• Variables
• func Decode(r io.Reader) (image.Image, error)
• func DecodeConfig(r io.Reader) (image.Config, error)
• func Encode(w io.Writer, m image.Image) error

Variables

var ErrUnsupported = errors.New("bmp: unsupported BMP image")

ErrUnsupported means that the input BMP image uses a valid but unsupported feature.

Functions

func Decode

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

Decode reads a BMP image from r and returns it as an image.Image. Limitation: The file must be 8, 24 or 32 bits per pixel.

func DecodeConfig

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

DecodeConfig returns the color model and dimensions of a BMP image without decoding the entire image. Limitation: The file must be 8, 24 or 32 bits per pixel.

func Encode

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

Encode writes the image m to w in BMP format.
