Types

type Encoder

type Encoder interface {
	// retrieves the vis which is to be encoded within the handshake
	Vis() uint8
	// retrieves the standard resolution for this transmission format
	// while this width and height is typically not required for successful encoding, it is
	// recommended to stick to them as most decoders will expect the standard sizes
	Resolution() image.Rectangle
	// encodes a given image into an SSTV audio signal represented by an array of raw PCM samples
	Encode(image image.Image) *audio.FloatBuffer
}
