Letter spacing about prawn HOT 7 CLOSED

I noticed prawn-format has some support for this. You can add something like

if options[:letter_spacing]
  state[:text].character_space(options[:letter_spacing])
end

to Line#draw_on and then do something like

text "foo", :letter_spacing => 123

, but this messes up line wrapping and likely a bunch of other things.

Maybe someone can build on it, though.

Patches are welcome for this feature but they need to be well tested and come with examples.

If it helps someone else, I ended up faking it (in Rails, hence the chars) like this:

require "prawn/format"
my_string = "some text\nsome more"
spaced_string = my_string.lines.map {|line| line.chars.split('').join('<space></space>') }.join('<br/>')
text spaced_string, :tags => { :space => { :width => '1' } }  # fake letter-spacing

Hi, thank you, I have something like the following in my rails/lib now

class Prawn::Document
  def text_spaced text, options = {}
  
    spaced_string = text.lines.map {|line| line.chars.split('').join('') }.join('
')
    text spaced_string, {:tags => { :space => { :width => (options[:letter_spacing] || 1).to_s } }}.merge(options)  # fake letter-spacing
  end
end

cheers. Marco

Please don't post prawn-format related examples here until prawn-format is maintained. They are only relevant to Prawn <= 0.6.x

Since I've rewritten text and written formatted text, it would be most straightforward for me to take this on.
