possible to import images from disk, scanning devices, clipboard and
screenshots.  gImageReader also supports multipage PDF documents.
Recognized text is displayed directly next to the image and basic text
editing including search/replace and removing of line breaks is
possible.  Spellchecking for the output text is also supported if the
corresponding dictionaries are installed.")
