DocumentInformation Spire.Pdf

[Ade]

Hi,

Currently evaluating the free version.
We have a simple application which loads a pdf template, populates the form fields with results from a database and then saves it as a new pdf file. I would like to change the document information in the new file to replace what was in the original template. I've followed the example code like this:

newPdf.DocumentInformation.Author = "Test Author";
newPdf.DocumentInformation.Creator = "Test Creator";
newPdf.DocumentInformation.Producer = "Test Prod";
newPdf.DocumentInformation.Subject = "TEST Subject";
newPdf.DocumentInformation.Title = "Test Title";
prior to .SaveToFile.

The form fields are all populated correctly but the document information hasn't changed it still is as per the original pdf.

Is it possible to change document information in existing documents or am I missing some code.
thanks

Hello,

Thanks for your inquiry.
I have tested a document and I can change the document information. Could you please provide us your new pdf file here, or sent it to us ( support@e-iceblue.com) via email ? It would be helpful to investigate this issue.

Hello Betsy,

I sent the file by email.

I had to strip out commercial stuff not relevant to the Document Information query.

In checking this amend file I noticed if I removed all the information so they contained empty strings (no text at all) and then ran my code the document information changed.

If I left the document information text in the Author, Title etc etc and than run my code it didn't make any change. So it appears in my case it is not over writing existing document information text with the new details in my code.

In VS2010 debug mode if I put a break point after newPdf.SaveToFile() and check the newpdf.documentinformation in the Locals window it shows the Author etc having the amended details. When I open the new saved file in it still has the old details.

Hope this makes sense.
thanks
