Using Rmagick to process images from buffers instead of file paths
Raw
About.md

Most documentation for Rmagick that I found shows you how to read images into an Rmagick object from a file path. However, I have a situation where I had a file stored in a MongoDB database and needed to process it with Rmagick.

The from_blob method did this for me. In a single line, I was able to read the file from the database into a buffer and pass that directly to Rmagick! :)

gistfile1.rb
img = Magick::Image::from_blob(@document.file.read)
