Photoshop CS4 SDK

What's new

Adobe Photoshop CS4 now runs as a native 64 bit application on Windows Vista 64 operating systems and hardware. Photoshop plug-in developers will need to use the SDK to update plug-ins to run with the 64 bit version of Photoshop.

Developers will need to meet the requirements before proceeding with converting a plug-in conversion:

• Adobe Photoshop CS4 Windows
• Adobe Photoshop CS4 SDK
• Microsoft Visual Studio 2005 Professional Edition (64 bit tools installed)
• Microsoft Windows Vista 64

The SDK provides details in converting the Dissolve example plug-in. See the "Making 64 bit plug-ins" page in the documentation section of the SDK after downloading.
