Looking for an acrobat script to delete blank pages

I need an acrobat script to delete blank pages. By blank, I mean TRULY blank, with nothing on them.

I found this script: but it just looks for pages without text content. So it also ended up deleting pages that had vector graphics on them.

for(var i=this.numPages-1;i>=0;i--)
{
  if(this.getPageNumWords(i)==0)
    this.deletePages(i);
}

Can anyone help by making this script just apply to truly blank pages? Alternatiely, it would work if it only looked at 11"x17" pages and deleted the blank ones.
