Scripting the NVIDIA Texture Tools Photoshop Plugin?

I am interested in writing a custom Photoshop script (using their Javascript scripting option) - and am wondering of the Nvidia Texture Tools photoshop plugin is accessible through the Photoshop scripting platform?

I basically need to split my Photoshop image into a 4x4 grid - and export each sub image as a .dds. I would like this scripted because I need to do this to a lot of files - over 300.

Any ideas? Anyone ever tried scripting the Texture Tools plugin before?
