'Usage

Class provides the functionality for verification and conversion of PDF document to PDFA standards. The following code example illustrates how the PDF file can be verified and converted using the instance of this class. Notice, the saving of PDF document should be performed with ImGearPDFDocument.Save method because ImageGear.Formats.ImGearFileFormats.SaveDocument does not support thi functionality.

C#

// Stores PDF document to a file as PDFA standard.
   private void SavePdfDocumentAsPDFA(ImGearPDFDocument document, ImGearPDFPreflightProfile profile, string outputFilePathName)
   {
       // Create object-converter. 
       using (ImGearPDFPreflight preflight = new ImGearPDFPreflight((ImGearPDFDocument)document))
       {
        ImGearPDFPreflightReport report = preflight.VerifyCompliance(profile, 0, -1);
        if (report.Code == ImGearPDFPreflightReportCodes.SUCCESS)
        {
            // PDF document is already compliant to PDFA standard.
            // Nothing is performed.
        }
        else
        {
            if (report.Status == ImGearPDFPreflightStatusCode.Fixable)
            {
                // Create conversion options. We need to be sure the "ig_rgb_profile.icm" color profile
                // is placed in executable file directory of this application.
                ImGearPDFPreflightConvertOptions conversionOptions = new ImGearPDFPreflightConvertOptions(profile, 0, -1);
                // Perform the conversion.
                report = preflight.Convert(conversionOptions);
                if (report.Code == ImGearPDFPreflightReportCodes.SUCCESS)
                {
                    // Store converted document to a file.
                    using (Stream stream = new FileStream(outputFilePathName, FileMode.Create, FileAccess.Write))
                        pdfDocument.Save(stream, ImGearSavingFormats.UNKNOWN, 0, 0, (int)ImGearPDFPageRange.ALL_PAGES, ImGearSavingModes.OVERWRITE);
                }
                else
                    throw new ApplicationException("PDF document cannot be converted to APDF standard.");
            }
            else
                throw new ApplicationException("PDF document cannot be converted to APDF standard.");
        }
    }
}
