Carrierwave add a watermark to processed images

Question

Im trying to add a watermark to processed images with below code I got from several resources:

def watermark
  manipulate! do |img|
    logo = Magick::Image.         


        

Answer 1

I just do it this way and it works very fine:

# Process files as they are uploaded:
process :resize_to_fill => [850, 315]
process :convert => 'png'
process :watermark

def watermark
  manipulate! do |img|
    logo = Magick::Image.read("#{Rails.root}/app/assets/images/watermark.png").first
    img = img.composite(logo, Magick::NorthWestGravity, 15, 0, Magick::OverCompositeOp)
  end
end
