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 logographic 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).
