Features Introduced

Working with Folders Contained in OST/PST Formats

GroupDocs.Viewer now also allows you to deal with the folders and the sub-folders in Outlook Data File documents (OST/PST). You can retrieve the list of the folders contained by a document and render the messages from a specific folder or the sub-folder such as Inbox, Sent Items, Deleted, InboxSub_Folder_1 etc. This feature is available for rendering the document into HTML, image, and PDF. For working examples, please visit the following documentation articles:

Ignoring Empty Columns in Excel Documents

Sometimes Excel worksheet contains the empty columns along with the columns populated with data. In this case, if the number of empty columns is considerably huge, the rendering time increases and hence, it affects the performance. For such cases, we have introduced a new feature that ignores the empty columns using CellsOptions.IgnoreEmptyColumns property. For a working example, please visit this documentation article.

Improvements

We have included the following improvements in version 18.12:

  • Ignore empty string when it is passed as path to directory with fonts
  • Improve rendering into HTML for Outlook Data Files with subfolders and empty folders
  • Set exception localization feature as obsolete
  • Prevent rendering frozen and invisible CAD layers by default
