Public API and Backward Incompatible Changes

Example of Importing annotations to Presentation documents

class Program
    {
        static void Main(string[] args)
        {
            AnnotationConfig cfg = new AnnotationConfig();
            cfg.StoragePath = "StorageFolder";
            AnnotationImageHandler annotator = new AnnotationImageHandler(cfg);
            if(!Directory.Exists(cfg.StoragePath))
            {
                Directory.CreateDirectory(cfg.StoragePath);
            }
            new License().SetLicense("C:/lic/GroupDocs.Total_from-20160713.lic");
            Stream input = Assembly.GetExecutingAssembly().GetManifestResourceStream("ImportAnnotationsSlides.TestData.testSlideImport.pptx");
            AnnotationInfo[] annotations = annotator.ImportAnnotations(input, DocumentType.Slides);
            Stream clearDocument = Assembly.GetExecutingAssembly().GetManifestResourceStream("ImportAnnotationsSlides.TestData.testSlidesClear.pptx");
            Stream output = annotator.ExportAnnotationsToDocument(clearDocument, annotations.ToList(), DocumentType.Slides);
            using (FileStream fileStream = new FileStream("../../testSlidesExported.pptx", FileMode.Create))
            {
                byte[] buffer = new byte[output.Length];
                output.Seek(0L, SeekOrigin.Begin);
                output.Read(buffer, 0, buffer.Length);
                fileStream.Write(buffer, 0, buffer.Length);
                fileStream.Close();
            }
        }
