diffpdf - compare two PDF files textually or visually
This manual page very briefly documents the diffpdf
command. (Click the
GUI's Help button or press F1 for more information.)
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).
