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

string p8Directory = @"Some folder path";
string pdfFile = @"Some file path";
AnnContainer[] containers = P8DirectoryToLEAD(p8Directory);
LEADToPDF(containers, pdfFile);
Additional Information:
P8 Annotation Strings to LEADTOOLS' AnnObjects:
Original Post: https://www.leadtools.com/support/forum/posts/t12577-HOW-TO--Convert-P8-Annotation-Strings-to-LEADTOOLS--AnnObjects

static AnnContainer[] P8DirectoryToLEAD(string p8Directory)
	List<AnnContainer> containers = new List<AnnContainer>();
	AnnRenderingEngine renderingEngine = new AnnWinFormsRenderingEngine();

	foreach (string p8File in Directory.EnumerateFiles(p8Directory, "*.xml", SearchOption.TopDirectoryOnly))
		// Read the file contents
		string p8Annotation = File.ReadAllText(p8File);

		// Determine the page number
		int page = 1;
		string pagePropValue = AnnCodecs.ReadIBMP8PropDescAttr(p8Annotation, AnnCodecs.IBM_PAGENUMBER);
		if (!String.IsNullOrEmpty(pagePropValue) && Int32.TryParse(pagePropValue, out page))
			page = Math.Max(1, page);

		// Get the AnnContainer for that page
		while (containers.Count < page)
			containers.Add(new AnnContainer());
		AnnContainer container = containers[page - 1];

		// Convert to an AnnObject
		IBMP8ReadOptions readOptions = new IBMP8ReadOptions()
			Mapper = container.Mapper,
			RenderingEngine = renderingEngine
		container.Children.Add(AnnCodecs.ConvertFromIBMP8(p8Annotation, readOptions));

	return containers.ToArray();

LEADTOOLS' AnnObjects to PDF Annotations:
Original Post: https://www.leadtools.com/support/forum/posts/t12595-HOW-TO--Convert-LEADTOOLS--AnnObjects-to-PDF-Annotations

static void LEADToPDF(IEnumerable<AnnContainer> containers, string pdfFile)
	// Load the information about the PDF file
	PDFFile file = new PDFFile(pdfFile);

	// Convert all annotations
	List<PDFAnnotation> fileAnnotations = new List<PDFAnnotation>();
	int page = 1;
	foreach (AnnContainer container in containers)
		// Convert the page annotations
		List<PDFAnnotation> pageAnnotations = new List<PDFAnnotation>();
		AnnPDFConvertor.ConvertToPDF(container, pageAnnotations, file.Pages[page - 1].Height);

		// Set the page number
		foreach (PDFAnnotation annotation in pageAnnotations)
			annotation.PageNumber = page;

		// Add to the total list

		// Increment the page count

	// Write the annotations to the file
	file.WriteAnnotations(fileAnnotations, pdfFile);
