+# Build nanDECK directive files in Ruby
+
+[nanDECK](http://www.nand.it/nandeck/) is a tool used by game designers to build
+decks of cards quickly using a series of drawing directives. There's some abiliity
+for iterating over data and using variables, but not with the same flexibility
+that a full-blown scripting language like Ruby can offer. `nandeck-ruby` provides
+a series of primitives, composite objects, and boilerplate classes that let you
+quickly build nanDECK files from a set of data from, say, a Google Drive
+spreadsheet.
+
+## Usage
+
+``` ruby
+require 'nandeck'
+
+class Card
+  def self.width
+    2.5
+  end
+
+  def self.height
+    3.5
+  end
+
+  def self.border
+    0.125
+  end
+
+  def self.real_border
+    border * 2
+  end
+
+  def self.pixel
+    0.03
+  end
+end
+
+output = []
+output += Nandeck::CardSize.new(300, Card.width, Card.height).to_a
+output += Nandeck::PageSize.new(8.5, 11, :portrait).to_a
+output += Nandeck::Margins.new(0.5, 0.25).to_a
+output << "OVERSAMPLE = 2"
+output << "IMAGEFILTER = Lanczos"
+
+output << Nandeck::Rectangle.new(1, 0, 0, Card.width, Card.height, '#000000', '#ffffff', Card.border)
+output << Nandeck::Image.new(1, "images/background.png", 0, 0, Card.width, Card.height, flag: 'P', alpha_channel: "10@270")
+
+area = Nandeck::Geometry.new(Card.border + 0.05, Card.real_border + 0.05, 0.688, 0.640)
+output << Nandeck::Image.new(1, "images/balloon.png", *balloon.to_a)
+
+Nandeck::Font.for(typeface: "Tahoma", flag: 'T') do |font|
+  height = 0.41
+
+  font.for(size: inches_to_points(height), color: "#000000") do |balloon_font|
+    x, y = balloon.center.to_a
+
+    output << balloon_font.text(1, "5", x - height / 2 - 0.10, y - height / 2 - 0.10, height + 0.20, height)
+  end
+end
+
+line_height = 14
+
+Nandeck::Font.for typeface: "Tahoma", size: line_height, flag: "TB", color: '#000000' do |font|
+  font.for color: '#ffffff' do |outline|
+    output << Nandeck::TextBlock.new(1, outline, "name", 16, 0.90, Card.real_border + 0.1, Card.width - Card.real_border - 1.00, 0.38, outline: Card.pixel * 2)
+  end
+
+  output << Nandeck::TextBlock.new(1, font, "name", 16, 0.90, Card.real_border + 0.1, Card.width - Card.real_border - 1.00, 0.38)
+end
+
+File.open("output.txt", "w") do |fh|
+  fh.print output.collect(&:to_s).join("\n")
