I would like to blacken some areas ("text") in a pdf-document.
I choose the "rectangle tool" with "Opacity" 100% and "Blend mode" "Color" [btw: what is the difference to "Hue"?]
Then I "print" it into a (new) PDF-document with FreePDF (or PDFCreator).
Now I cannot see the text "below" the rectangle.
Can the "text" really not be recovered?
Sincerely --- Uli
P.S: Maybe, there are better (free) tools to blacken
