Imagery

Simple image resizing module.

Prerequisites

You should have graphicsmagick first:

```bash # on debian based systems $ sudo apt-get install graphicsmagick

or maybe using homebrew

$ brew install graphicsmagick ```

Installing

bash $ gem install imagery

Usage

```ruby 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 ```

Advanced Usage (S3)

For cases where we want to use S3 for some and normal filesystem for others.

```ruby 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 ```

Extending

You can check Imagery::S3 to see an example of an extension.
