A ruby layer to make drawing SVGs easier. Uses rasem under the hood.
- A Canvas holds all the Items to be drawn.
- Group related shapes into an Item.
- Items can have sub-Items.
- The Canvas can be scaled (ie. zoom in/out).
- Individual Items can be scaled.
- Use coordinates as if you are drawing on the first Cartesian quadrant.
- Shapes can be snapped or unsnapped to each other (do they stay together or drift apart when scaled).
- Lines are drawn with a starting point, length and angle (versus two points).
Add this line to your application's Gemfile:
gem 'drawsvg'
And then execute:
$ bundle
Or install it yourself as:
$ gem install drawsvg
require 'drawsvg'
include DrawSvg
class StickMan < Item
def draw
@left_leg = Line.new(self, [0,0], 40, 60, stroke: 'red')
@right_leg = Line.new(self, @left_leg.p2, 40, -60)
@body = Line.new(self, @left_leg.p2, 30, 90)
@left_arm = Line.new(self, @body.p2-[0, 8], 30, 180+45)
@right_arm = Line.new(self, @left_arm.p1, 30, 20)
@box = Rectangle.new(self, @right_arm.p2, [10,15], fill: 'white', draw_from: :bottom_left)
@head = Circle.new(self, @body.p2, 15, draw_from: :bottom, stroke: %w[orange blue red].sample, fill: 'white')
end
end
class MyCanvas < Canvas
def draw
30.times do
StickMan.new(self, Point[(0..475).to_a.sample, (0..475).to_a.sample], scale: (50..150).to_a.sample.to_f/100)
end
end
end
canvas = MyCanvas.new(501, 501, nil, scale: [1.1, 1.0])
