Constructor Details

#initialize(x = 0, y = 0, text = nil, &block) ⇒ Text

Define a text string starting at [x, y]. Use the RVG::TextConstructors#text method to create Text objects in a container.

container.text(100, 100, "Simple text").styles(:font=>'Arial')

Text objects can contain Tspan objects.

container.text(100, 100).styles(:font=>'Arial') do |t|
   t.tspan("Red text").styles(:fill=>'red')
   t.tspan("Blue text").styles(:fill=>'blue')
end
