Unfortunately, I cannot share the file as it is from a client.

I have a PDF file from a client that is signed and appears to have form fields. When I read the text in the file using page.Text.GetTextInfo there is text enclosed in open and closed brackets [] that does not appear in the viewer. I'm assuming this has something to do with form fields. I would like to extract the text from the file and not include text that does not appear in the viewer. Is there a way to determine if text in between open and closed brackets is visible to the user in the viewer?

Thanks,

Ted
