imgp - Multi-core batch image resizer and rotator

  •        28

imgp is a command line image resizer and rotator for JPEG and PNG images. It can resize (or thumbnail) and rotate thousands of images in a go, at lightning speed, while saving significantly on storage. Powered by multiprocessing, an intelligent adaptive algorithm, recursive operations, shell completion scripts, EXIF preservation (and more), imgp is a very flexible utility with well-documented easy to use options.

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).

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

  •    Go

Small Go package for fast high-level image processing using libvips via C bindings, providing a simple, elegant and fluent programmatic API.bimg was designed to be a small and efficient library supporting a common set of image operations such as crop, resize, rotate, zoom or watermark. It can read JPEG, PNG, WEBP natively, and optionally TIFF, PDF, GIF and SVG formats if libvips@8.3+ is compiled with proper library bindings.

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.

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.

This project was recently updated to 2.0 and is PSR-0 compliant and supports Composer integration. Some parts of the documentation are incorrect as they haven't been updated for the new version. Your 1.0 code is not compatible with 2.0! Please review the updated examples for how to use the new version. PHP Thumb is a light-weight image manipulation library aimed at thumbnail generation. It features the ability to resize by width, height, and percentage, create custom crops, or square crops from the center, and rotate the image. You can also easily add custom functionality to the library through plugins. It also features the ability to perform multiple manipulations per instance (also known as chaining), without the need to save and re-initialize the class with every manipulation.

imbo - Imbo is an image "server" that can be used to add/get/delete images using a RESTful interface

  •    PHP

Imbo is an image "server" that can be used to add/get/delete images using a REST interface. There is also support for adding meta data to an image. The main idea behind Imbo is to have a place to store high quality original images and to use the REST interface to fetch variations of those images. Imbo will resize, rotate, crop (amongst other features) on the fly so you won't have to store all the different variations. End-user docs can be found here.
