Functions ¶

func Decode ¶

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

Decode reads a Targa image from r and returns it as an image.Image. The type of Image returned depends on the Targa contents.

func DecodeConfig ¶

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

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