How to set flattening option on EPS file

Hello,

I need to set within a javascript script the flattener options and I don't know how to do it. I have seen the option for an pdf file flattenerOptions that doesn't exist on an EPSSaveOptions object..

Basically what I need to do is replicate the High Resolution transparency preset like describe Automate Loading of Transparency Flattener Preset but the option doesn't seem to exist for an EPS file.

At this point I am stuck, any help would be appreciated.

Thanks Raphael
