The Above answer only provides you way to add Annotations (of Type FreeText etc). Generally you would want to create/Modify Fields. I normally use PdfTextFields, PdfCheckboxes, PdfSignature Field for this purpose. Hope that helps

    PdfMemDocument memDoc;
    PdfFileInputStream fileInputStream(filePath);
    char *srcBuffer = new char[fileInputStream.GetFileLength()];
    size_t srcLen = fileInputStream.GetFileLength();
    fileInputStream.Read(srcBuffer,srcLen);


    PdfOutputDevice outputDevice(filePath);
    outputDevice.Write(srcBuffer,srcLen);
    memDoc.Load(srcBuffer,srcLen);

    PdfTextField txtField  = PdfTextField( pPage,PdfRect(50, 50, 50, 50),&memDoc);
    txtField.SetFieldName(@"SomeUniqueName");

    memDoc.Write(&outputDevice);
    outputDevice.Flush();
