gm is a JavaScript image processing library and Node.js manipulation tool that serves as a programmatic wrapper for the GraphicsMagick engine. It translates JavaScript method calls into shell commands to automate the resizing, cropping, and transformation of images. The library provides an interface to execute specific GraphicsMagick operations while allowing raw command passthrough for custom arguments or engine features not covered by the standard API. Its capabilities cover geometric manipulation, color and tone adjustment, and image quality optimization. It includes tools for image compo

AlamofireImage is an image downloading and caching library designed as an extension for Alamofire. It provides a serialization framework to convert network responses into image objects and a memory-based caching system to reduce redundant network requests. The project features a variant-aware asynchronous cache that stores both original images and their filtered versions separately. It includes tools for animating the replacement of placeholder images with downloaded content through various transition effects. The library covers image acquisition through parallel downloading and prioritized

lightmapper.h is a C/C++ single-file library for lightmap baking by using your existing OpenGL renderer.

A C/C++ single-file library that minimizes the hard transition errors of disjoint edges in lightmaps. It is based on a idea presented by Michał Iwanicki in the talk Lighting Technology of "The Last Of Us". A least squares solver is used to find a minimal error solution to the problem of sampling…

Bild is an image processing library implemented in the Go programming language. It provides a collection of algorithmic engines for image manipulation, including a convolution kernel engine for filtering, an image blending tool for layer composition, and a procedural noise generator for creating synthetic textures. The project is distinguished by its procedural generation capabilities, implementing Perlin, Gaussian, binary, and uniform noise algorithms to produce random pixel distributions and organic patterns. It also features a command-line interface that allows users to apply visual effect

Asciinema is a platform for capturing, replaying, and sharing command-line sessions. It provides a comprehensive suite of tools to record terminal activity into lightweight, text-based files that preserve ANSI escape sequences, allowing users to document technical workflows, troubleshooting steps, and software demonstrations with high fidelity. The project distinguishes itself through its versatile playback and distribution capabilities. It features a web-based player that renders interactive terminal sessions directly in the browser, supporting features like seeking, playback speed control,

Package aseprite implements a decoder for Aseprite sprite files (.ase and .aseprite files).

Assimp is a cross-platform 3D asset pipeline and import library that loads numerous industry-standard 3D file formats into a single unified internal data structure. It functions as a framework for converting 3D models between different file formats across multiple operating systems and architectures. The project provides a 3D mesh processing tool for normalizing and optimizing geometry through triangulation, vertex removal, and normal generation. It also includes a 3D asset export utility to write internal scene data back into various external file formats. The system covers broad capability
