HOW TO: Convert PDF Annotations to P8 Annotation Strings

string pdfFile = @"Some file path";
string p8Directory = @"Some folder path";
AnnContainer[] containers = PDFToLEAD(pdfFile);
LEADToP8Directory(containers, p8Directory);

static AnnContainer[] PDFToLEAD(string pdfFile)
{
	List<AnnContainer> containers = new List<AnnContainer>();

	using (RasterCodecs codecs = new RasterCodecs())
	using (PDFDocument pdfDoc = new PDFDocument(pdfFile))
	{
		// Parses the annotations
		pdfDoc.ParsePages(PDFParsePagesOptions.Annotations, 1, -1);

		// Convert all annotations
		foreach (PDFDocumentPage page in pdfDoc.Pages)
		{
			// Configure the page number for the container
			AnnContainer container = new AnnContainer()
			{
				PageNumber = page.PageNumber
			};

			// Configure the DPI of the container
			using (CodecsImageInfo info = codecs.GetInformation(pdfFile, false, page.PageNumber))
				container.Mapper.MapResolutions(
					container.Mapper.DeviceDpiX, container.Mapper.DeviceDpiY,
					info.XResolution, info.YResolution
				);

			// Convert the page annotations
			AnnPDFConvertor.ConvertFromPDF(
				page.Annotations, container,
				new LeadSizeD(page.Width, page.Height)
			);

			// Add to the total list
			containers.Add(container);
		}
	}

	return containers.ToArray();
}
