class CarrierWave::Blitline::ImageVersion
An instance of an ImageVersion
for Blitline
API.
When the process() version is called in an Uploader class, we store the version name, and the block to create that version as an ImageVersion So, a 'small' image version that's resized to fit 200x200 looks like: ImageVersion.new("small") do process :resize_to_fit => [200, 200] end NOTE: We need a 'default' image version too. This is created automatically, and the name for the version is 'nil'.

Public Instance Methods
primary_function_name()

Returns a String of the name of the primary function for this version
(default: "no_op")
primary_function_params()

Returns a Hash of the params of the primary function for this
version (default: {})

process(function_hash)

Hijacks the process() method that's called within a CarrierWave
uploader.
Example:
version :thumb do process :crop => [10, 10, 200, 200] process :process_to_fill => [500, 500] end This stores the crop function as the "primary" function, and the process_to_fill function as a "secondary" function.
