July 2, 2024

Major Changes:

  • Dramatically improved bookmark loading time efficiency by refactoring the bookmark module.
  • Completely remove support for ASM.JS engine and no longer support for older Safari version below 11.

Enhancements:

  • Switched WASM library loading approach from static to dynamic. The dynamically loaded libraries consist of a main module and several side modules. Only the main module is loaded into memory initially. Side modules are loaded only when needed.
  • Enhanced Stamp’s APIs ‘addAnnotationIcon()’ and ‘setDynamicStamp()’, and UI to accept special characters: hyphen (dash), colon, semicolon, slash, and space.
  • Improved the Edit Text and Add Text tool of Advanced Editor to support the global undo/redo functionality and custom fonts.

New Features:

  • Introduced Dynamic XFA form-fill functionality.
  • Enabled PDF Basic 3D model rendering and viewing support.
  • Enabled creating multiple signatures by sharing /v dictionary.
  • Enabled the z-order change for stacking annotations through newly added API ‘PDFPage::changeAnnotOrder()’ and UI options.
  • Added an event ‘activeMultipleAnnotations’ for selecting multiple annotations or form widgets.
  • Added ‘Annot::setCustomAPStream()’ to set the appearance streams of an annotation object.
  • Added a constructor parameter [options.customs.syncTextScaling=false] in PDFViewer to enable TextBox and Callout to scale with container resizing.
  • Added an event ‘FormFieldImported’ to emit a notification once the data importing has been completed.
  • Added ‘setFileSpec()’ and ’getFileSpec()’ to enable programmatically setting launch action.
  • Added ‘PDFViewer::registerMultimediaPlayers()’to enable embedding custom players to play the target format media files.
  • Added APIs to enable programmatically adding and removing layers within a PDF.
    Relevant APIs:
    addLayerNode
    removeLayerNode
    addLayerGraphicObject
    removeLayerGraphicObject

API Changes:

  • Updated ‘PDFDoc.sign()’ with two enhancements: a new parameter ‘signInfo.shareVDictType’ for adding signatures with a single /V dictionary, and support for array objects in ‘signInfo.pageIndex’ and ‘signInfo.rect’ parameters.
  • Updated the’PDFDoc.exportFormToFile()’ to allow for importing/exporting form data from/to a JSON file.
  • Updated the ‘setStateHandlerConfig()’ with a new option ‘enableAnnotationSelectionTool‘ to toggle on or off the annotation selection.

  • Fixed an issue related to the display of custom fonts.
  • Fixed an issue where black ink annotations with the hex color value #000000 were not rendering correctly in documents.
  • Fixed an issue where annotations without an AP stream were not drawing borders correctly.
  • Fixed an issue where adjusting the size of the callout annotation caused the callout’s container to collapse.
  • Fixed an issue where dragging a stamp annotation across pages caused DataEvents.annotationPositionMoved to return incorrect data.
  • Fixed an issue where appending text to the Note comment was not allowed.
  • Fixed an issue where the Note annotation could not be locked.
  • Fixed an issue where setting the border of a Link annotation to 0 was ineffective.
  • Fixed a permission issue where when the comment content is empty, content could not be added.
  • Fixed permission issues where the Image, Video & Audio, and Link annotations could not be edited in PDFs with annotation modification permissions.
  • Fixed an issue where adding a Textbox and keeping the cursor inside the box, then scrolling past pages, would cause the content to be cleared.
  • Fixed an issue where tapAnnotation could not be triggered on mobile devices.
