Question

I would like to set not square image to square and use for this square center of image. How to done it with paperclip?

Answer 1

This will take an image, crop in the center of the image at 500×500, then throw everything else away, then resize that new image back down to 100×100. It’s used for generating square thumbnails, but you can adjust this for your needs.

has_attached_file :image,  
  :styles => { :thumb => "" },
  :convert_options => { 
    :thumb => "-gravity Center -crop 500x500+0+0 +repage -resize 100x100^", 
  :default_style => :thumb
