How does Content-DPR relate to this? I thought this was only about EXIF? What would be interesting to see:

Oops, probably a copy-paste thing (this is based on old content-dpr tests, as it has a similar purpose)
Sure, I can add that.
yea I can try to integrate exiftool into WPT-runner... let's see how that works |
These test include images that have EXIF values that specify density-corrected size And they assert that the intrinsic size for those images is corrected by that EXIF. WhatWG PR: whatwg/html#5574

New patch uses piexif.js to generate density-corrected size images on the fly. |

@foolip - can you take a look at the third-party code here and make sure this is the right way to land it? |
|
@yoavweiss how to include third party JS is the topic of web-platform-tests/rfcs#46, which isn't resolved yet, but I'd recommend following the suggestion in web-platform-tests/rfcs#46 (comment). That is, put it in a |
