    Add point annotation

    On this page

    Point annotation sticks comments to any point in a document as shown in the picture below:

    You can specify the following properties of the PointAnnotation class:

    • Box defines the annotation position on the page

    To add a point annotation, follow these steps:

    1. Instantiate the Annotator class. Specify the input document path or stream.
    2. Instantiate the PointAnnotation class. Specify the appropriate properties (position, page number, etc).
    3. Call the Add method. Specify the PointAnnotation class.
    4. Call the Save method. Specify the output document path or stream. 

    The following code snippet shows how to add PointAnnotation to the document:

    //Add point annotation to the document from local disk
using (Annotator annotator = new Annotator("input.pdf"))
{
	PointAnnotation point = new PointAnnotation
    {
    	Box = new Rectangle(100, 100, 0, 0),
        CreatedOn = DateTime.Now,
        Message = "This is point annotation",
        PageNumber = 0,
        Replies = new List<Reply>
        {
        	new Reply
            {
            	Comment = "First comment",
                RepliedOn = DateTime.Now
            },
            new Reply
            {
             	Comment = "Second comment",
                RepliedOn = DateTime.Now
            }
        }
    };
    annotator.Add(point);
    annotator.Save("result.pdf"));
}
