Open MS Office documents and convert to PDF in UWP

Saving annotations back to non-PDF formats is not supported. You can instead save the annotated PDFDoc to a PDF file.

PDFViewCtrl has a powerful and seamless conversion system which allows you to stream documents during conversion to PDF. It supports the following file types:

  • Office file conversion: .docx, .pptx, .xlsx, .doc. (with the office conversion Add-On module)
  • Image conversion: .bmp, .jpg, .tif, .png, .gif
  • Image collections (zip archives with any type of image listed above)
  • Markdown: .md (with the office conversion Add-On module)

In this tutorial you will be able to display a non-PDF file in PDFViewCtrl.

Before going forward, please make sure you have finished setting up PDFViewCtrl as described in Implement PDF Viewer Control in UWP app.

The easiest way to display a non-PDF file in PDFViewCtrl is through the pdftron.UWP API.

Directly from an IRandomAccessStream

You must first retrieve a file as a IRAndomAccessStream Interface:

C#

1Windows.Storage.Streams.IRandomAccessStream StreamForConversion;

Then load the IRandomAccessStream Interface into an IFilter Interface:

C#

1pdftron.Filters.IFilter filter = new pdftron.Filters.RandomAccessStreamFilter(StreamForConversion);

Then add the following when you would like to show the document in your PDFViewCtrl:

C#

1pdftron.PDF.DocumentConversion.conversion = pdftron.PDF.Convert.UniversalConversion(filter, null);
2pdftron.PDF.PDFViewCtrl.PDFViewCtrl.OpenUniversalDocument(conversion);
