+To generate the blurhash string from an image file, you need to read in the image pixel data yourself, for example with RMagick:
 
 ```ruby
 require 'blurhash'
 require 'rmagick'
 
 image = Magick::ImageList.new('foo.png')
 
 puts Blurhash.encode(image.columns, image.rows, image.export_pixels)
 ```
