What is the difference between the Text over the page image and Text under the page image options in Searchable PDF format settings for FineReader PDF?
Text over the page image
This option saves the background and pictures of the original document and places the recognized text over them. The resulting PDF document will be fully searchable. In some cases, the appearance of the resulting document may slightly differ from the original.
Text under the page image
This option saves the entire page as an image and places the recognized text underneath. The text layer makes it possible to search the document and copy text, while the page images insure that the document looks virtually the same as the original.
