scale image only width with minimagick in ruby on rails 3

minimagick, rmagick, ruby-on-rails, ruby-on-rails-3

Solution

It's actually quite easy to do this. Here's an example:

  version :column do
    process :resize_to_fit => [250, nil]
  end

This version will be rescaled so that the width is the specified value (250, in my case), and will retain the aspect ratio.

Problem

I am using this method for resize the images: ``` version :big do process :resize_to_fit => [560, 200] process :convert => :png end ``` But with this method I have that write a height fixed. I want only scale or resize the width image. I want the height of the image is automatic and scale the image to the width that has been given. How can I scale or resize, only the width image? I'm using minimagick with carrierwave.
