Functions

func HalfBlock

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

HalfBlock renders img using Unicode half-block characters (▀ U+2580). Each character cell encodes two vertically stacked pixels using foreground (top) and background (bottom) ANSI 24-bit color. Works on any terminal with UTF-8 and truecolor support.

func Kitty

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

Kitty encodes img and writes a Kitty graphics protocol sequence to w. The image is re-encoded as PNG (Kitty format f=100) and chunked.

func Sixel

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

Sixel encodes img as a DEC Sixel sequence and writes it to w. Colors are quantized to 256 using a fast median-cut algorithm.
