The viewer supports pulling artifacts based on PR number, and now
we support providing Run ID as an alternative to identify the
renderdiff run on Github CI.
- Move upload step to later so that comparison result is also
included in the upload
- Fix the wrong relative paths in the comparison_result.json
- Fix viewer logic to pick only the latest run for a PR.
- Modify the compare script to output more details of a
comparison. This will include the source/golden directory,
the comparison directory (the new renderings), and a file
path to difference images if the golden does not match
the rendered image.
- The image_diff script can now output a TIFF that is the
difference of two input TIFFs.
- Add a viewer for examining the differences between rendered
output and golden images.
- The viewer consists of a simple server of web API endpoints
for querying difference results (along with rendered images
in TIFF).
- And a web-based (html + lit-element) UI for looking at the
rendered images and differences.
