Remove the small page icon on the corner of PDF file

Hello,

This is the first time i use PDFNet, and I notice that each PDF file rendered have a small "page" icon at the top left corner. When right click on it, a pop up show up with 2 button "Save", "Delete" and a big text box.

How can I hide this "page" icon?

Thanks

The page icon is the typical icon for what is called a “sticky note” in PDFs.

A StickyNote is an annotation.

To hide all annotations you can call PDFViewCtrl.SetDrawAnnotations()

To delete just the one sticky note, take a look at the AnnotationTest sample and you can see how to find and delete them.

Thanks. Problem solved
