I need to write a Java script to make my Art board bigger by 1 (one) inch on the Width and Length, Regardless of the Content?

Question

Hi,
I am currently using "Visible bounds" (java script)to add 1 inch to the width and to the Length of my Art board, but when i make a clipping mask it actually reads the hidden content from the Clipping mask and makes conforms my art board to that particular shape. Am using Adobe illustrator cs6 Here is My Code:
var myDocs = app.documents;
var i = 0;
for (i = myDocs.length-1 ; i >= 0; i--)
    var doc = myDocs[i];
    app.activeDocument= doc;
    var myVisibleBounds = doc.visibleBounds; //Rect, which is an array;
    myVisibleBounds[0] -= 36;
    myVisibleBounds[1] += 36;
    myVisibleBounds[2] += 36;
    myVisibleBounds[3] -= 36;
    doc.artboards[0].artboardRect = myVisibleBounds;
All i Want is to add 1 inch to my width and length and this does it but if i have a clipping mask it will pick up the bounding box i guess? and it will conform it to the shape... any help please... Try my code and you will see that it does add 1 inch but now make you artboard lest say 12" x 12" and make a shape bigger than the art board and you will see how it adds 1 inch to the art board based on that shape...  now if you make a clipping mask to fit that shape in the 12" x 12" art board you will still get 1 inch bigger than the shape thats being clipped ... 

Answer 1

yes, visible bounds is reading the non-visible masked objects too.
you're going to have to do it the hard way, loop through all your objects to get your bounds manually, and while you're at it, test for clipping masks and use the masking path instead.
