Sharp - High performance Node.js image processing

•    Javascript

---

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 and WebP images of varying dimensions.Resizing an image is typically 4x-5x faster than using the quickest ImageMagick and GraphicsMagick settings.

image_processing - High-level image processing wrapper for libvips and ImageMagick/GraphicsMagick

•    Ruby

---

Provides higher-level image processing helpers that are commonly needed when handling image uploads. This gem can process images with either ImageMagick/GraphicsMagick or libvips libraries. ImageMagick is a good default choice, especially if you are migrating from another gem or library that uses ImageMagick. Libvips is a newer library that can process images very rapidly (often multiple times faster than ImageMagick).

GraphicsMagick

•    C++

---

GraphicsMagick is the swiss army knife of image processing. It provides a robust and efficient collection of tools and libraries which support reading, writing, and manipulating an image in over 88 major formats including important formats like DPX, GIF, JPEG, JPEG-2000, PNG, PDF, PNM, and TIFF.

vips - Go Bindings for Vips (a super fast image processor)

•    Go

---

This package is powered by the blazingly fast libvips image processing library, originally created in 1989 at Birkbeck College and currently maintained by JohnCupitt. The typical use case for this high speed package is to convert large images of many formats to smaller, web-friendly JPEG, PNG images of varying dimensions.

ImageMagick - ImageMagick 7

•    C

---

Use ImageMagick® o create, edit, compose, or convert bitmap images. It can read and write images in a variety of formats (over 200) including PNG, JPEG, GIF, HEIC, TIFF, DPX, EXR, WebP, Postscript, PDF, and SVG. Use ImageMagick to resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves. The functionality of ImageMagick is typically utilized from the command line or you can use the features from programs written in your favorite programming language. Choose from these interfaces: G2F (Ada), MagickCore (C), MagickWand (C), ChMagick (Ch), ImageMagickObject (COM+), Magick++ (C++), JMagick (Java), L-Magick (Lisp), NMagick (Neko/haXe), MagickNet (.NET), PascalMagick (Pascal), PerlMagick (Perl), MagickWand for PHP (PHP), IMagick (PHP), PythonMagick (Python), magick (R), RMagick (Ruby), or TclMagick (Tcl/TK). With a language interface, use ImageMagick to modify or create images dynamically and automagically.

ImageMagick

•    C++

gulp-responsive - gulp-responsive generates images at different sizes

•    Javascript

---

gulp-responsive depends on sharp. Sharp is one of the fastest Node.js modules for resizing JPEG, PNG, WebP and TIFF images. If you are using Mac OS then before installing gulp-responsive you should install the libvips library. Further information and instructions can be found in the sharp installation guide.

imgproxy - Fast and secure standalone server for resizing and converting remote images

•    Go

---

imgproxy is a fast and secure standalone server for resizing and converting remote images. The main principles of imgproxy are simplicity, speed, and security. imgproxy can be used to provide a fast and secure way to replace all the image resizing code of your web application (like calling ImageMagick or GraphicsMagick, or using libraries), while also being able to resize everything on the fly, fast and easy. imgproxy is also indispensable when handling lots of image resizing, especially when images come from a remote source.

pixterm - Draw images in your ANSI terminal with true color

•    Go

---

PIXterm shows images directly in your terminal, recreating the pixels through a combination of ANSI character background color and the unicode lower half block element. If image has transparency, an optional matte color can be used for background. Also, you can specify a dithering mode; in which case, the image is rendered using block elements with different shades, or using standard ASCII characters in the same way. In dithering mode, the matte color is used to fill the background of the blocks or characters. The conversion process runs fast because it is parallelized in all CPUs.

JPEGView - Image Viewer and Editor

•    C++

---

JPEGView is a small and fast viewer/editor for JPEG, BMP, PNG, WEBP, GIF and TIFF images. On-the-fly image processing is provided - allowing to adjust typical parameters as sharpness, color balance, contrast and local under-/overexposure.

image-size - Node module for detecting image dimensions

•    TypeScript

---

NOTE: The asynchronous version doesn't work if the input is a Buffer. Use synchronous version instead. If the target file is an icon (.ico) or a cursor (.cur), the width and height will be the ones of the first found image.

ruby-vips - Ruby extension for the libvips image processing library.

•    Ruby

---

This gem provides a Ruby binding for the libvips image processing library. Programs that use ruby-vips don't manipulate images directly, instead they create pipelines of image processing operations building on a source image. When the end of the pipe is connected to a destination, the whole pipeline executes at once, streaming the image in parallel from source to destination a section at a time.
