Guide when Flexcil gestures do not work
Text selection gesture may not work in scanned documents or image-based documents.
Scanned documents / image-based documents
Image-based PDF documents do not contain text data internally. Therefore, gestures such as text selection, underline, circles, parentheses and etc. do not work. However, image capture gestures such as square and L-shape gestures are also available in image documents. In the case of these documents, you can use gestures if you process OCR (Optical character recognition) through a separate tool or service.
