Strikeout annotation marks text fragment with a strikethrough styling like shown at the picture below.

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

• FontColor – color of annotation text;
• Opacity – allows to set annotation opacity;
• Points – annotation positions set by array of points.

Follow these steps to add Strikeout annotation to document:

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

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

//Add strikeout annotation to the document from local disk
using (Annotator annotator = new Annotator("input.pdf"))
{
	StrikeoutAnnotation strikeout = new StrikeoutAnnotation
    {
    	CreatedOn = DateTime.Now,
        FontColor = 65535,
        BackgroundColor = 16761035,
        Message = "This is strikeout annotation",
        Opacity = 0.7,
        PageNumber = 0,
        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
            }
        }
     };
     annotator.Add(strikeout);
     annotator.Save("result.pdf");
}
