JavaScript Image Manipulation Program (Jimp) allows you to easily manipulate and transform your images into any required format, style, or dimension. It also optimizes images for minimal file size, ensures high visual quality for an improved user experience, and reduces bandwidth Processing allows working with different media and can be used to create animations, data-visualisations and digital art, but also for image manipulation. Processing.js lets you write Processing code and simply include it in your website by applying it to a canvas element JIMP stands for Javascript Image Manipulation Program. It is a Node module for image manipulation or processing which is written entirely in Javascript Language. No external dependencies is used to make it

Output images can be in JPEG, PNG, WebP, and TIFF formats as well as uncompressed raw pixel data. Streams, Buffer objects and the filesystem can be used for input and output. A single input Stream can be split into multiple processing pipelines and output Streams In this video, I will be showing you the powerful library Sharp for image manipulation in Node.js Subscribe for more https://www.youtube.com/channel/UCMA8g.. The typical use case for this high speed Node.js module is to convert large images in common formats to smaller, web-friendly JPEG, PNG, AVIF and WebP images of varying dimensions. Resizing an image is typically 4x-5x faster than using the quickest ImageMagick and GraphicsMagick settings due to its use of libvips

An image processing library for Node written entirely in JavaScript, with zero native dependencies Get encoded binary image data as a NodeJS Buffer. When opening an image, it is decoded and stored in memory as an uncompressed image. All manipulations are done on the uncompressed data in memory. This method allows to encode the image to one of the specified formats and get the encoded data as a NodeJS Buffer object Eyal Arubas talks about why he was dissatisfied with existing image processing Node.js modules and presents how he went about building his own alternative so..
