Public API and Backward Incompatible Changes

1.  Adding Ellipse annotation.

   // minimal set of parameters
   AnnotationInfo ellipse = new AnnotationInfo();
   ellipse.setBox(new Rectangle(100, 100.0, 50, 50));
   ellipse.setType(AnnotationType.Ellipse);
   

2. GetThumbnail method returns JPEG image stream.
   Assume we are getting pages from document:

   List<PageImage> pages = annotationHandler.getPages(document);
   
   // Then if we want get thumbnail we call GetThumbnail() method of PageImage item:
   for (int i = 0; i < pages.size(); i++) {
       InputStream stream = pages.get(i).getThumbnail();
       // do something with stream 
   }
   
   // Default image size was 300x180. If need specified image size, you can pass method parameters:
   // image thumbnails 100x100
   for (int i = 0; i < pages.size(); i++) {
       InputStream stream = pages.get(i).getThumbnail(100, 100);
       // do something with stream 
   }
   

3. Added ability to set text watermarks angle.
   The same as adding Watermark annotation, but you should additionally set Watermark rotation angle by setting AnnotationInfo.Angle property (in degrees)

   AnnotationInfo annotation = new AnnotationInfo();
   annotation.setType(AnnotationType.Watermark);
   annotation.setAngle(45.0);
