Pdf to Pdf/A conversion fails

Hi!

We have problem with certain Pdf's that fails to be converted to Pdf/a.
It takes up a lot of memory (must run in x64) and then we get an exception with "Index was outside the bounds of the array.". The following log is also written:

My code is as follows:

using System;
using System.IO;
using Aspose.Pdf;

namespace Pdf2PdfA
{
static class Program
{
static void Main(string[] args)
{
try
{
new License().SetLicense("Aspose.Total.lic");

using (FileStream fs = new FileStream(args[0], FileMode.Open, FileAccess.Read, FileShare.Read))
using (Document pdfDocument = new Document(fs))
using (FileStream fsLog = new FileStream("PdfConv.log", FileMode.Create, FileAccess.Write, FileShare.None))
{
pdfDocument.Convert(fsLog, PdfFormat.PDF_A_1B, ConvertErrorAction.Delete);
}
}
catch (Exception exception)
{
Console.WriteLine(exception.Message);
}
}
}
}

We are using Aspose.pdf version 11.8.0.0

Hi Cary,

Thanks for your inquiry. I have tested your scenario with shared document using Aspose.Pdf for .NET 11.8.0 and managed to observe the reported exception. For further investigation, I have logged an issue in our issue tracking system as PDFNET-41131 and also linked your request to it. We will keep you updated via this thread regarding the issue status.

We are sorry for the inconvenience caused.

Hi!


Are there any updates regarding this issue?
I just tested the case with more recent releases of Aspose.pdf and the problem still exists.
We have a customer who haven’t been able to use parts of our application due to this error for 6 months and we must soon resolve this issue in some way.
