NAME
       diffpdf - compare two PDF files textually or visually

SYNOPSIS
       diffpdf [file1] [file2]

DESCRIPTION
       This manual page very briefly documents the diffpdf command.  (Click the GUI's Help button or press F1 for more information.)

       DiffPDF is a GUI application used to compare two PDF files.
       By  default  the  comparison is of the words on each pair of pages, but comparing character by character is also supported (e.g., for logo-
       graphic languages). And there's also support for comparing the pages by appearance (for example, if a diagram is changed or if a  paragraph
       is  reformatted, or a font changed). It is also possible to compare particular pages or page ranges. For example, if there are two versions
       of a PDF file, one with pages 1-12 and the other with pages 1-13 because of an extra page having been added as page 4, they can be compared
       by  specifying  two page ranges, 1-12 for the first and 1-3, 5-13 for the second. This will make DiffPDF compare pages in the pairs (1, 1),
       (2, 2), (3, 3), (4, 5), (5, 6), and so on, to (12, 13).

       If the program is passed two PDF filenames on the command line it will start up and compare those files in Text mode (or in Appearance mode
       if the filenames are preceded by -a or --appearance).
