ImageMagick

•    C++

---

ImageMagick is a software suite to create, edit, and compose bitmap images. It can read, convert and write images in a variety of formats (over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF. Use ImageMagick to translate, flip, mirror, rotate, scale, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.

imaging - Simple Go image processing package

•    Go

---

Package imaging provides basic image manipulation functions (resize, rotate, flip, crop, etc.). This package is based on the standard Go image package and works best along with it.Image manipulation functions provided by the package take any image type that implements image.Image interface as an input, and return a new image of *image.NRGBA type (32bit RGBA colors, not premultiplied by alpha).

menyoki - Screen{shot,cast} and perform ImageOps on the command line 🌱 🏞️

•    Rust

---

menyoki is a screencast and screenshot utility that can also perform various image related operations such as making/splitting GIFs and modifying/analyzing image files. It aims to be a lightweight command line tool for either helping out on day-to-day life operations or complicated detail-centric issues. Originally it was designed to record/screenshot terminal windows but it can be tweaked easily for other purposes with command line arguments, environment variables, or a configuration file. menyoki requires a window system implementation of the supported platform for record and capture actions. Other features are expected to work normally since they don't require a window system running (or grabbing a window to operate on). For example, despite the macOS is not listed as a supported platform, menyoki still can perform image operations such as edit and analyze if it's compiled on macOS.

Crunch - Insane(ly slow but wicked good) PNG image optimization

•    Python

---

Crunch is a tool for lossy PNG image file optimization. It combines selective bit depth, color type, and color palette reduction with zopfli DEFLATE compression algorithm encoding using the pngquant and zopflipng PNG optimization tools. This approach leads to a significant file size gain relative to lossless approaches at the expense of a relatively modest decrease in image quality (see example images below). Historical benchmarks with the files included in Cédric Louvrier's PNG Test Corpus versus other commonly used PNG optimization software are available in BENCHMARKS.md.

Flyimg - Microservice to resize and crop images on the fly

•    PHP

---

Image resizing, cropping and compression on the fly with the impressive MozJPEG compression algorithm. One Docker container to build your own Cloudinary-like service.You pass the image URL and a set of keys with options, like size or compression. Flyimg will fetch the image, convert it, store it, cache it and serve it. The next time the request comes, it will serve the cached version.

google-images-download - Python Script to download hundreds of images from 'Google Images'

•    Python

---

This is a command line python program to search keywords/key-phrases on Google Images and optionally download images to your computer. You can also invoke this script from another python file. This is a small and ready-to-run program. No dependencies are required to be installed if you would only want to download up to 100 images per keyword. If you would want more than 100 images per keyword, then you would need to install Selenium library along with chromedriver. Detailed instructions in the troubleshooting section.

laravel-image - Image manipulation library for Laravel 4 and 5 based on Imagine (https://github

•    PHP

---

Laravel Image is an image manipulation package for Laravel 4 and 5 based on the PHP Imagine library. It is inspired by Croppa as it can use specially formatted urls to do the manipulations. It supports basic image manipulations such as resize, crop, rotation and flip. It also supports effects such as negative, grayscale, gamma, colorize and blur. You can also define custom filters for greater flexibility. The main difference between this package and other image manipulation libraries is that you can use parameters directly in the url to manipulate the image. A manipulated version of the image is then saved in the same path as the original image, creating a static version of the file and bypassing PHP for all future requests.

ImageScript - zero-dependency JavaScript image manipulation

•    Javascript

---

ImageScript is a zero-dependency alternative to common JavaScript bitmap image manipulation tools. It can achieve much more performant results by utilizing lower-level memory access, less memory copying and WebAssembly / native binaries for decoding and encoding. If you have any additional questions, feel free to join the discord support server.

imgmin - Lossy image optimization

•    C

---

Image files constitute a majority of static web traffic.[17] Unlike text-based web file formats, binary image files do not benefit from built-in webserver-based HTTP gzip compression. imgmin offers an automated means for enforcing image quality as a standalone tool and as a webserver module. imgmin determines the optimal balance of image quality and filesize, often greatly reducing image size while retaining quality for casual use, which translates into more efficient use of storage and network bandwidth, which saves money and improves user experience. Websites are composed of several standard components. Most (HTML, CSS, Javascript, JSON, XML, etc) are text-based. They can be efficiently compressed for transfer via gzip, supported by all mainstream webservers and browsers. But image and video files are binary, non-text files, and generally are not worth auto-compressing in the webserver.
