Draught - a Geometry library for creating vector graphics
draught, v.
- To make a plan or sketch of; esp. to draw a preliminary plan of (something to be constructed); to design. (Sometimes draft.)
Draught is a library for creating vector graphics as PDFs. It's grown out of generating shapes that can be laser cut, and that's still its focus.
TODO: Explain the fundamental concepts
Installation
To use it as a library add this line to your application's Gemfile:
gem 'draught'
And then execute:
$ bundle
Or install it yourself as:
$ gem install draught
Usage
Example docs are bad and I will fix them.
Also having to require everything individually.
Create a simple straight line and add it to a sheet, then generate a PDF with it:
require 'draught/line'
require 'draught/bounding_box'
require 'draught/sheet'
require 'draught/renderer'
line = Draught::Line.horizontal(100).translate(Draught::Vector.new(100,100))
box = Draught::BoundingBox.new(line)
sheet = Draught::Sheet.new(width: 300, height: 200, containers: [box])
renderer = Draught::Renderer.render_to_file(sheet, './example.pdf')
Development
After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
