我有这个代码来创建一个 RTF 文档,但我找不到如何为文本着色,有人可以帮我吗?
# encoding: utf-8
#!/usr/bin/env ruby
$LOAD_PATH.unshift(File.dirname(__FILE__)+"/../lib/")
require 'rtf'
include RTF
colour = Colour.new(150, 150, 150)
style = CharacterStyle.new
style.bold = true
style.font_size = 28
style.foreground = colour
document = RTF::Document.new(RTF::Font.new(RTF::Font::ROMAN, 'Times New Roman'))
document.paragraph(style) do |p|
p << "And there you have it."
end
File.open('my_document.rtf', 'w') {|file| file.write(document.to_rtf)}
