To whom it may concern, a way to create watermarks with ruby on rails, imagemagick, attachment_fu and mini-magick in Portuguese, but the code is in English;)
Tnks!
Well, another way is to do it within the paperclip plugin when files get uploaded.
It goes a lil' something like this:
----------- start extract --------- require 'paperclip'
class Image < ActiveRecord::Base belongs_to :parts
has_attached_file :info, :processors => [:watermark], :styles => { :mini => "60x60#", :thumb => "160x160#", :medium => { :geometry => "600>", :watermark_path => "#{RAILS_ROOT}/public/images/logo.png", :position => "SouthEast" }, :original => "1x1" }
validate :check_content_type
def check_content_type if !['image/jpeg', 'image/pjpeg', 'image/x-png', 'image/gif', 'image/png'].include?(self.info_content_type) errors.add( 'attachment,', "'#{self.info_file_name}' is not a valid image type") end end
end
----------- end extract ---------
