Error in PDF output document

I have an Excel workbook that I am outputting to PDF through an ASP.NET application using Aspose.Cells. When I output the workbook in Excel format (before saving to PDF using Aspose.Cells), Excel does not report any errors. However, when I use Cells to save the workbook to PDF, when I open the PDF document, I get an error message on the first page of the PDF that says “An error exists on this page. Acrobat may not display the page correctly. Please contact the person who created the PDF document to correct the problem.” I am somewhat at a loss to diagnose what the cause of the error could be, especially as Excel is not reporting any errors. I have attached a copy of the Excel worksheet for your review.

Hi,

Please try the latest version:
Aspose.Cells for .NET v7.0.3.6
and let us know your feedback.

I still get the same error using version 7.0.3.6.

Hi,


It works absolutely fine with v7.0.3.6. The output PDF file opens fine into Adobe acrobat. I have tested with the following code:
Workbook wb = new Workbook(@“e:\test2\Aspose.Cells+PDF+issue.xlsx”);
wb.Save(“e:\test2\Aspose.Cells+PDF+issue.pdf”);

Please fine attached the output PDF file.


Also, check the document for reference on how you will use response object to save to PDF format in ASP.NET:
http://www.aspose.com/documentation/.net-components/aspose.cells-for-.net/saving-files.html

If you still find the issue, kindly give us sample web application, zip it and post it here to show the issue.

we will check it soon.

Thank you.

Unfortunately I can’t give you the application, as we are using Software Artisans Excel Writer to generate the Excel file and I doubt that you have access to that. Basically, I save the excel file created by Excel Writer to a memory stream using the Excel Writer objects like so (where xlt is a an Excel Writer ExcelTemplate object):

MemoryStream xltStream = new MemoryStream();
xlt.Save(xltStream);

Then I create the Aspose.Cells workbook from the stream after evaluating all of the formulas and then hiding all of the pages except the first one like so:

Workbook wb = new Workbook(xltStream);
wb.CalculateFormula();
for (int i = 1; i < wb.Worksheets.Count; i++)
wb.Worksheets[i].IsVisible = false;
wb.Save(this.Response, “QuantSheet.pdf”, ContentDisposition.Attachment, new PdfSaveOptions());

If instead of sending the Excel stream to Aspose.Cells, I output it to the response object as an attachment, I end up with the Excel file that I attached in my initial post. I am attaching the corrupted PDF file here also for your review.

Hi,

Please save xltStream on disk and attach on this thread. We will look into it and update you asap.

Sure. Here it is.
