Advanced tools
Package description
The gifsicle npm package is a Node.js wrapper for the Gifsicle command-line tool, which is used for manipulating GIF images. It allows you to optimize, resize, and edit GIFs programmatically.
Optimize GIF
This feature allows you to optimize a GIF file to reduce its size. The code sample demonstrates how to use the gifsicle package to optimize an input GIF and save the optimized version as output.gif.
const gifsicle = require('gifsicle');
const execFile = require('child_process').execFile;
execFile(gifsicle, ['--optimize', '--output', 'output.gif', 'input.gif'], (err) => {
if (err) throw err;
console.log('GIF optimized');
});Resize GIF
This feature allows you to resize a GIF to specified dimensions. The code sample demonstrates how to resize an input GIF to 200x200 pixels and save the resized version as output.gif.
const gifsicle = require('gifsicle');
const execFile = require('child_process').execFile;
execFile(gifsicle, ['--resize', '200x200', '--output', 'output.gif', 'input.gif'], (err) => {
if (err) throw err;
console.log('GIF resized');
});Extract Frames
This feature allows you to extract individual frames from a GIF. The code sample demonstrates how to extract frames from an input GIF, which will be saved as separate files.
const gifsicle = require('gifsicle');
const execFile = require('child_process').execFile;
execFile(gifsicle, ['--explode', 'input.gif'], (err) => {
if (err) throw err;
console.log('Frames extracted');
});The gifencoder package is used for creating GIFs from a series of images or canvas frames. Unlike gifsicle, which focuses on optimizing and editing existing GIFs, gifencoder is more suited for generating new GIFs programmatically.
The gif-frames package allows you to extract frames from a GIF as images. While gifsicle can also extract frames, gif-frames provides more control over the extraction process, such as selecting specific frames or ranges.
The sharp package is a high-performance image processing library that supports multiple image formats, including GIF. It can resize, crop, and manipulate images, but it is more general-purpose compared to gifsicle, which is specialized for GIFs.
Readme
gifsicle manipulates GIF image files in many different ways. Depending on command line options, it can merge several GIFs into a GIF animation; explode an animation into its component frames; change individual frames in an animation; turn interlacing on and off; add transparency and much more.
$ npm install --save gifsicle
var execFile = require('child_process').execFile;
var gifsicle = require('gifsicle');
execFile(gifsicle, ['-o', 'output.gif', 'input.gif'], function (err) {
console.log('Image minified!');
});
$ npm install --global gifsicle
