256 colour terminal support

[jai-x]

This music player is really cool, although I am missing out on the album art feature due to not having a true colour terminal available.

Could there be an option such that the colours used in the album art display be approximated to within the 256 colour range?

Hi, I'll give it a go when I'm free. Although your best bet if you really want to use it (and know some Go) is to look into ansimage/ansimage.go and manually tweak it so that you approximate the true RGB values. I won't be changing this file much, so it is safe (for the foreseeable future) to mess about with it in your fork. Line 88 is where you should modify:

// Render returns the ANSI-compatible string form of ANSI-pixel.
func (ap *ANSIpixel) Render() string {
    if ap.upper {
        return fmt.Sprintf(
            "\033[48;2;%d;%d;%dm",
            ap.R, ap.G, ap.B,
        )
    }
    return fmt.Sprintf(
        "\033[38;2;%d;%d;%dm%s",
        ap.R, ap.G, ap.B,
        lowerHalfBlock,
    )
}

PS: In the future I might port orchid to use gdamore/tcell to avoid hacking around termbox so I will change the file, but I don't really have a hard deadline on when I'll do that, if ever.
