Decouple the Interpolations class from the Attachment classs, you can extend Paperclip with custom interpolations as paperclip-extended does.

Abstract out the file geometry parser within Thumbnail. This makes it possible to have different cropping and scaling controls, as the papermill gem does.

I think it's OK to have the bugfix for MongoDB in the plugin.

This reverts commit cde22564.

This reverts commit fe01ae69.

We already merged it in 6a10b358 and 0708cd43

This reverts commit ff3929ee.

Add ability to specify ".allowing" and ".rejecting" individually with content_type validation matcher.

Closes #472, Closes #532

Closes #515

option to convert.

Closes #170

added :preserve_files option so paperclip can get along with soft-delete plugins like acts_as_paranoid

Closes #152

Closes #62

Closes #214

Example:
  has_attached_file :image,
    :bucket => "testing",
    :path => ":attachment/:style/:basename.:extension"
    :s3_permissions => {
      :original => :private
    },
    :styles => {
      :thumb => '80x80>'
    }

The above will allow public read access on :thumb but require credentials for :original.

Example of setting default to private:
  has_attached_file :image,
    :bucket => "testing",
    :path => ":attachment/:style/:basename.:extension"
    :s3_permissions => :private
    :styles => {
      :thumb => '80x80>'
    }

The above will set all to private

Closes #398

Closes #499

the :default_url option for has_attached_file can now also be a Proc/lamba, which gets executed *before* it gets interpolated

Closes #253, Closes #360

There's a case when you really don't want to make a thumbnail of only the first frame, such as making thumbnail for GIF image. This patch will check that the source and output format is an animated format, and not calling `[0]` on it.

Closes #454

Change S3 storage behavior to get the content_type for each upload, rather than only the original file. This prevents a still frame from a video or a conversion of a file from being served with the original mimetype.

Closes #38, #129

`convert` will pick this up automatically. :)
