I was wondering if anyone has had any experience working with Replacement Text annotations with PDFBox. I am currently working on a project which involves, in part, transferring annotations from one PDF to another. The PDFs are actually the same PDF, the only difference is in the annotations. I am having an issue when it comes to Replacement Text annotations, because they come up in PDFBox as type PDAnnotationUnknown and when copied over, the only thing which is copied is the text. The popup is lost as well as the line which crosses out the text which the annoter (is that a word?) intends the text to be a replacement of.
In contrast, everything works great with annotations created using the regular Note Tool. For each note PDFBox finds 2 annotations, one of type PDAnnotationText, which is the actual comment and one of PDAnnotationPopup which is the popup that the text is contained in. In addition, you can easily find the relation between these two annotations by using getParent from PDAnnotationPopup or getPopup from PDAnnotationText. For Replacement Text annotations, only a single annotation is found by PDFBox, of type PDAnnotationUnknown. Any information anyone can provide on this would be appreciated. My only thought is that perhaps this is a newer feature which is not really supported by PDFBox yet.
