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 even lets you use GraphicsMagick, too, if that's your thing.

Gem Version Build Status

Why?

At Fol.io, we needed 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 API

ImageSorcery doesn't try to be anything more than a wrapper that exposes the full ImageMagick and GraphicsMagick APIs. This makes it small and powerful, eliminating the above problems.

Installation

gem install image_sorcery

Code Examples

image = ImageSorcery.new("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
image = ImageSorcery.new("multi-page.pdf")
image.filename_changed? # => false
image.manipulate!(format: "png", layer: 0) # => true
image.filename_changed? # => true
image.file # => "multi-page.png"
image = ImageSorcery.new("multi-page.pdf")
image.manipulate!(format: "png") # => true
image.filename_changed? # => true

# on ImageMagick it returns all layers as a single file
image.file # => "multi-page-*.png"

# on GrapicksMagick it returns only the fist layer
image.file # => "multi-page.png"

Using GraphicsMagick

Assuming you have GraphicsMagick installed on your box:

image = ImageSorcery.gm("image.png")
# use as normal

Todo

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