Hi everybody,
I just had a bit of a flashbulb going off a few days ago
and I thought I'd share it with you.
I work in the Visual Effects industry and we constantly
have to compare almost identical versions of the same
image. The way we do this, beside a standard side-by-side
comparison, is to quickly (but manually) switch from one
image to the other, back and forth, so that our eyes can
easily pick up the differences (*).
I thought this could be useful to extend the wiki way
of doing things to images, especially SVGs. The history
interface would remain the same but the browser would
put the two images on two different layers, one obscuring
the other, and a simple button would allow (ideally through
javascript) to swap the two quickly. Of course a standard
diff would then be available to inspect the differences in the
actual code if the image in question is SVG.
What do you think?
Ciao!
Manu
(*) human eyes are excellent at picking up changing details
in an unchanging scene. Interestingly, they are also very
good at picking up still details in a rapidly changing scene.
This is probably due to the first case representing a prey
or a predator in an otherwise unchanging landscape, and
the latter case representing a static prey or predator in
a view with lots of moving features, i.e. leaves and branches.
