Simple image resizing module.
You should have graphicsmagick first:
# on debian based systems $ sudo apt-get install graphicsmagick # or maybe using homebrew $ brew install graphicsmagick
$ gem install imagery
require 'imagery' # - 48x48^ is the geometry string. This means we're resizing # to a 48x48^ constrained image # - 48x48 (second one) means we're cropping the image to an # extent of 48x48 pixels. i = Imagery.new(:photo, "1001", thumb: ["48x48^", "48x48"]) i.save(File.open('/some/path/to/image.jpg')) File.exist?('public/photo/1001/thumb.jpg') # => true File.exist?('public/photo/1001/original.jpg') # => true
For cases where we want to use S3 for some and normal filesystem for others.
class S3Photo < Imagery include Imagery::S3 s3_bucket "my-bucket" end # then maybe some other files are using cloudfront class CloudfrontPhoto < Imagery include Imagery::S3 s3_bucket "my-bucket" s3_distribution_domain "assets.site.com" end # some might be using S3 EU, in which case you can specify the s3_host class CustomS3Host < Imagery::Model include Imagery::S3 s3_host "http://my.custom.host" s3_bucket "my-bucket-name" end
You can check
Imagery::S3 to see an example of an extension.
