    I develop iOS apps at LINE Fukuoka.

    Great to meet you all. This is ha1f from LINE Fukuoka, I develop iOS apps at LINE. Back when I was as a part timer at LINE, I was involved in making in-house tools for LINE. To share a little bit of my background, I was hired as a part timer with a confirmed offer to a full time position. Anyway, today, I'd like to show you a tool I developed during my time as a part timer, the Animation Sticker Checker.

    What is APNG?

    Before we get into the details of the tool, let's discover what APNG is. APNG (Animated Portable Network Graphics) is a specification for animated image, consisting of images each numbered with a sequence number. LINE animation stickers use APNG. Unlike GIF, APNG supports full color, alpha channel and has a high compression rate. APNG is compatible with PNG, and is displayed as a still image for image viewers that do not support APNG. If you have the right tool, you can convert a sequence of PNG files into an APNG file.
