Make sure GraphicsMagick or ImageMagick is installed on your system and properly set up in your PATH.

npm install -save-dev gulp-image-resize GraphicsMagick or ImageMagick. Override the output format of the processed file. Resizing images made easy - thanks to GraphicsMagick or ImageMagick. The good news is that Gulp streams all things, a Gulp plugin can be used in any Node.js program without modification.
However, Gulp is a command-line build tool, what I wanted was to process images as they were uploaded. WebP lossless images are up to 26 smaller in size compared to PNGs and WebP lossy images are 25-34 smaller in size compared to JPEGs. I have been using Gulp to automate image minification and resizing on my local machine with great success. Ranges from 0 (really bad) to 1 (almost lossless). WebP is a recent image format that offers lossless and lossy compression for images on the web. Remember that gulp starts all tasks in parallel, so do not run this task with too many images. As the module names say, gulp-image-resize resizes images and gulp-imagemin optimizes image size. In other not to process image that is already processed, I use gulp-changed. options.qualityĭetermines the output quality of the resized image. Because I was already using Gulp for JavaScript and SCSS, choice was obvious. Doesn't have any effect, if options.crop is false. When cropping images this sets the image gravity. Node. jpg ), resize them to 300 pixels wide and then save them in the output directory. gulp-image-resize: resize images using ImageMagick. globby: match files and folders using globs and expose a Promise API. deleteEmpty: delete empty folders recursively. This says that we want ImageMagick’s mogrify function to take all JPEG files in the current directory (. Apart from Gulp itself, we will need a few packages to accomplish this: del: delete files and folders. Possible values: NorthWest, North, NorthEast, West, Center, East, SouthWest, South, SouthEast Using mogrify is similar, but with the syntax reordered a bit: mogrify -path output/ -resize 300. options.cropĭetermines whether images will be cropped after resizing to exactly match options.width and options.height. If set to false (default), image will be copied instead of resized if it would be upscaled by resizing. options.upscaleĭetermines whether images will be upscaled. Making images responsive and declined for differents format becomes simple because we only have to configure it and the rest is done automatically for us. options.heightĭefault value: 0 (only if width is defined)Ī number pixel value that is the target height. gulp-sharp-responsive is based on the Sharp NPM package, a fast image processing library, and aims to simplify this tedious task. task ( 'default', function ( ) ) API imageResize(options) options.widthĭefault value: 0 (only if height is defined)Ī number pixel value that is the target width. Var gulp = require ( 'gulp' ) var imageResize = require ( 'gulp-image-resize' ) gulp.
