This post combines the logic from two other annotation conversion posts. The result allows you to convert PDF annotations to P8 annotation strings using LEADTOOLS' AnnObjects as the step between:
Code:

string pdfFile = @"Some file path";
string p8Directory = @"Some folder path";
AnnContainer[] containers = PDFToLEAD(pdfFile);
LEADToP8Directory(containers, p8Directory);
Additional Information:
PDF Annotations to LEADTOOLS' AnnObjects:
Original Post: https://www.leadtools.com/support/forum/posts/m43645-HOW-TO--Convert-a-PDF-Annotation-to-a-LEAD-Annotation#post43645
Note: I have simplified the original code slightly
Code:

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();
}

LEADTOOLS' AnnObjects to P8 Annotation Strings:
Original Post: https://www.leadtools.com/support/forum/posts/t12578-HOW-TO--Convert-LEADTOOLS--AnnObjects-to-P8-Annotation-Strings
Code:

static void LEADToP8Directory(IEnumerable<AnnContainer> containers, string p8Directory)
{
	Directory.CreateDirectory(p8Directory);
	int page = 1;
	foreach (AnnContainer container in containers)
	{
		IBMP8WriteOptions writeOptions = new IBMP8WriteOptions()
		{
			Formatted = true,
			ForMultiPageTiff = false,
			InferForMultiPageTiffFromMetadata = false,
			InferPageNumberFromMetadata = false,
			Mapper = container.Mapper,
			PageNumber = page++
		};
		foreach (AnnObject annObject in container.Children)
		{
			// Provide a default guid
			if (String.IsNullOrEmpty(annObject.Guid))
				annObject.Guid = Guid.NewGuid().ToString();

			File.WriteAllText(
				Path.Combine(p8Directory, $"{annObject.Guid}.xml"),
				AnnCodecs.ConvertToIBMP8(annObject, writeOptions)
			);
		}
	}
}
