var DefaultEncodings = []Encoding{
	&RawEncoding{},
	&TightEncoding{},
	&TightPNGEncoding{},
}

DefaultEncodings lists the encodings enabled by default on the server.

Types

type Encoding

type Encoding interface {
	// Code should return the int32 code of the encoding type.
	Code() int32
	// HandleBuffer should craft a rectangle from the given image and
	// queue it onto the given writer.
	HandleBuffer(w io.Writer, format *types.PixelFormat, img *image.RGBA)
}

Encoding is an interface to be implemented by different encoding handlers.

func GetDefaults

func GetDefaults() []Encoding

GetDefaults returns a slice of the default encoding handlers.

type RawEncoding

type RawEncoding struct{}
