How to: Create a Circle Annotation

The following code snippet creates two annotations - circle and ink:

C#

FileStream fs = File.OpenRead("Demo.pdf");
var options = new LoadOptions();
PdfDocument document = new PdfDocument(fs, options);

List<TextSearchInfo> results = document.FindText("Type 3 Fonts").ToList();

foreach (var match in results.SelectMany(x => x.Matches)) {
    var rects = match.MatchFragments
        .Select(x => x.Rectangle)
        .ToList();
    foreach (var rect in rects) {
        CircleAnnotation circleAnnotation = new CircleAnnotation(rect.BoundingBox)
        {
            Color = PdfColor.Red,
            Title = "Brian Zetc",
            Content = "This is a circle annotation."
        };
        document.Pages[match.PageIndex].Annotations.Add(circleAnnotation);
    }

}
document.Save(new FileStream("Demo2.pdf", FileMode.Create, FileAccess.Write));

VB.NET

Dim fs As FileStream = File.OpenRead("Demo.pdf")
Dim options As New LoadOptions()
Dim document As New PdfDocument(fs, options)
Dim results As List(Of TextSearchInfo) =
    document.FindText("Type 3 Fonts").ToList()

For Each match In results.SelectMany(Function(x) x.Matches)
    Dim rects = match.MatchFragments _
        .Select(Function(x) x.Rectangle) _
        .ToList()

    For Each rect In rects
        Dim circleAnnotation As New CircleAnnotation(rect.BoundingBox) With {
            .Color = PdfColor.Red,
            .Title = "Brian Zetc",
            .Content = "This is a circle annotation."
        }
        document.Pages(match.PageIndex).Annotations.Add(circleAnnotation)
    Next
Next
Using outputStream As New FileStream("Demo2.pdf", FileMode.Create, FileAccess.Write)
    document.Save(outputStream)
End Using
