The Viewer offers several ways to customize the Viewer, from quick integrations with minimal configuration to complete control over the Viewer API. Tabs and basic DRM functions such as printing, text selection, and document download can be quickly hidden using configuration parameters.

It's very simple to reorganize menus, add/remove tabs, and customize the look of the Viewer by allowing the developer to edit markup and css. All Viewer functionality is built on top of the Viewer API, allowing complete control over all Viewer functions.

Configuration Options

The Viewer UI and behavior can be configured when the Viewer is embedded; using JavaScript parameters you can set the following:

• Displaying/Hiding Tabs and DRM functions
• Enabling Content Encryption
• Using a Custom Resource Path
• Localizing the Viewer
• How to use Predefined Search
• Digital Rights Management Configuration

Customizing Markup and Styles

If the Viewer needs to be customized more than configuration options allow, all UI code is open-source and can be modified to change the following:

• Reorganizing Menus
• Creating a Custom Tab
• Changing annotation default values
• Changing the position of the menu bar
• Customizing Styles (css)
