Public API and Backward Incompatible Changes

From this time Annotation Models overload the standard Equals method and also implement the IEquatable interface with the type of the class from which this method is called.

Example how to use it:

using (Annotator annotator = new Annotator("annotated_file.pdf"))
	var annotations = annotator.Get();
	ImageAnnotation imageAnnotation = new ImageAnnotation
		Box = new Rectangle(100, 100, 100, 100),
		Opacity = 0.7,
		PageNumber = 0,
		ImagePath = "",
		Angle = 100
	foreach (var annotation in annotations)
		if (imageAnnotation.Equals(annotation))
			// Do some stuff here...
