Version Changelog (October 26th, 2020)

  • Version:
  • Release Date: October 26th, 2020
  • Built with Xcode 12.0.1 (12A7300)

Annotation Improvements

  • It is now possible to scroll and zoom using two fingers, making concurrent annotating and viewing a seamless experience.

  • Free-text improvements:

    • There is a new keyboard accessory view that allows convenient access to changing the font face, size and color.
    - When editing a text annotation, its bounding box will automatically grow to accomodate the new text. - Tapping on a selected text annotation will enter edit mode.
  • PencilKit annotations that include only highlight annotations are now multiply-blended with the document (as opposed to alpha-blended), giving them an appearance that more accurately resembles a real-life highlighter. This behavior can be toggled using the pencilHighlightMultiplyBlendModeEnabled property on the PTToolsSettingsManager class.

More Improvements

  • When viewing a PDF in horizontal scrolling mode, the page will be scaled down so that the entire page is visible. This behavior can be controlled via the pageFitsBetweenBars property on the PTDocumentBaseViewController class.
  • This release turns on color management by default, using a new highly accurate CMYK color profile. This will ensure CMYK color space PDFs are displayed with accurate colors, at the cost of very slightly slower rendering. If desired, this can be turned off with PTPDFNet.setColorManagement(e_ptno_cms.rawValue).
  • Numeric and date form fields will now automatically show a numeric or date picking keyboard. Numeric fields restrict input to numeric characters.


  • The PTDocument(View)Controller now defaults to use a pageRefViewMode of e_trn_zoom. The effect of this is that when swiping between pages horizontally, the next page will come in at the current page’s zoom level.

Bug fixes

  • Annotations are again selectable by tapping on them while using an annotation creation tool.
  • PencilKit annotations are functional on iPhones running iOS 14.
  • Multi-stroke annotations are saved on app background, tab switch, and tab close when the user does not finish the annotation.
  • The navigation bar and associated toolbars will no longer be shown in certain circumstances when they should not have been.
  • pageRefViewMode of e_trn_zoom works as expected.
  • A slight pause when creating an annotation has been eliminated.
  • Ellipse annotations are again shown in the annotations list.
  • Editing a PencilKit annotation will show the control bars so that the edit may be completed.
