Comparing annotations using the equals method

You have the ability to compare annotations using the Equals method or the already implemented IEquatable interface.

Here is the example of the code:

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 = "www.google.com.ua/images/branding/googlelogo/2x/googlelogo_color_92x30dp.png",
		Angle = 100
	};
	foreach (var annotation in annotations)
	{
		if (imageAnnotation.Equals(annotation))
		{
			// Do some stuff here...
		}
	}
}
