Food for thought... Skia's "skdiff" tool generates two diff images for each image pair:
- 1. every pixel which is different at all between images 1 & 2 shows up as white - 2. every pixel shows the color difference between images 1 & 2 (much more subtle) For an example of what this looks like, see http://skia.googlecode.com/svn/trunk/tools/tests/skdiff/test1/output-expected/index.html On Fri, Jun 15, 2012 at 7:24 PM, Tony Payne <[email protected]> wrote: > I would like to change chromium's ImageDiff to reflect the magnitude of > pixel changes.
