I have a scanned document as a PDF that contains a column of personal medical info that I need to submit to someone. I want to cover up the column that contains the private info that I don't want anyone to see.
So, it seems that I can "highlight" a column of text in yellow (the default color). I'm thinking that if I can change the highlight color to black, I could effectively obscure the text.
Is there a way to change the highlighting color? I can't see to find the option.
