How to crop photos in paperclip?

Question

Ruby on Rails

Let's say I set it up like this:
has_attached_file :image, styles: { preview: "250x150>"}
If I upload an image sized 200 by 600. Then 600 pixels turn into 150, and 200 proportionally into some more.
But how can I make the size change so that the picture will occupy all 250 by 150 and some part will be cut off?

Answer 1

has_attached_file :image, styles: { preview: "250x150#"}

I think it used to be

Answer 2

has_attached_file :image, styles: { thumb: "100x100"},
convert_options: {preview: "-gravity north -thumbnail 250x150^ -extent 250x150"}
