Creating LTL labels

label_generator.rb

  s           = Store.last
  s_name      = s.name.upcase
  s_address   = s.address.address_1 + s.address.address_2
  s_city      = s.address.city
  s_zip       = 'Zip: ' + s.address.zipcode
  label_path  = Rails.root.join('public', 'images', 'ltl_label.png').to_s
  barcode_file= "1318364275.png" ### <--- Aca ponete el string de un barcode que tengas en tu disco, en "public/images/barcodes/"
  output_path = "#{Rails.root}/tmp/ltl_label_#{barcode_file}"

  label = Magick::Image.read(label_path).first
  barcode = Magick::Image.read("#{Rails.public_path}/images/barcodes/#{barcode_file}").first
  barcode.resize!(140, 88)

  #### Adding From
  from = Magick::Image.new(150, 60)
  gc = Magick::Draw.new
  #gc.gravity = Magick::NorthGravity
  #gc.font_family = "Helvetica"
  #gc.stroke = 'none'
  gc.pointsize = 12
  gc.annotate(from, 0, 0, 10, 13, "#{s_name}\n#{s_address}\n#{s_city}\n#{s_zip}")

  result = label.composite!(barcode, Magick::SouthWestGravity, 13, 13, Magick::OverCompositeOp)
  result = label.composite!(from, Magick::NorthWestGravity, 13, 33, Magick::OverCompositeOp)

  result.write(output_path)
