Version 6.1.0 Changelog (2020-02-06)


  • Added a RubberStampCreateTool. This tool is available in the UI under the misc tool group and can be used to add various kinds of rubber stamp annotations to the document.
  • Added a link button in the popups that can be used to link annotations or text to a url or a page number.
  • Created a React component library with various components that integrate with WebViewer. For example, a FileOrganizer component is included that has built-in drag and drop functionality.
  • Added setCropMode and an ALL_PAGES crop mode to CropCreateTool.
  • Added a cropApplied event to CropCreateTool. The event will be triggered after page(s) is cropped.
  • Added a loadDocument API to DocumentViewer. This API has the same usage as loadAsync, but determines the correct type of PartRetriever to use internally.
  • Added a TWO_CLICKS draw mode for LineCreateTool. This allows you to create a line annotation with two clicks instead of clicking and dragging.
  • Added a disable option to instance.updateElement. When this option is true, HTML elements that have Button in the class name won't be clickable.
  • Added a colorPalette option to instance.updateElement to set the colors in the viewer's color palette.
