Glide is an image loading and caching library for Android that fetches and decodes images, GIFs, and video stills from local or remote sources. It functions as a media rendering framework and memory management tool designed to resize and downsample assets to fit specific view dimensions. The system prioritizes scrolling performance through a multi-level caching strategy that stores decoded media in memory and raw data on disk. It employs resource pooling to reuse bitmap memory and binds image loading tasks to component lifecycles to automatically release resources and prevent memory leaks. T

Coil is an image loading and caching pipeline designed for Android and Compose Multiplatform applications. It functions as a comprehensive loader, caching engine, and rendering utility that asynchronously fetches and displays images from network URLs, local storage, and multiplatform resource systems. The library distinguishes itself through a flexible fetcher-decoder pipeline and an interface-driven component registry, allowing for the integration of custom networking clients and decoders. It provides specialized support for rendering scalable vector graphics, animated formats such as GIF an

SimpleCov is a Ruby code coverage tool and analysis engine used to track which lines, branches, and methods of code execute during tests. It functions as a coverage threshold enforcer and test suite aggregator, recording execution data to identify untested areas of an application. The tool distinguishes itself through the ability to merge coverage results from parallel worker processes and subprocesses into a single unified report. It supports baseline comparison to detect coverage regressions and can gather data from code executed via dynamic evaluation methods, such as those used in templat

:woman: Library for image processing

C++ library thats implemets class color. Available models: RGB, HSL, HSV, CMY, CMYK, YIQ, YUV and growing.

Makes dealing with images buttery smooth.

The CImg Library is a small and open-source C++ toolkit for image processing

Pundit is a Ruby authorization framework that implements policy-based access control. It maps domain models to dedicated logic classes that determine whether a user is permitted to perform specific actions on data objects. The framework utilizes plain Ruby objects to decouple authorization logic from the model. It includes mechanisms for data query scoping to filter record collections based on user permissions, as well as attribute-level permission control to restrict which specific model fields a user can modify. The system provides tools for authorization coverage verification to ensure se

Fast Caching for Objective-C (iPhone & Mac Compatible)

EventMachine is a reactor-pattern network framework for Ruby that provides an asynchronous I/O library for performing non-blocking network and file operations. It functions as a network server framework used to build scalable TCP and UDP servers and clients that process multiple simultaneous requests. The framework implements a concurrency model that dispatches network events to registered handlers using a single-threaded event loop. This approach allows for the management of high-concurrency network connections without the overhead of multi-threaded programming. The library covers the devel

Fresco is an Android image loading library and cache manager designed to fetch, decode, and display images from network or local sources. It functions as a rendering engine for animated image formats and a streaming system for progressive image loading. The library distinguishes itself through specialized memory management that utilizes off-heap allocation to reduce garbage collection overhead and prevent out-of-memory errors. It includes a dedicated rendering pipeline for animated GIFs and WebP files and supports progressive JPEG decoding to render low-resolution versions of images while the

Cropper is a JavaScript image cropping library and HTML5 canvas image editor. It serves as a web-based image manipulation tool that allows users to visually select and trim specific areas of an image directly within a browser. The library provides a visual interface for defining precise crop areas with configurable aspect ratios and zoom controls. It includes tools to rotate, scale, and zoom images to align subjects before exporting the final result. The tool handles browser-based image processing by generating a canvas element from a selected image area for use or download. It manages crop

Markup is a tool for converting various documentation formats and manual pages into structured HTML. It functions as a rendering engine selector and converter that transforms raw markup files into web-ready output using a pluggable pipeline. The system identifies the appropriate rendering engine by utilizing file extensions or analyzing document content through pattern-based language detection. This allows the pipeline to handle documents where file extensions are missing or ambiguous. The project covers a broad range of content transformation, including the conversion of traditional man pag

A statesmanlike state machine library.

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
