Photoshop CS4 SDK and 64-bit Windows

[ttwn]

Will there be an SDK for 64-bit Windows or do we just use the CS3 SDK and compile plug-ins in x64 mode?

Does CS4 support both 32-bit plug-ins and 64-bit plug-ins when the 64-bit version of Photoshop is installed?

That's a very good question, Tom.

I'd be interested to know how I can make my plugins run on 64-bit CS4.

Well, now that Photoshop CS4 has released, we have some answers. Yes, there is an SDK at http://www.adobe.com/devnet/photoshop/sdk/. Yes, both 32-bit and 64-bit environments are supported on Vista-64. This is done by installing 32-bit and 64-bit versions of Photoshop.

Nicely done!

From what I can see the plugin interface is virtually identical between 32 and 64 bits, the code just needs a rebuild in many cases. Of course, design changes may be in order if a particular plugin needs 64 bit capability to exceed boundaries.
