use the ICEpdf Viewer application to do the following:
• Open PDF files
• Understand the ICEpdf Viewer work area
• Navigate and manipulate the view of a PDF document
• Export, save, and print the contents of a PDF document
• Exit a document and the application

Opening PDF Files
You can open a PDF file from the local file system or from a URL.

To open a local PDF file
1. Launch your ICEpdf application (if it is not already running).
2. Click File > Open > File.
3. In the Open dialog box, select a PDF file and click Open.

To open a PDF from a URL
1. Launch ICEpdf.
2. Select File > Open > URL.
3. In the Open URL dialog box, type the URL of a PDF file in the form and click OK.

To open a PDF using Drag and Drop
You can open a PDF file by dragging it from your file system onto the Viewer application window. You can also drag and drop multiple files at once.
Furthermore, some applications allow you to drag and drop URL text strings. If you drag a URL pointing
to a PDF file onto the Viewer application, that file is opened. The text string must contain an http://
prefix and a .pdf reference.

Note: If a file is password protected and security support has been configured, a password dialog is
displayed. You have three attempts to enter the correct password, after which an error message
is displayed. If the file has other security settings, such as "No Printing", the ICEpdf Viewer
respects those settings.

Opening Multiple PDF Files
The ICEpdf Viewer implements a Single Document Interface (SDI) for viewing PDF files. Multiple PDF
files can be viewed at the same time, each in its own application window. Some MDI functionality has

been included in the Window menu, which allows the user to switch between each open Viewer window,
minimize all Viewer windows, and bring all Viewer windows to the front.
An additional ICEpdf Viewer window is opened automatically when you open another PDF file.

About the ICEpdf Viewer Work Area
The ICEpdf Viewer consists of the following four distinct work areas:
Main toolbar - provides controls and buttons to navigate and work with a PDF file.
Document pane - displays a PDF file.
Utility pane - has a bookmark tab which lets you browse a PDF file using a documents bookmarks and a search tab which enables you to search for text in a file.
View toolbar - allows you to change the way a document's pages are displayed in the document pane.
