If the document is a scanned one or converted from image, text selection gestures(Underline, Parentheses, Small circle, Large circle, etc.) will not work.
Scanned or image-based document
If the document is a scanned document or the document converted from an image, the document doesn't contain the text data. For this reason, text selection gestures (Underline, Parentheses, Small circle, Large circle, etc.) will not work.
To use gesture functions on the scanned or image-based document, you need to run OCR(Optical character recognition) processing.
You can still use image selection gestures(Square, L) on the scanned or image-based document.
