Problem with Some PCL Files


We have a process that converts PCL files to PDF files. Some PCL files process fine. Other files, (which are viewable in other tools) cause the program to end immediately. The Catch block does not get to run. In the debugger the message appearing before termination is:

Your app has entered a break state, but there is no code to show because all threads were executing external code (typically system or framework code).
System.NullReferenceException: ‘Object reference not set to an instance of an object.’

We are running Aspose.PDF version

Is this a known issue? Is there any advice on:
A. Catching the error
B. Working around the error

Aspose.Pdf.Facades.PdfPageEditor pEdit = new Aspose.Pdf.Facades.PdfPageEditor();
Aspose.Pdf.Facades.PdfConverter pdfConverter = new Aspose.Pdf.Facades.PdfConverter();
Aspose.Pdf.LoadOptions loadopt = new Aspose.Pdf.PclLoadOptions();
foreach (string file in fileWithPathArray)
    Aspose.Pdf.Document doc;
        // Crashes on the following:
        doc = new Aspose.Pdf.Document(file, loadopt);
    catch (System.Exception ex)
        // Never gets this far
        throw ex;



Thank you for contacting support.

Would you please share complete stack trace of exception along with source and generated files as ZIP archives, so that we may try to reproduce and investigate it in our environment.


Sending zip with code, input PCL file, and stack trace. Binaries removed to meet max-size limit.

It may be that the source system is producing PCL files with formatting issues. These problems are ignored by the other conversion package of which we are trying to replace with Aspose.pdf.

(Correcting the PCL generator is not a near-term option, due to the volume of that change.)

I would like the file to be converted if at all possible, but in the least, I need to be able to catch any error (rather than have it crash.) Thanks. (396.1 KB)

I can wait for a resolution or I can begin searching for an alternative means of working with the files. Do you have a general sense of how long it should be for a resolution to be available? One month? Six months? Longer?
