I learned many new techniques and tools today, but they may not be the most relevant for my job but they were certainly fun to work on. I just animated my first slack emoji today, and learned a ton in the process. If you too would like to be the rockstar on your slack channel, buckle in and I will teach you how to do your own emoji. First off you will need a photo editor, because I didn’t want to buy anything and it is an awesome piece of software, I went with GIMP.
For slack, the best emoji size is 128×128 pixels. So open a new image that is 128×128, next you can add a background image you like or text. I create a squee emoji that had scrolling text in it, so I went with a white background with scrolling magenta text. As you can see, this was a huge gap in my companies custom emoji’s and needed to remedied asap.
From there decide what you want it to do. I went with scrolling because that seemed easy. Each of your layers is a different part of animation. So with scrolling, each layer moves it slightly to the left. You could do confetti or colors and then each of the layers is the movement. To check what it looks like, go to Filters > Animation > Playback … This will show you what your animation will be. Once you are happy with the look then use Filter > Animation > Optimize (for GIF) and then export as a GIF image. For more detailed instruction check out this awesome tutorial from GIMP.org . Now you are ready to upload it and use on slack, if you need some help in that department, check out Slack’s help guide.
