Saving Aspose.Pdf.Facade.Form.Save(Response.OutputStream) not supported

I am trying to save form output to HttpResponse.OutputStream.

But I am getting “Specified Method is not supported” exception. (Refer to the attachment)

I am in process of converting old Aspose.Pdf.Kit to new Aspose.Pdf release on 4/1/2014.
I was able to save to the Response.OutputStream when I was using PDF Kit but the Aspose.Pdf.Facade.Form method doesn’t allow me to save. Is this a bug? And is there a workaround to this problem?

Thanks,

Here is the code.

public void FillTemplate(string pdfTemplate)
{
string fname = Guid.NewGuid().ToString();
string fname1 = fname + “_1.pdf”;
fname = fname + “.pdf”;

string srcFile = Path.Combine(_context.Request.PhysicalApplicationPath,
string.Format(@"{0}{1}", TempOutput, fname1));
string destFile = Path.Combine(_context.Request.PhysicalApplicationPath,
string.Format(@"{0}{1}", TempOutput, fname));

if (!Directory.Exists(Path.GetDirectoryName(srcFile)))
Directory.CreateDirectory(Path.GetDirectoryName(srcFile));

var pdfFileStamp = new PdfFileStamp(pdfTemplate, srcFile);
AddWLNumberToFooters(pdfFileStamp);

var clientCore = new ClientCore(_queryArg.UserSession.GetConnectionString(), _queryArg.ClientId);
var core = new HILFSCore(_queryArg.UserSession.GetConnectionString(), _queryArg.Login);
var sheet = core.FormGet(clientCore.GetSheetIdForClient());

var srcDoc = new Document(srcFile);
var formEditor = new FormEditor(srcDoc) { Facade = new FormFieldFacade { FontSize = 8F } };
bool shouldLockForm = sheet.DataEntryCompleted.HasValue;
AddSubmitButtons(formEditor, new PdfFileInfo(srcFile).Document.Pages.Count, shouldLockForm);
LockGeneralInfo(formEditor, new HILFSGeneralInfo());
formEditor.Save(destFile);

//formEditor = new Kit.FormEditor(new FileStream(destFile, FileMode.Open), _context.Response.OutputStream)
// { Facade = new Kit.FormFieldFacade { FontSize = 8F } };
var form = new Form(destFile);
FillForm(form, sheet);
if (sheet.DataEntryCompleted != null)
LockForm(form);

//formEditor.Save(destFile);
//formEditor.Save();
form.Save(_context.Response.OutputStream);
}

We have a licence and support for the latest Apose products (Aspose.Total).

I found a workaround.

I am now using Document object to save the PDF instead of Form.

document.Save(_context.Response, “output.pdf”, ContentDisposition.Inline, new PdfSaveOptions());

It works.

Hi,


Thanks for contacting support.

I have tried replicating the issue using code snippet which you have shared above I am unable to execute the code because there are lots of custom variables inside it. However, I have simplified the code and when using latest release of Aspose.Pdf for .NET 9.1.0, I am unable to notice any problem. Can you please share some sample application which can help us in replicating this issue at our end. We are sorry for this inconvenience.

[C#]

string fname = Guid.NewGuid().ToString();<o:p></o:p>

string fname1 = fname + "_1.pdf";

fname = fname + ".pdf";

var pdfFileStamp = new PdfFileStamp();

pdfFileStamp.BindPdf("c:/pdftest/FFATT.pdf");

MemoryStream stream = new MemoryStream();

pdfFileStamp.Save(stream);

var srcDoc = new Document(stream);

var formEditor = new FormEditor(srcDoc) { Facade = new FormFieldFacade { FontSize = 8F } };

MemoryStream stream2 = new MemoryStream();

formEditor.Save(stream2);

var form = new Form(stream2);

MemoryStream finalStream = new MemoryStream();

form.Save(finalStream);

Response.Clear();

Response.ClearHeaders();

Response.ClearContent();

Response.Charset = "UTF-8";

Response.AddHeader("Content-Length", finalStream.Length.ToString());

Response.AddHeader("content-disposition", "inline; filename=" + "CreditApp.pdf");

Response.ContentType = "application/pdf";

Response.BinaryWrite(finalStream.ToArray());

Response.Flush();

Response.End();
