Its definitely better than nothing.

I somehow thought there are some image comparison packages inside Debian.
A short search has lead me to

   https://softwarerecs.stackexchange.com/questions/9774/command-line-tool-to-check-whether-two-images-are-exactly-the-same-graphically

which recommends

   identify -quiet -format "%#" images...

Please note that I used xz compression on the xml data to save some
space also on developers machines.  I've also called routine-update -f
to update the packaging.  I do not think that the image comparison is
mandatory here - its way better to test at all than to make it perfect.
But if you want to give identify a try that would be fine.

However, we have a remaining problem in my pbuilder chroot:


autopkgtest [19:32:42]: test run-unit-test: [-----------------------
run-detectors: unable to find an interpreter for /usr/bin/cgview
autopkgtest [19:32:43]: test run-unit-test: -----------------------]
autopkgtest [19:32:43]: test run-unit-test:  - - - - - - - - - - results - - - - - - - - - -
run-unit-test        FAIL non-zero exit status 2


It somehow sounds similar to this thread:

    https://lists.debian.org/debian-java/2016/04/msg00098.html

I'd recommend to check with debian-java@lists.debian.org .  In
the case of artfastqgenerator I've circumvented the problem
a wrapper script.

Hope this helps

       Andreas.
