Version 9.1.2 Changelog (January 7, 2022)

Version: 9.1.2

Release Date: January 7, 2022


This release of Apryse for Xamarin brings the core PDF functionality and iOS and Android Tools functionality inline with version 9.1.2 of the iOS and Android SDKs. More information can be found on What's New for iOS and What's New for Android .


  • Adds ability to filter only in the annotation list but not the viewer


New features

  • Support for Annotation states (accepted, rejected, approved, not approved) in the annotation replies UI
  • Inserting new pages can now be done from the "Insert" toolbar
  • Support for drag-and-drop of images onto a PDF, which are added as stamps.
  • Imperial measurements are displayed in fractions of an inch rather than decimals.
  • Externally linked files with destination page numbers are now supported.
  • The arrow drawing direction has been reversed to conform with industry norms and Apryse's Android SDK.
  • New reflow UI options to control if scrolling is vertical or horizontal.
  • Ability to exclude specific annotation types from being removed by the PTEraser tool.
  • The PTSmartPen tool can now be enabled and disabled with the new PTToolManager instance property SmartPenEnabled.
  • Whether to store the newly created signature or persist the setting can now be set in PTSignatureAnnotationOptions.
  • A new document-opening API was added to the PTDocumentController and PTTabbedDocumentViewController classes
    • The optional PTDocumentOptions parameter can be used to specify the file type/extension for files do not have an extension, or for files that have an incorrect extension
  • Events are posted before and after text is copied from a document. Before the text is copied, it is possible to change the text (limit the number of characters, remove sensitive information, etc.).
