PdfFormatProvider.Import

[Sindre]

Hi

I am developing an application that should be able to preview a set of documents of different types.
Word, txt, html seems to work fine, but what would really be useful is the ability to preview pdf documents since most of the documents that are going to be previewed in this application is just that.

I noticed in version 2010.3.1129.1040 that a PdfFormatProvider had been included, but the PdfFormatProvider.Import()-method throws a NotSupportedException.

I was just wondering as to when such a method will be supported or if there is another way to preview pdf documents that I have yet to discover?

Regards
Sindre

Hello Sindre,

PDF import is indeed not supported. PDF content, once exported is being layed out in 2D space rather than the flow douments we are using. Thus, implementing it requires an entirely different approach to storing documents. We have plans to implement it, but it has not been scheduled yet. Thus, I cannot provide you with a specific time frame when it will be available.
If you have any other questions, do not hesitate to contact us again.

Hello,

When I try to call  provider.Import(bytes)) I am getting error: "Stack empty"

PdfFormatProvider provider = new PdfFormatProvider();

byte[] bytes = System.IO.File.ReadAllBytes(myPath);
RadFixedDocument document = provider.Import(bytes));

The code is part from your github repo = https://github.com/telerik/document-processing-sdk/blob/master/PdfProcessing/ModifyForms/Program.cs

Hello Ivelin,

Such an error might be caused by something specific in the content of the PDF document. I would like to ask you to share the document you are testing with so we can investigate what is causing the described behavior. 

Since the API you are using is for PdfProcessing and this forum post targets RadRichTextBox for Silverlight, please, open another forum post or support ticket. This will help us keep the forums in a good order and easy to navigate. Thank you in advance for understanding.

Regards,
Tanya
