indesign script to check and apply Image Color Settings?

Hello, I need to write an InDesign script that can query and modify the state of the "Profile:" and "Rendering Intent:" attributes in InDesign's "Image Color Settings" dialog box for selected placed pictures:

I saw the example "colorSettings.jsx" someone mentioned in another post, but that script merely launches the above dialog box. Any help or example on how to locate these two attributes within an InDesign Javascript would be greatly appreciated. Thank you.
