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.

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.

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.

imgp - Multi-core batch image resizer and rotator

•    Python

---

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.

halfshell - A proxy server for processing images on the fly.

•    Go

---

Halfshell is a proxy server for processing images on the fly. It allows you to dynamically resize (and apply effects to) images hosted on S3, a local filesystem or an http source via query parameters. It supports creating “families” of images which can read from distinct image sources and enable different configuration values for image processing and retrieval. See the introduction blog post. Halfshell was architected to be extensible from the beginning. The system is composed of a few components with their own configuration and simple interfaces.

image-resizer - On-the-fly image resizing using Node.js and GraphicsMagick. Heroku Ready!

•    Javascript

---

image-resizer is a Node.js application that sits as a custom origin to your CDN and will resize/optimise images on-the-fly. It is Heroku ready, but can also be deployed easily to any cloud provider (has been used with success on AWS). The primary goal for this project was to abstract the need to set image dimensions during the upload and storage phase of images in a modern web application.

govips - A fast and robust image library for Go built on libvips

•    Go

---

This package wraps the core functionality of libvips image processing library by exposing all image operations on first-class types in Go. Additionally, it exposes raw access to call operations directly, for forward compatibility. This library was inspired primarily based on the C++ wrapper in libvips.

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).
