Thanks for this, looks like it improves the PDF quality in Firefox as well :) After: |

Looks good! Is there perhaps a reference to an issue (either on GitHub or Bugzilla), or does it not exist (yet)? If this improves a particular PDF file, would it be possible to add a reference test for this improvement so we avoid regressing it in the future or is it already covered by the existing reference tests?

I think this change is correct, with the two questions answered/addressed, and overall this seems like a good rendering improvement to me. It would be good though if @Snuffleupagus also signed off on this before merging, to make sure I didn't miss anything since this logic is important for rendering and it seems a bit tricky looking at how the spec describes it and how other viewers implement it.

Looks good to me, with the remaining comment above addressed (and the tests re-run if the change is made) and a check from @Snuffleupagus. Thank you for improving this!

@Snuffleupagus, gentle ping ? |
Sorry, last I looked at this there were still "open" review questions and then it slipped my mind (since I'm still short on time for open source stuff). |
and rely on the Interpolate flag only when the image is upscaled. Fixes mozilla#16273.
