Types

type Record

type Record struct {
	Path    string    // idx 0
	ModTime time.Time // idx 1
	Width   int       // idx 2
	Height  int       // idx 3
	// contains filtered or unexported fields
}

func NewRecord

func NewRecord(pattern string, csv ...string) (Record, error)

func NewRecordFields

func New5x5(key []byte) Renderer

New5x5 creates a new 5-by-5 identicon renderer using 'key' as the hash salt

func New7x7

func New7x7(key []byte) Renderer

New7x7 creates a new 7-by-7 identicon renderer using 'key' as the hash salt

func New7x7Size

func New7x7Size(sqSize, maxX, maxY, borderX, borderY int, key []byte) Renderer
