Usage

Bundled tool

> AC_APIKEY=abcdef-123445 gif2cast animated.gif
or
> gif2cast -o out.cast animated.gif

Library

fp, err := os.Open(fileName)
...
gifImage, err := gif.DecodeAll(fp)
...
width := 80
height := 24
gc := gif2cast.NewGif2Cast(gifImage, 80, 24, "title")
out, err := os.OpenFile(outFilename, os.O_CREATE|os.O_TRUNC|os.O_WRONLY, 0666)
gc.Write(out)
//or
url, err := gc.Upload(APIKEY)
if err != nil {
    fmt.Println("Cannot upload:", err)
    os.Exit(1)
}
fmt.Println(url)

Note

This library is some hobby project I wrote over the weekend so it has a lot of rough edges, e.g.

• No support on partial frame refresh, it takes every frame in the gif as a full refresh.
• Does not support disposal methods
• Does not support loop
• Bundled tool does not find API automatically
• Rudimentary optimization to reduce asciicast file size
