Hello,

Maybe reach out to volunteers to find out images candidates and the
tests we want to run on them (such as: imagemagick, vips, vips+bilinear).

Imagemagick comes with a comparaison tool that let you generate a diff
image: http://www.imagemagick.org/script/compare.php


>From there, with some magic shell script wrapper, we could have a
Jenkins jobs that will run:
 - fetch the pictures from commons
 - run all the scaling tests for us
 - copy the generated thumbnail + the compare output to some public
place ( such as integration.wikimedia.org )
 - generate a HTML page including all the thumbnails

The job can be triggered whenever a patch is sent against the VipsScaler
extension and we can make Zuul to report back in Gerrit the link to the
HTML page :)

I will definitely not have the time to handle that myself by the end of
July but if someone manage to figure out the tests and write a basic
shell wrapper  it is pretty trivial to create the Jenkins job :)
