Is there any PDF reader that has a highlighting function that DOES NOT require OCR?

For many of the PDF readers I’ve used, they all have a highlighting function, but they all have to have the characters recognized as actual text. When I try to use OCR, the characters are lopsided if the scanned book page isn’t exactly straight and I can’t read it. So, I just want to draw yellow line on whatever I want to highlight. Is there any PDF reader/editor that can do this?
