Types ¶

type App ¶

type App struct {
	OutStream, ErrStream io.Writer
}

App consists of output/error streams.

func (*App) Run ¶

func (a *App) Run(args []string) int

Run is the entry point to the cli. Parses the arguments slice and routes to the proper flag/args combination

type Decoder ¶

type Decoder interface {
	Decode(r io.Reader) (image.Image, error)
}

A Decoder reads content from r and decodes it to image.

type DecoderFunc ¶

type DecoderFunc func(r io.Reader) (image.Image, error)

The DecoderFunc type is an adapter to allow the use of ordinary functions as Image decoders. If f is a function with the appropriate signature, DecoderFunc(f) is a Decoder that calls f.

func (DecoderFunc) Decode ¶

func (f DecoderFunc) Decode(r io.Reader) (image.Image, error)

type Encoder ¶

type Encoder interface {
	Encode(w io.Writer, m image.Image) error
}

A Encoder writes image to w.

type EncoderFunc ¶

type EncoderFunc func(w io.Writer, m image.Image) error

The EncoderFunc type is an adapter to allow the use of ordinary functions as Image encoders. If f is a function with the appropriate signature, EncoderFunc(f) is a Encoder that calls f.

func (EncoderFunc) Encode ¶

func (e EncoderFunc) Encode(w io.Writer, m image.Image) error
