comparepdf [options] file1.pdf file2.pdf
The default comparison mode is text mode where the text of each
corresponding pair of pages is compared. As soon as a difference is
detected the program terminates with a message (unless -v 0 is set) and
an indicative return code.
There are two comparison modes (-c or --compare):
t/text(default): Compare only the textual content of the PDFs.a/appearance: Compare the PDFs visually.
There are three verbosity levels (-v or --version):
0: No text output1(default): Text output only for differences2: Text output for matching and differing files
- C++ compiler
- CMake and KDE's Extra CMake Modules
- Qt 5 libraries
- Poppler libraries
Linux and BSD users should be able to get everything through their package management system — and some distros already include comparepdf so you don't even have to build it.
Mac OS X users can get a compiler by installing Xcode; you'll need to get Qt and Poppler separately.
