newbie: read/write psd file from app other than photoshop

[_cuongvt_]

Hi all,
I would like to clarify some technical items as below:
1) Can I use photoshop SDK to build independent desktop app (not photoshop plugin) to read/write/edit psd file? If yes, is there any license rule I must follow?
2) Can I use photoshop API to build more module to read/write/edit psd file,
then use this core module to build complete web-based app with wonderful flex as front-end and that core module is back-end?

If both above 2 items it not capable of implementing, is there another way to build independent desktop app or web-based app for read/write/edit psd file?

Please help me. I need your help.
regards

It depends how much PSD functionality you need. Most of it is not documented, but the basic stuff is.

Refer to PS "Advanced" SDK. For source code to a PSD/PSB file reader, see my http://telegraphics.com.au/svn/psdparse/trunk
