'lo all

Apologies if this is an old topic, but I can't find anything in the
Flashcoders archives, and Google just throws up some gnomic "it's possible"
blog comments without any actual hints on *how* it's possible...

I'm attempting to perspective distort a bitmap to use as a floor in a
parallax scene - I achieved a similar effect in oldskool Flash 6 (lots of
progressively xscaled, 1px high masked MCs, yuck) at http://www.pd3.co.uk,
but I'm sure such a thing should be possible in Flash 8 using a
DisplacementMap filter.

Does anyone have a good idea how this could be achieved? I've been spending
a very long time staring at Photoshop, trying to come up with the right
combination of gradients for the displacement map, but all I have to show is
a headache and a nagging sense that I'm missing something...

Of course, a more direct approach would be to slice & scale the source image
using a whole bunch of draw()s and a Matrix with a changing xscale, but it
feels like a Displacement would be a cleaner option?

Happy Friday!
Henry
