How to visually compare two PDF files? (cont’d)

When I asked the above question in a Telegram group, people proposed also other tools, which I am summarizing below.
Amiad Bareli, Amit Aronovitch, Meir Gil and Yehuda Deutsch – thanks.

  1. ImageMagick compare
  2. matplotlib testing framework – supports also PDF: 
    >>> import matplotlib.testing.compare
>>> matplotlib.testing.compare.comparable_formats()
['png', 'eps', 'svg', 'pdf']
  3.  pHash – The open source perceptual hash library.

I am deaf since birth. I played with big computers which eat punched cards and spew out printouts since age 12. Ever since they became available, I work and play with desktop size computers which eat keyboard keypresses and spew out display pixels. Among other things, I developed software which helped the deaf in Israel use the telephone network, by means of home computers equipped with modems. Several years later, I developed Hebrew localizations for some cellular phones, which helped the deaf in Israel utilize the cellular phone networks. I am interested in entrepreneurship, Science Fiction and making the world more accessible to people with disabilities.
