Jpeg 2000 save options


I actually have a script that use this save options in PhotoShop CS:

set myOptions to {class:JPEG save options, quality:12, embed color profile:true}

I have the plug-in intalled for Jpeg 2000 but there is no «save options» class for this.

Can I create a class in PhotoShop or should I do otherwise to save at maximum quality, in this case «Quallity 100».

Many thanks
