Set the font color in prawn

Question

Im using prawn to generate a PDF output in a rails app. How do i change the color of the outputted text?

Answer 1

if you use any 1.x version (it's only a pre-release as of writing) you can also use:

Gem install:

$ gem install prawn --pre

Code:

require "rubygems"
require "prawn" 

Prawn::Document.generate "hello.pdf" do 
  text "Hello World (in blue)", :color => "0000ff", :size => 32 
end

Answer 2

Have you tried fill_color? Code below should work:

require "rubygems"
require "prawn" 

Prawn::Document.generate "hello.pdf" do 
  fill_color "0000ff" 
  text_box "Hello World (in blue)", :at => [200,720], :size => 32 
end
