How to set width only for loaded clip image?

Question

I am loading a large image into my model using Paperclip. I would like to set only the width of the image and let it automatically resize the height.

has_attached_file :picture, :styles => { :large => "900", :medium => "300x300>", :thumb => "100x100>" }, :default_url => "/images/:style/missing.png" 

In sizes :medium and :thumb I set both height and width. Q :large I just want to set the width and let it be as high as it should be.

Any suggestions?

Answer 1

Try using :large => "900x" . This should change the width to the desired value and keep the original aspect ratio.

Answer 2

Width Only :large => "900"

Height Only :large => "x900"
