Yes, Scanned PDF files can be Previewed as any other PDF file.
When the OCR scanning is done correctly, it will allow the best page feature to work.
However, sometimes there are some limitations depending on how the document was scanned and processed.
Simple way to find out if the PDF file is scanned:
- Is the content in the PDF file twisted or crooked in any way
- Are character, logo or picture of poor quality
Issues/limitation seen with some scanned documents – categories:
*1 PDF files that have not been OCR processed does not include the text but only images. (Best pages features and Hit highlighting will not be available)
*2 The document has been OCR processed and the text is placed in a hidden layer, only the image is visible. (If the text is placed in the hidden layer – usually behind the image – the highlighting will not show up in the preview as the hidden layer can’t be seen)
