Installation

Add this line to your application's Gemfile:

gem 'imager'

And then execute:

$ bundle

Or install it yourself as:

$ gem install imager

Usage

Imager.configure do |c|
  c.base_uri          = "http://files.myserver.com"
  c.manager_path      = "manager"
  c.collections_path  = "images"
  c.auth_code         = ""
end

c.auth_code is the $YOUR_AUTH_CODE = ''; you setted in the [server] (https://github.com/guilherme-otran/ImagerServer). This is for post and delete authentication (manager).

Sending the images

Imager::ServerInterface.post("Collection", "Album", "test/imageid.png", small: { width: 100 })

Creates:

http://files.myserver.com/images/Collection/Album/imageid/small.jpg

And

Imager::ServerInterface.post("Collection", "Album", "test/image.png", small: { width: 100 }, "someimageid")

Creates

http://files.myserver.com/images/Collection/Album/someimageid/small.jpg

Removing the images

Imager::ServerInterface.delete("Collection", "Album", "imageid")

Using the images

Imager::LinkHelper.link_for("Collection", "Album", "imageid", :small)

Will return: "http://files.myserver.com/images/collection/album/image/small.jpg" Since the server ALWAYS save the images as jpg.

You can use Collection as model name(product) and album as id(1) and get the result:

"http://files.myserver.com/images/product/1/image/small.jpg"

Just save as: Imager::ServerInterface.post("product", "1", "test/image.png", small: { width: 100 })

Notes about saving and sizes

Saving first as "product", "1", "test/image.png", small: { width: 100 }) and after "product", "1", "test/otherimage.png", small: { width: 90 }) don't changes the size of image. Beware!

Sizes Explain:

The server accepts the following combinations:

YourSizeName: :original       # Will save the original size. Don't worry. The server compress to 50% of quality.
YourSizeName: { width:  100 } # Will resize (maintein main aspect) the image for 100px of width
YourSizeName: { height: 100 } # Will resize (maintein main aspect) the image for 100px of height
YourSizeName: { width:  100, height: 150 } # Will resize to fit in 100x150 px

You can have many sizes when posting a image:

sizes = {
  small:     { width:  100 },
  gallery:   { height: 300 },
  mini-home: { width: 50, height: 50 },
  original:  :original
}

Compression

The images always are compressed to 70%. Except for the original size (50%).
