Control Page Size

[dmoulton]

Using shrimp and phantomjs with rails 4 and middleware. I am wondering if and how its possible to change the pdf page size on the fly. I've been setting it in the initializer. Is it possible to change it on each call?

pdf = Shrimp::Phantom.new(
  url + "?#{query}",
  margin: '0cm',
  format: 'A4'
)
