vslavik/diff-pdf: A simple tool for visually comparing two PDF files
diff-pdf is a tool for visually comparing two PDF files. By default, it outputs a return code indicating whether the PDFs differ. With the `--output-diff` option, it generates a PDF highlighting the differences. Using the `--view` option, a simple GUI allows visual comparison. The tool can be installed on Windows using Chocolatey, on Mac with Homebrew or MacPorts, and on Unix systems using common package managers. Compilation from source requires dependencies like wxWidgets, Cairo, and Poppler.
