Working with PDF Conformance
The Essential PDF currently supports the following PDF conformances:
- PDF/A-1a conformance
- PDF/A-1b conformance
- PDF/X-1a conformance
- PDF/A-2a conformance
- PDF/A-2b conformance
- PDF/A-2u conformance
- PDF/A-3a conformance
- PDF/A-3b conformance
- PDF/A-3u conformance
NOTE
- To know more details about PDF/A standard refer https://en.wikipedia.org/wiki/PDF/A#Description
- To know more details about PDF/X standard refer https://en.wikipedia.org/wiki/PDF/X
NOTE
Essential PDF supports PDF conformances only in Windows Forms, WPF, ASP.NET and ASP.NET MVC platforms.
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);
Font font = new Font("Arial", 20f, FontStyle.Regular);
//Set the font.
PdfFont pdfFont = new PdfTrueTypeFont(font, FontStyle.Regular, 12, false, true);
//Draw the text.
graphics.DrawString("Hello world!", pdfFont, brush, new PointF(20, 20));

An existing PDF document can be converted to PDF/A-1b conformance document, by setting the Conformance value in the PdfLoadedDocument to Pdf_A1B of PdfConformanceLevel. Refer the below code snippet to achieve the same.
//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.

'Save and close the document.
loadedDocument.Save("Output.pdf")
loadedDocument.Close(True)NOTE
- Converting PDF to PDF/X-1a conformance document is not supported.
- CMYK color space images and symbolic fonts are not supported.
