I am looking at a tool to convert XFA/PDF documents into “normal/standard” pdf that can be read in all browers.
Your tool looks OK with the trial version, but i need to be sure that it can convert the full PDF document that attach.

Can you do the test and send me the result?
My email is joseluis.lopes@unipartner.com

Thanks in advance

Hi José luis Lopes,

Thanks for your interested in our API’s.

I have tested the scenario of XFA form to standard PDF file and as per my observations, the resultant file is properly being generated. For your reference, I have also attached the output generated over my end.

In order to remove limitations of trail version, you may consider requesting a 30 days temporary license by following instructions specified over Get a temporary license

[C#]

Document pdfDocument = new Document(@“C:\pdftest\change+project.pdf”);
pdfDocument.Form.Type = FormType.Standard;
pdfDocument.Save(@“C:\pdftest\change+project_Standard.pdf”);

The field “Fundamentação (Máximo de 4000 caracteres)” is not displayed with the correct number of lines.
This is a huge problem

Hi José luis Lopes,


Thanks for contacting support.

Are you getting above stated exception while using earlier shared document or its appearing for some other document ? Please note that during my testing with Aspose.Pdf for .NET 11.7.0, I did not notice any exception during form field type conversion.

If its occurring for some other document, please share the resource file, so that we can try replicating the problem in our environment. We are really sorry for this inconvenience.

I’ve add a Zip-file with 3 Sample Dokuments.

Hi José luis Lopes,


Thanks for sharing the resource files.

I have tested the XFA to Standard form type conversion scenarios and have managed to reproduce following issues.

  • test 08df6e85-13b5-4cda-b17c-4d1ebe24f847.pdf - I did not notice any problem when converting this form to Standard form type. However I have observed many formatting and missing contents issues in resultant file. For the sake of correction, I have logged it as PDFNET-41040 in our issue tracking system.
  • test 63dd0fe8-cbc9-461a-954b-9e71fc80f406.pdf - I have managed to reproduce the NullReferenceException. For the sake of correction, I have logged it as PDFNET-41037 in our issue tracking system.
  • test ccebc5cb-84b9-4d8b-b469-5e3a8be9d9de.pdf - I have managed to reproduce the NullReferenceException. For the sake of correction, I have separately logged it as PDFNET-41038 in our issue tracking system.

We will further look into the details of these problems and will keep you updated on the status of correction. Please be patient and spare us little time. We are sorry for this inconvenience.

The Dokument

08df6e85-13b5-4cda-b17c-4d1ebe24f847.pdf

seems to be converted but there are some Issues more:



1. Convert to PDFA does not work

2. Convert to PdfFormat.v_1_5 works but all Values are lost

3. Save as *.doc works but all Values get lost.



It would be nice to have a Timeline or some more Information about the progress of fixing this Issues / Bugs because i have seen some other threads with Problems Converting Forms so this must be a general problem

As we recently we noticed these problems, so until or unless we have investigated them in details, we may not be able to share the possible time lines regarding their resolution. Also please note that each conversion scenario is dependent upon the structure of input document, so the time taken by API to resolve these issues varies from document to document. Nevertheless, as soon as we have some definite timelines regarding their resolution, we will let you know.

Thankas

HI,


I am also facing the same problem. I tried, but was unable to successfully flatten out the file.

1.
Aspose.Pdf.Document doc = new Document(“C:\InputLiveCyclePDF_2.pdf”);
doc.Flatten();
doc.OptimizeSize = true;
doc.Optimize();
doc.Save(“C:\OutPut-Document.Flatten_2.pdf”);

This code is working if I open the flatten file with Adobe Reader. But If I open the same form in Adobe Pro all the fields are populated and editable

2.
Aspose.Pdf.Facades.Form pdfForm = new Aspose.Pdf.Facades.Form(“C:\InputLiveCyclePDF_2.pdf”, “C:\Outputfile-FlattenAllFields_2.pdf”);
pdfForm.FlattenAllFields();
pdfForm.Save();

This code is working if I open the flatten file with Adobe Pro. But If I open the same form in Adobe adobe reader all the hidden fields are also populated.

3.

Aspose.Pdf.Document doc = new Document(“C:\InputLiveCyclePDF_2.pdf”);
// Set the form fields type as standard AcroForm
doc.Form.Type = FormType.Standard;
doc.Flatten();
doc.OptimizeSize = true;
doc.Optimize();
doc.Save(“C:\ OutPut-Document_Standard.Flatten_2.pdf”);

This code is rendered all the controls irrespective of the radio button selection.

Here with I have attached the sample documents for your reference

Is there any solution to create flatten form that works in both Adobe Reader and Adobe Pro.

We are using Aspose.Pdf_11.7.0

Thank you in Advance
