With LEADTOOLS, loading annotations is done through the AnnCodecs Class

This class supports loading and saving annotation objects from/to XML strings as well as getting information about previously saved annotations data.
This class also supports saving and loading multi-page annotation data where each page contains a full Annotation Container.

Use the AnnCodecs.LoadAll or LoadAllFromString methods to load all the annotation containers from a multi-page XML file or data.

Loading annotations is as simple as the following:

Code:

AnnContainer container = new AnnContainer();
AnnCodecs codecs = new AnnCodecs();
container = codecs.Load("PATH TO XML file", 1);

LEADTOOLS also has support for embedded annotations in formats like TIFF and PDF.

For TIFF it should be sufficient to pass the TIFF into the AnnCodecs.Load() call.

For PDF, when parsing you should set the PDFParsePagesOptions to All or Annotations. Doing so will populate the PdfDocumentPage.Annotations collection if any PDF Annotations are found.

Code:

// Parse everything and for all pages 
PDFParsePagesOptions options = PDFParsePagesOptions.All; 
document.ParsePages(options, 1, -1);
