Post subject: | Exception in PdfPage.HasAnnotations when no annotations on p |
This is from https://github.com/empira/PDFsharp/ which I just pulled down today. In PdfPage.cs line 383 The code throws an exception if the page does not have annotations because it tries to assign `this` when it have already established that _annotations is null, and GetValue doesn't create a new object. Code: public bool HasAnnotations
{ get { if (_annotations == null) { // Get annotations array if exists. _annotations = (PdfAnnotations)Elements.GetValue(Keys.Annots); _annotations.Page = this; } return _annotations != null; } } |
