Types

type Implementation

type Implementation struct {
}

Implementation is the specific Implementation of the hashing service

func Create

func Create() Implementation

Create creates a new instance of the hashing service

func (Implementation) Distance

func (imp Implementation) Distance(h1 imhash_interfaces.PerceptualHash, h2 imhash_interfaces.PerceptualHash) (imhash_interfaces.HammingDistance, error)

Distance calculates the hamming distance between two hashes

func (Implementation) GetHandle

func (imp Implementation) GetHandle() string

func (Implementation) HashFromPath

func (imp Implementation) HashFromPath(path string) (imhash_interfaces.PerceptualHash, error)

HashFromPath creates a hash from an image file at the given path

func (Implementation) HashFromString

func (imp Implementation) HashFromString(hashAsString string) (imhash_interfaces.PerceptualHash, error)

HashFromString recreates a hash from a hash string use it to recreate a hash from a stored value
