Convert Prawn generated PDFs to an image with RMagick

You’ll see some complaining from RMagick about how the Prawn generated PDF is not 100% up to Adobe standards but that can be ignored.


pdf = Prawn::Document.new { text 'This is only a test.' }
base64 = Base64.encode64(pdf.render)
image = Magick::Image.read_inline(base64_pdf).first
image.write('test.png')
