Prawn没有绘制横向规则

I want to draw a simple horizontal rule. What I'm doing is:

我想绘制一个简单的横向规则。我在做的是:

move_down 30
horizontal_rule

and Gemfile

gem 'prawn', :git => "https://github.com/prawnpdf/prawn.git", branch: 'master' 

It doesn't draw anything.

它没有任何吸引力。

You need to call horizontal_rule inside a stroke do block, i.e.

你需要在stroke do block中调用horizo​​ntal_rule,即

stroke do
  move_down 30
  horizontal_rule
end

Alternatively you can call the method, stroke_horizontal_rule.

或者,您可以调用方法stroke_horizo​​ntal_rule。

move_down 30    
stroke_horizontal_rule

If you want to use other options such as color, width etc I think you have to do it in the block...

如果你想使用其他选项,如颜色,宽度等我认为你必须在块...

stroke do
  stroke_color 'ff0000'
  dash(5, space: 2, phase: 0)
  line_width 10
  stroke_horizontal_rule
  move_down 15
  horizontal_line(0, 540)
end
