Image Sorcery allows you to leverage all three of ImageMagick's command line tools, mogrify, convert, and identify, for maximum magickal power and minimum memory consumption! It lets you use GraphicsMagick if that's you're thing, too.


At, we need server-side image processing to work well and bend to our will. I wrote this because the ImageMagick libraries we tried suffered from at least one of two problems:

  • Large memory consumption/leaking
  • Didn't expose the entire ImageMagick library

Due to the way Image Sorcery was written, it manages to avoid both of these problems.


gem install image_sorcery

Code Examples

image ="image.png")
image.identify # => "image.png PNG 500x500 500x500+0+0 8-bit DirectClass 236KB 0.010u 0:00.010\n"
image.manipulate!(scale: "50%") # => true
image.dimensions # => { x: 250, y: 250 }
image.convert("thumbnail.jpg", quality: 80, crop: "100x100>") # => true

Using GraphicsMagick

Assuming you have GraphicsMagick installed on your box:

image ="image.png")
# use as normal


  • Some more unit tests
  • A few more convenience methods (like "dimensions").
