3-Heights® PDF Validator - PDF and PDF/A ISO standard compliance validation in C# and Java

The 3-Heights® PDF Validator safeguards the quality of PDF documents and the processes that create them. Documents are checked for conformance with the ISO standards for PDF and PDF/A documents.

PDF is a widespread format; it is therefore important that interoperability is ensured. Documents containing information of relevance to business or intended for archiving, in particular, need to be validated with regard to their correctness and long-term legibility. This is precisely what the Validator does, whether for a single document or an entire batch.

3-Heights™ PDF Validator verifies electronic insurance applications

Insurance applications at ARAG are increasingly being submitted via electronic means. In order to ensure that the insurance applications comply with the required PDF/A standard, the documents have to be validated by means of a gatekeeper-software. The decision was made in favor of the 3-Heights™ PDF Validator.

Areas of use - PDF and PDF/A document validation and quality control

Incoming mail

The Validator checks incoming mail documents for conformance with the minimum requirements, for instance with regard to security, conformance, reproducibility or standardization (PDF/A and PDF). Inadequate documents are rejected.

Archiving

The component also performs the role of an archive gatekeeper, rejecting documents that do not comply with the standard. The Validator can also be used to validate the quality of existing archives and as a quality assurance tool during the conversion of TIFF archives to PDF/A.

Outgoing Mail

The quality of outgoing PDF documents can be checked prior to dispatch. The tool can take guidelines issued by the recipient into account.

Quality management

The Validator can be used in quality management. It is able to monitor conformance with guidelines (CI) across the company or conformity in general, for instance after conversion from another format.

Software manufacturers/OEM

The Validator serves to validate incoming and outgoing documents in applications such as workflow systems and DMS systems as well as – “you sign what you see” – in signature application software.

Check if document meets a specific compliance

Select a PDF/A compliance level and check whether the input PDF document it is compliant or not. In case it is not compliant, get a detailed description of the compliance violations.

C# sample:
// Create the validator
using (PdfValidator validator = new PdfValidator())
{
    // Open input file
    if (!validator.Open(inputPath, "", complianceLevel))
        throw new Exception(String.Format("Input file {0} cannot be opened. " + 
            "{1} (ErrorCode: 0x{2:x}).", inputPath, validator.ErrorMessage, validator.ErrorCode));

    // Validate document
    // If true, the PDF is compliant to the specified compliance level.
    // If false, the validation either aborted or the PDF is not compliant to 
    // the specified compliance level.
    if (!validator.Validate())
    {
        if (validator.ErrorCode == PDFErrorCode.PDF_E_CONFORMANCE)
        {
            Console.WriteLine("Document {0} is not {1} compliant.", inputPath, 
                compliance);

            // Print compliance violations
            PdfError currError = validator.GetFirstError();
            while (currError != null)
            {
                Console.WriteLine("Page: {0}, Object: {1}, {2}", currError.PageNo, 
                    currError.ObjectNo, currError.Message);
                currError = validator.GetNextError();
            }
        }
        else
            throw new Exception(String.Format("Validation of {0} was aborted. {1} " + 
                "(ErrorCode: 0x{2:x}).", inputPath, validator.ErrorMessage, validator.ErrorCode));
    }
    else
        Console.WriteLine("Document {0} is {1} compliant.", inputPath, compliance);

    // Close input file
    validator.Close();
}

Can I trust PDF validation software?

If I use validation software from different manufacturers I sometimes get different results. Why can this happen? Does it mean that I can't trust the software? What can I do about it? I hear these and more questions very often and I can understand the user's concerns...
