# 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")
|
|
end
