In one of my latest projects i was using the attachement_fu plugin to handle image uploads.
The attachement_fu plugin enables the option to select an image processor engine between ImageScience, Rmagick add MiniMagick:

1. Rmagick
   Kinda bulky, leaking but fully functional
   
2. MiniMagick
   Simple version of Rmagick, simple and small.
3. ImageSceince
   Small, nice, and quick.

i decided to use MiniMagick as my processor, i installed the gem:

sudo gem install mini_magick

and added a specific :processor option to my Logo model.

has_attachment :content_type => :image, 

                  :storage => :file_system, 

                   :max_size => 2.megabytes,

                   :resize_to => ‘x100’,

                   :processor => :mini_magick

but when i was uploading an image, i was was expecting it to be resized based on the options i specified in the model. imagine how surprised i was when i found out that the image is not being resized.
checking the log found the following error:

Exception working with image: ImageMagick command (identify “/var/folders/Bv/Bvbna8-OH548ZWju8naF4U+++TI/-Tmp-/minimagick11451-0”) failed: Error Given 32512

Googling it didn’t help me much (except from finding other people with the same problem), so i decided to switch to use ImageScience instead (RMagick is out of the question of course).

sudo gem install image_science

this will include all most all dependencies, but the freeImage dependency is also needed.
us mac/darwin users can simply use port:

sudo port selfupdate

sudo port install freeimage

now change the processor in the model

has_attachment :content_type => :image, 

                   :storage => :file_system, 

                   :max_size => 2.megabytes,

                   :resize_to => ‘x100’,

                   :processor => :image_science

and now it’s working. yeah!.
