Version Changelog (January 31st, 2020)

  • Version:
  • Release Date: January 31st, 2020
  • Built with Xcode 11.3.1 (11C504)


  • PDFs can be merged with the PTAddPagesViewController, which allows adding pages to a document from another document, image, or set of blank page templates.

    PDF merging
  • Annotations can now be copied and pasted within the same document as well as across documents. Annotation copy/paste can be accessed from the annotation selection menu or programmatically with the PTAnnotationPasteboard class.

  • Blank pages from templates, such as lined, grid, graph, and music, can be added to a document with the PTPageTemplateViewController.

    Blank page templates
  • The PTDocumentViewController now has an "Export" item in its More-menu that allows exporting a PDF as a copy, a file size optimized copy, or a flattened copy. This item can be controlled with the exportButtonHidden property.

  • A double-tap and drag to zoom gesture (like in Apple/Google Maps) was added. This is in addition to the existing double-tap zoom gesture.

  • Annotations can be flattened into the PDF from the annotation selection menu, making them un-editable.

  • Image stamp annotations can now be created from the device camera or existing image files, in addition to photos in the user's Photo Library.

  • It is now possible to crop image stamp annotations with the new PTImageCropTool.

    Image stamp crop

    The crop feature can be disabled with the PTImageStampAnnotationOptions.isCropEnabled property, accessible from the PTToolManager class's imageStampAnnotationsOptions property.
