Add replacement annotation

Replacement annotation replaces original text with other provided text fragment. Please check the picture below to know how replacement annotation may look like. 

There is an ability to specify the next properties for ReplacementAnnotation type:

• FontColor - color of annotation text;
• Opacity - allows to set annotation opacity;
• Points - annotation positions set by array of points;
• TextToReplace - text that will be replaced 
   

Follow these steps to add Replacement annotation to document: 

• Instantiate Annotator object with input document path or stream;
• Instantiate ReplacementAnnotation object with desired properties (position, page number, etc);
• Call Add method and pass ReplacementAnnotation object;
• Call Save method with resultant document path or stream;

The following code demonstrates how to add ReplacementAnnotation to the document:

//Add replacement annotation to the document from local disk
using (Annotator annotator = new Annotator("input.pdf"))
{
	ReplacementAnnotation replacement = new ReplacementAnnotation
    {
    	CreatedOn = DateTime.Now,
        FontColor = 65535,
        Message = "This is replacement annotation",
        Opacity = 0.7,
        PageNumber = 0,
        FontSize = 11,
        Points = new List<Point>
        {
        	new Point(80, 730), new Point(240, 730), new Point(80, 650), new Point(240, 650)
        },
        Replies = new List<Reply>
        {
        	new Reply
            {
            	Comment = "First comment",
                RepliedOn = DateTime.Now
            },
            new Reply
            {
                Comment = "Second comment",
                RepliedOn = DateTime.Now
            }
         },
         TextToReplace = "replaced text"
     };
     annotator.Add(replacement);
     annotator.Save("result.pdf");
}
