Is there a way to remove an annotation by loading an already created pdf?

Hello,

You can remove all the annotations in a PDF by setting the PageAnnotations merge option to false. Here is a code sample:

     MergeOptions options = new MergeOptions();
     options.PageAnnotations = false;
     MergeDocument document = new MergeDocument(@"Input PDF file path", options);
     document.Draw(@"Output PDF file path");

Thanks,

I want to remove only certain annotation.
If it is possible, please let me know what to do.
It is not working.

public void AddRectangle()
{
                       MergeDocument doc = new MergeDocument("D:\\TestData\\test.pdf");
                        
                        Rectangle rectangle = new Rectangle(100, 100, 50, 50);
                        rectangle.BorderStyle = LineStyle.Solid;
                        rectangle.CornerRadius = 5;
                        rectangle.FillColor = RgbColor.Yellow;
                        rectangle.ID = "Exhibit 1 Rectangle";

                        TextArea textArea = new TextArea("Exhibits 1", 100, 100, 50, 50);
                        textArea.ID = "Exhibit 1 Rectangle";

                        doc.Pages[0].Elements.Add(rectangle);
                        doc.Pages[0].Elements.Add(textArea);
                        doc.Draw("D:\\TestData\\test2.pdf");
}

public void RemoveRectangle()
{
                       MergeOptions options = new MergeOptions();
                        options.PageAnnotations = false;
                        MergeDocument document = new MergeDocument("D:\\TestData\\test2.pdf", options);

                        document.Draw("D:\\TestData\\test3.pdf");
}

The rectangle and letters remain.
See what I want below code.

public void RemoveRectangle()
{
                        MergeDocument document = new MergeDocument("D:\\TestData\\test2.pdf");

                       foreach (Page item in document.Pages)
                        {
                                foreach (PageElement element in item.Elements)
                                {
                                    if (element.ID == "Some ID")
                                    {
                                         Remove this item.
                                    }
                                }
                        }

                        document.Draw("D:\\TestData\\test3.pdf");
}

Hello,

Currently we only support removing all annotations, and not a specific one. We're added this as a feature request and may add it as a feature in a future build, but please note that we do not have any exact time line on this.

Thanks,
