[bmorris3]

Description

Allow users to take advantage of PNG compression via ImageGL from glue-viz/bqplot-image-gl#109. Bumping pin for bqplot-image-gl.

The visual change is ok, so we can put the hash somewhere to indicate this is good, this should be documented at https://pytest-mpl.readthedocs.io/en/stable/hash_mode.html

Do you want to try this @bmorris3, or should we ask @astrofrog ?

[dhomeier]

@Carifio24, @astrofrog, are there any tools to run the deploy-reference-images job for updating the reference hashes in glue-jupyter-visual-tests, and does one need special permissions for that?

[bmorris3]

I experimented a bunch, and settled on generating updated hashes with:

tox -e py311-test-visual -- --mpl-results-path=results

I've put the resulting hashes in the latest commit, I guess we'll see if that's ok?

[dhomeier]

The scatter2d images apparently have not changed at all.

@dhomeier the CircleCI job updates the reference images

@dhomeier the CircleCI job updates the reference images

Did you enable that job somehow? I noticed one job that required approval before, but first wanted to fix the checksums, and now it seems to have disappeared again.

[astrofrog]

@dhomeier - the job to update the reference images only happens on main after a PR has been merged. All that is needed for a PR to pass is for the hashes to be correct.

Thanks all!
