...Colour spaces, embedded ICC profiles and alpha transparency channels are all handled correctly. Lanczos resampling ensures quality is not sacrificed for speed. As well as image resizing, operations such as rotation, extraction, compositing and gamma correction are available. Most modern macOS, Windows and Linux systems running Node.js v10+ do not require any additional install or runtime dependencies. This module supports reading JPEG, PNG, WebP, AVIF, TIFF, GIF and SVG images. Output images can be in JPEG, PNG, WebP, AVIF and TIFF formats as well as uncompressed raw pixel data. ...

ImageMagick® is a free and open-source software suite for displaying, converting, and editing raster image and vector image files. It can read and write over 200 image file formats, and can support a wide range of image manipulation operations, such as resizing, cropping, and color correction. ImageMagick is written in C and is available for a wide range of operating systems, including Linux, macOS, and Windows. It can be used as a standalone application, or as a library that can be...

QuadRay engine is a realtime raytracing project aimed at full SIMD utilization on ARM, MIPS, POWER and x86 architectures. The efficient use of SIMD is achieved by processing four rays at a time to match SIMD register width (hence the name). The rendering core of the engine is written in a unified SIMD assembler allowing single assembler code to be compatible with different processor architectures, thus reducing the need to maintain multiple parallel versions. At present, Intel...

JHotDraw is a two-dimensional graphics framework for structured drawing editors that is written in Java. It is based on Erich Gamma's JHotDraw, which is copyright 1996, 1997 by IFA Informatik and Erich Gamma.

...ACM Transactions on Graphics (presented at SIGGRAPH 2018) Exposure is originally designed for RAW photos, which assumes 12+ bit color depth and linear "RGB" color space (or whatever we get after demosaicing). jpg and png images typically have only 8-bit color depth (except 16-bit pngs) and the lack of information (dynamic range/activation resolution) may lead to suboptimal results such as posterization. Moreover, jpg and most pngs assume an sRGB color space, which contains a roughly 1/2.2 Gamma correction, making the data distribution different from training images (which are linear). Exposure is just a prototype (proof-of-concept) of our latest research, and there are definitely a lot of engineering efforts required to make it suitable for a real product.

Guetzli is a JPEG encoder that aims for excellent compression density at high visual quality. Guetzli-generated images are typically 20-30% smaller than images of equivalent quality generated by libjpeg. Guetzli generates only sequential (nonprogressive) JPEGs due to faster decompression speeds they offer. Get a copy of the source code, either by cloning this repository, or by downloading an archive and unpacking it. Install libpng. If using your operating system package manager, install...

Image Tools is a screen capture, file sharing and image processing tool. It features multi-threaded batch image resizing, conversion, cropping, flipping/rotating, watermarks, decolorizing (grayscale, negative, sepia), and optimizing. The BMP, GIF, TIFF, JPEG, PNG, and EMF image types are supported. It is compatible with Linux MONO (only for GNOME and Xfce). Multicore processing is supported to increase performance. The quality for output when optimizing is variable. Color channels can be...
