| # Report changes in test images | |

| # This workflow checks for image diffs in a pull request and adds a GitHub | |
| # comment showing the diff. | |
| # | |
| # It is triggered in a PR when any *.png.dvc files have been added, modified, | |
| # or deleted. A GitHub comment will be published that contains a summary table | |
| # of the images that have changed along with a visual report. | |
