JavaScript Image Manipulation Program (JIMP) adapted to Gulp
Manipulate your images directly from Gulp, without the need for any external dependency (i.e. external executables). OS independent.
$ npm install --save-dev gulp-jimpvar gulp = require('gulp');
var jimp = require('gulp-jimp');
gulp.task('default', function () {
return gulp.src('src/images/*')
.pipe(jimp({ resize: { width: 200, height: 300 }, scale: 30, greyscale: true }))
.pipe(gulp.dest('dist'));
});Support all Jimp functionalities as of version 0.2.9.
You can define the transformations in the options, and add as many as you want (see example above).
{ resize: { width: 100, height: 100 } } // Very quick, unlike "crop"{ crop: { x: 100, y: 100, width: 200, height: 200 } } // Very slow for some reason{ invert: true } // Inverts the colours (very fast){ greyscale: true } // Turns into gray scale (very fast){ sepia: true } // Turns into sepia (very fast){ opacity: 0.5 } // Between 0 and 1, but doesn't seem to work{ scale: 1.2 } // Will increase the image size by 20%{ blur: 10 } // Value between 1 (slighly blured) and 100 (completely blured){ gaussian: 90 } // Min value: 1 (very very slow, even at 1, even slower when you go higher)Thanks to Oliver Moran and his wonderful Jimp module
I'm planning to take a look at the original Jimp module, to see if I can make that use streams/buffers to avoid having to write a temporary file.
