Gifsicle -resize 300x200 -i animation.gif > animation-clipped.gif Gifsicle -resize-fit-height 100 -i animation.gif > animation-100px.gif To do this, we’ll need to add the -crop option: 1. Of course, that’s just going to give us a Gif that’s 150px tall, but not a 150×150 square. gifsicle -resize 267x150 original.gif > resized.gif. # Scale to a given height with unspecified width With these numbers at hand, we can ask Gifsicle to resize our image to 267×150: 1. Gifsicle -resize-fit-width 300 -i animation.gif > animation-300px.gif With these numbers at hand, we can ask Gifsicle to resize our image to 267×150: 1 gifsicle -resize 267x150 original.gif > resized.gif Of course, that’s just going to give us a Gif that’s 150px tall, but not a 150×150 square. It lets you define a set of default parameters, and extend them for different deployment environments (development, qa, staging, production, etc.). # Scale to a given width with unspecified height Configure your Node.js Applications release notes Introduction Node-config organizes hierarchical configurations for your app deployments. Gifsicle -scale 0.5 -i animation.gif > animation-smaller.gif That's nice but you want to keep the GIF animated, right? Here are a few easy methods for resizing a GIF with gifsicle: If you try to use ImageMagick's basic resize functionality, you'll end up getting the first frame output to the correct size.
#CONFIGURE NODE TO USE GIFSICLE HOW TO#
I showed you how to merge and optimize animated GIFs with gifsicle, and now let's look at resizing animated GIFs. My favorite image manipulation utility, ImageMagick, doesn't seem to be the best utility for animated GIFs - another utility called gifsicle is as good as it gets.
Replace input.gif and output.gif with the input and output file names, and 99 with the number of frames in your animation. Using -flag without specifying any value will set the value to true.
A -argument tells the cli parser to stop reading flags. Putting -foo bar on the command line sets the foo configuration parameter to 'bar'. GIFs are kind of a video file, because they have frames, but there's no real control over how they play or loop. Here's a simpler solution using gifsicle than JohnB's script: gifsicle -U input.gif seq -f 'g' 0 2 99 -O2 -o output.gif This command should work in most Unix shells I've tested it in bash. npm gets its configuration values from the following sources, sorted by priority: Command Line Flags. Animated GIFs are images but you can't really handle them link other types of images, like PNGs or JPEGs or even WebPs.
