### Parsing PowerPoint Files and Extracting Content with RubyPowerpoint

Source: https://github.com/pythonicrubyist/ruby_powerpoint/blob/master/README.rdoc

This Ruby code demonstrates how to parse a `.pptx` file using `ruby_powerpoint`. It initializes a `Presentation` object, then iterates through each slide to extract its content (text), title, and image byte streams. It also shows how to save an extracted image to a file.

```Ruby
require 'ruby_powerpoint'

deck = RubyPowerpoint::Presentation.new "specs/fixtures/sample.pptx"

deck.slides.each do |slide|
  slide.content # => ["Presentation Notes...", "12345"]
  slide.title # => "Prsentation Header"
  slide.images # => ["\xE3=\xA8h\x8E\x17\...."] Byte Stream
  # Saving the image byte stream to a file:
  File.open('temp.jpg', 'w'){|f| f.puts slide.images[0].read}
end
```
