Version 2.2.0 Changelog (2016-04-11)

Breaking Changes

  • To allow for more efficient rendering, the way DocumentViewer calls DisplayMode has changed. Those using custom display modes will need to change their code so that instead of directly extending DisplayMode they pass all their custom functions as an object to DisplayMode.setCustomFunctions, which will ensure backward compatibility of their custom layout code. See the horizontal viewer sample for an example.

Potential Breaking Changes

  • When incremental download is in operation, custom XFDF files that are loaded on the documentLoaded event may subsequently be deleted and replaced with annotations from the PDF file. This can be avoided by passing {useDownloader: false} to WebViewer, as is done in the Hide/Show annotations sample.

PDFNetJS Updates

  • Added incremental download support, so large linearized documents can be opened without needing to download the whole file.
  • Added Document.requestPage so incremental download can be used in conjunction with PDFNetJS.
  • Added document locking to PDFNetJS samples.
  • Added support for IE10
  • Added samples for document redaction, including an implementation using the viewer.
  • Added generator support detection for browsers that have present, but incomplete implementations.
  • Improved sample documentation and commenting.
  • Added a workerTransportPromise option to WebViewer.js
