PDF/A-1b conformance
You can create a PDF/A-1b document by specifying the conformance level as Pdf_A1B through PdfConformanceLevel Enum when creating the new PDF document, as shown below.
//Create a new document with PDF/A-1b standard.
PdfDocument document = new PdfDocument(PdfConformanceLevel.Pdf_A1B);
//Add a page.
PdfPage page = document.Pages.Add();
//Create PDF graphics for the page.
PdfGraphics graphics = page.Graphics;
//Create a solid brush.
PdfBrush brush = new PdfSolidBrush(Color.Black);
//Set the font.
Font font = new Font("Arial", 20f, FontStyle.Regular);
PdfFont pdfFont = new PdfTrueTypeFont(font, FontStyle.Regular, 12, false, true);
//Draw the text.
graphics.DrawString("Hello world!", pdfFont, brush, new PointF(20, 20));
//Save and close the document.
document.Save("Output.pdf");
document.Close(true);'Create a new document with PDF/A-1b standard.

PDF to PDF/A conversion
An existing PDF document can be converted to PDF/A conformance document, by setting the Conformance value in the PdfLoadedDocument to Pdf_A1B,Pdf_A2B,Pdf_A3B, and Pdf_A of PdfConformanceLevel. Refer to the following code sample to achieve the same.
NOTE
To convert the existing PDF to PDF/A conformance document in .NET Core, you need to include the Syncfusion.Pdf.Imaging.Portable assembly reference in the .NET Core project.
//Load an existing PDF.
PdfLoadedDocument loadedDocument = new PdfLoadedDocument("Input.pdf");
//Set the conformance for PDF/A-1b conversion.
loadedDocument.Conformance = PdfConformanceLevel.Pdf_A1B;
//Save and close the document.
loadedDocument.Save("Output.pdf");
loadedDocument.Close(true);'Load an existing PDF.
Dim document As New PdfLoadedDocument("Input.pdf")
'Set the conformance for PDF/A-1b conversion.
loadedDocument.Conformance = PdfConformanceLevel.Pdf_A1B
'Save and close the document.
loadedDocument.Save("Output.pdf")
loadedDocument.Close(True)//Load an existing PDF document
FileStream docStream = new FileStream(@"Input.pdf", FileMode.Open, FileAccess.Read);
PdfLoadedDocument loadedDocument = new PdfLoadedDocument(docStream);
//Sample level font event handling
loadedDocument.SubstituteFont += LoadedDocument_SubstituteFont ;
//Convert the loaded document to PDF/A document
loadedDocument.ConvertToPDFA(PdfConformanceLevel.Pdf_A1B);
//Save the document
MemoryStream stream = new MemoryStream();
loadedDocument.Save(stream);
stream.Position = 0;
//Close the document
loadedDocument.Close(true);
//Defining the ContentType for pdf file
string contentType = "application/pdf";
//Define the file name
string fileName = "output.pdf";
//Creates a FileContentResult object by using the file contents, content type, and file name
return File(stream, contentType, fileName);To convert an existing PDF document to the PDFA document in .NET Core, you need to substitute the non-embedded fonts in the input document. Refer to the the following code sample to achieve the same.
static void LoadedDocument_SubstituteFont(object sender, PdfFontEventArgs args)
{
//get the font name
string fontName = args.FontName.Split(',')[0];
//get the font style
PdfFontStyle fontStyle = args.FontStyle;
SKFontStyle sKFontStyle = SKFontStyle.Normal;
if (fontStyle != PdfFontStyle.Regular)
{
if (fontStyle == PdfFontStyle.Bold)
{
sKFontStyle = SKFontStyle.Bold;
}
else if (fontStyle == PdfFontStyle.Italic)
{
sKFontStyle = SKFontStyle.Italic;
}
else if (fontStyle == (PdfFontStyle.Italic | PdfFontStyle.Bold))
{
sKFontStyle = SKFontStyle.BoldItalic;
}
}
SKTypeface typeface = SKTypeface.FromFamilyName(fontName, sKFontStyle);
SKStreamAsset typeFaceStream = typeface.OpenStream();
MemoryStream memoryStream = null;
if (typeFaceStream != null && typeFaceStream.Length > 0)
{
//Create the fontData from the type face stream.
byte[] fontData = new byte[typeFaceStream.Length - 1];
typeFaceStream.Read(fontData, typeFaceStream.Length);
typeFaceStream.Dispose();
//Create the new memory stream from the font data.
memoryStream = new MemoryStream(fontData);
}
//set the font stream to the event args.
args.FontStream = memoryStream;
}You can download a complete working sample from GitHub.
NOTE
- Converting PDF to PDF/X-1a conformance document is not supported.
- CMYK color space images and symbolic fonts are not supported.
- From the .NET Framework 3.5 version, the Essential PDF is compatible with the PDF to PDF/A conversion.
Get PDF Conformance Level
You can find the conformance level of the existing PDF document using the Conformance property in the PdfLoadedDocument class. Refer to the following code sample to get the conformance level of the existing PDF document.
//Load an existing PDF document.
PdfLoadedDocument loadedDocument = new PdfLoadedDocument("Input.pdf");
//Get the conformance level of the loaded document.
PdfConformanceLevel conformance = loadedDocument.Conformance;
//Close the document.
loadedDocument.Close(true);'Load an existing PDF.
Dim document As New PdfLoadedDocument("Input.pdf")
'Get the conformance level of the loaded document.
PdfConformanceLevel conformance = loadedDocument.Conformance;
'Close the document.
loadedDocument.Close(True)//Create the file open picker
var picker = new FileOpenPicker();
picker.FileTypeFilter.Add(".pdf");
//Browse and choose the file
StorageFile file = await picker.PickSingleFileAsync();
//Creates an empty PDF loaded document instance.
PdfLoadedDocument loadedDocument = new PdfLoadedDocument();
//Loads or opens an existing PDF document through Open method of the PdfLoadedDocument class
await loadedDocument.OpenAsync(file);
//Get the conformance level of the loaded document.
PdfConformanceLevel conformance = loadedDocument.Conformance;
//Close the document.
loadedDocument.Close(true);//Load an existing PDF document
FileStream docStream = new FileStream(@"Input.pdf", FileMode.Open, FileAccess.Read);
PdfLoadedDocument loadedDocument = new PdfLoadedDocument(docStream);
//Get the conformance level of the loaded document.
PdfConformanceLevel conformance = loadedDocument.Conformance;
//Close the document.
loadedDocument.Close(true);//Load the file as a stream.
Stream docStream = typeof(App).GetTypeInfo().Assembly.GetManifestResourceStream("Sample.Assets.Sample.pdf");
PdfLoadedDocument loadedDocument = new PdfLoadedDocument(docStream);
//Get the conformance level of the loaded document.
PdfConformanceLevel conformance = loadedDocument.Conformance;
//Close the document.
loadedDocument.Close(true);You can download a complete working sample from GitHub.
Get PDF to PDF/A conversion progress
You can get conversion progress using PdfAConversionProgress event.
The following code sample shows the delegate for handling PDF to PDF/A conversion process
//Load a PDF document
PdfLoadedDocument loadedDocument = new PdfLoadedDocument("input.pdf");
//Set the conformance for PDF/A-1b conversion.
loadedDocument.Conformance = PdfConformanceLevel.Pdf_A1B;
loadedDocument.PdfAConversionProgress += pdfAConversion_TrackProgress;
//Save the document
loadedDocument.Save("Output.pdf");
//Close the document
loadedDocument.Close(true);
//Event handler for Track PDF to PDF/A conversion process
void pdfAConversion_TrackProgress(object sender, PdfAConversionProgressEventArgs arguments)
{
MessageBox.Show(String.Format("PDF to PDF/A conversion Process " + arguments. ProgressValue + " % completed"));
