Package ppm implements a Portable Pixel Map (PPM) image decoder and encoder. The supported image color model is [color.RGBAModel](https://pkg.go.dev/image/color#RGBAModel).

The PPM specification is at http://netpbm.sourceforge.net/doc/ppm.html.

## func [Decode](reader.go#L28)


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



Decode reads a PPM image from Reader r and returns it as an image.Image.


## func [DecodeConfig](reader.go#L39)


func DecodeConfig(r io.Reader) (image.Config, error)



DecodeConfig returns the color model and dimensions of a PPM image without decoding the entire image.


## func [Encode](writer.go#L15)


func Encode(w io.Writer, img image.Image) error



Encode writes the Image img to Writer w in PPM format.
