When we try to convert PDF files to PDF/A file, the errors occurred as below.
The original file is 'a.pdf'.
#1. The image in PDF file has changed position and broken. See 'a_out1.pdf'.#2. It couldn't save to PDF/A format.
#3. There was NULL POINT EXCEPTION error from some of PDF files.
The source code was much the same between below and your sample(http://www.aspose.com/docs/display/pdfnet/Convert+PDF+File+to+PDF-A).
private void button1_Click(object sender, RoutedEventArgs
e)
{
Aspose.Pdf.License license = new Aspose.Pdf.License();
license.SetLicense(@"c:\batch\Aspose.Pdf.lic");
string sfilename = @"c:\Batch\am.pdf";
string sfilename_out = @"c:\Batch\am_out1.pdf";
Document pdfDocument = new Document(sfilename);
// Convert to PDF/A compliant document
//during conversion process, the validation is also performed
//pdfDocument.Validate(sfilename_out,PdfFormat.PDF_A_1B);
pdfDocument.Convert(@"C:\Batch\log.xml", PdfFormat.PDF_A_1B, ConvertErrorAction.Delete);
//pdfDocument.Convert("log.xml", PdfFormat.PDF_A_1B, ConvertErrorAction.Delete);
// Save output document
pdfDocument.Save(sfilename_out);
{
Aspose.Pdf.License license = new Aspose.Pdf.License();
license.SetLicense(@"c:\batch\Aspose.Pdf.lic");
string sfilename = @"c:\Batch\am.pdf";
string sfilename_out = @"c:\Batch\am_out1.pdf";
Document pdfDocument = new Document(sfilename);
// Convert to PDF/A compliant document
//during conversion process, the validation is also performed
//pdfDocument.Validate(sfilename_out,PdfFormat.PDF_A_1B);
pdfDocument.Convert(@"C:\Batch\log.xml", PdfFormat.PDF_A_1B, ConvertErrorAction.Delete);
//pdfDocument.Convert("log.xml", PdfFormat.PDF_A_1B, ConvertErrorAction.Delete);
// Save output document
pdfDocument.Save(sfilename_out);
Please let us know the solution for these errors.
Thank you.
