Technical interviews can be difficult to do well. The script presented there works fine, but evidently duplicates the photos included in the GIF, which resulted in a much larger GIF file.News & Announcements An interview process to learn from - ImageMagick Lessons and ATS contributions This post is based on Jacob Samela’s post here. Command + click all of the photos you want as part of your GIF, right click and go to Services > Make Animated Gif. Snap a few photos with Facetime, or just test with whatever you have. Once you’re happy with it, go to File > Save and name this workflow “Make Animated Gif”. Please note that if you make more than one gif, it will automatically override the file that is there unless you rename it to something other than animated.gif. Totally up to you! Feel free to change the output path of the file from ~/Desktop/animated.gif to whatever you like. I like 30-35, but sometimes it makes sense to go as low as 20.
#Imagemagick make gif series
The -delay flag simply denotes how long each image in the series is displayed for, in milliseconds. Then select “Service” and press the “Choose” button on the bottom right-hand corner.Ī new dialog appears that reads “ Service receives selected dropdown menu and instead choose “ as arguments“.Ĭopy and paste the following command in the text area: /usr/local/bin/convert -delay 35 -loop 0 " ~/Desktop/animated.gif Then go to the top menu bar where it reads File and click on “New”. If a window pops up asking you to select a file, just press “Done”. Open up Automator by going to Applications > Automator.app.
#Imagemagick make gif install
That is what we need in order to create the GIF service: brew install imagemagick 3. Imagemagick is a very powerful tool for working with images, but it also comes with a convenient tool called convert. If your system is ready to brew, continue to step #2. Execute the following command to get Homebrew installed: ruby -e " $( curl -fsSL )" Open up Terminal by going to Applications > Utilities > Terminal.app. So, if you don’t already have Homebrew installed, let’s do that first. If you normally use MacPorts, Fink, or are just compiling things manually, feel free to use that instead. Of course, this behavior can be overwritten, but that’s a topic for another day.
It’s very easy to use and, by default, it attempts to use existing libraries that come built within the operating system first (usually, anyway). One of the biggest advantages of using Homebrew is that you don’t have to be an administrator to use it.
If it comes down to you having to choose between a Homebrew formula or a DMG (disk image) file to install something, definitely stick with Homebrew for your own future sanity.
Homebrew is a convenient (and arguably the best) package manager for OS X or macOS, that eases the pain from version management of applications and libraries. For my own personal amusement I’ll be using the following photos I randomly snapped of myself eating cheese and crackers: There are many ways to generate your own animated GIFs, but I personally prefer to use a shell script and create my own reusable service instead of, for instance, using a web-based service like Giphy (of course, nothing wrong with that either) where you have to upload photos to a remote server.
#Imagemagick make gif how to
In this brief tutorial I’ll be teaching you how to make a service on macOS (or OS X) that allows you to quickly select multiple images and make them into a GIF file with a single click.
