pdfFileEditor.Concatenate(...) throws ArgumentOutOfRangeException

Aspose.PDF Product Family

Hi Aspose Support,

When I merge 2 pdfs placed on disc I receive following exception:
ArgumentOutOfRangeException
Index was out of range. Must be non-negative and less than the size of the collection.Parameter name: index

Here’s the code snippet:
var filesToMerge = new List() {
@“d:\test\broken1.pdf”,
@“d:\test\broken2.pdf”};

var license = new Aspose.Pdf.License();
license.SetLicense(@“Aspose.Total.lic”);

var outputFile = @“d:\test\output.pdf”;

var pdfFileEditor = new PdfFileEditor()
{
MergeDuplicateLayers = false,
CopyOutlines = true,
CopyLogicalStructure = true,
KeepActions = false,
AllowConcatenateExceptions = true
};

pdfFileEditor.Concatenate(filesToMerge.ToArray(), outputFile);

I attach 2 pdf’s and 2 documents (docx, docm) I used to create pdfs in Word, Aspose. Notice that when you change order of merged file, exception is not thrown (unfortunately we can’t do that).

Best regards,
Bartłomiej Chojnowski

Hi,

We are hearing from our clients that this issue occurs quite often. Is there any way to detect pdf that will cause issues before merging?

Hi,

Our investigation showed that this property (of PdfFileEditor) set to True is the factor:

CopyLogicalStructure = true,

when ‘false’ is used merge is done. Unfortunately we require this property be set to True.
