Newbie in need of help CENTER_CONTENT

Question

I am working in Enfocus Switch and have a simple command that I need to execute in indesign (java in CS 5.5) I need to center all object inside their rectangle frame. But I dont know how to select an object in indesign and center the content (using Java). here is my best guess;
>>>   app.activeDocument.activeSpread.fit(FitOptions.CENTER_CONTENT(ALL));   <<<<<<
I understand I am probably way off, any help at all would be greatly appreciated!!!!
Thanks,
Paul Hough
Edit: I have figured out how to center the content inside of rectangles:
app.activeDocument.pages[0].rectangles[0].images[0].fit(FitOptions.CENTER_CONTENT);
But, I still dont know how to get a variable with the number of rectangles on a page/doc so I can create a loop.
Any tips or pointer are appreciated

Answer 1

Hi Paul
app.activeDocument.pages.everyItem().splineItems.everyItem().images.everyItem().fit(FitOptions.CENTER_CONTENT);
Will apply to all placed images outside  groups
app.activeDocument.pages.everyItem().groups.everyItem().splineItems.everyItem().images.everyItem().fit(FitOptions.CENTER_CONTENT);
Will apply to all the items in groups
The above is in Java Script and not Java.
