omggif is a JavaScript implementation of a GIF 89a encoder and decoder.

Python Wrapper to access the Overpass API

Streaming server-side animated (and non-animated) gif generation for node.js

Android ImageView that handles animated GIF images

FLAnimatedImage is a high-performance rendering engine and library for playing animated GIF images on iOS. It functions as an animation engine and image memory manager designed to ensure smooth frame transitions and consistent playback timing across different device environments. The project focuses on maintaining consistent animation speed through variable frame delay support and optimizes rendering efficiency to sustain high frame rates on mobile devices. It includes a memory management system to prevent application crashes and performance degradation during the playback of large or numerou

OSMnx is a Python library for downloading, modeling, and analyzing street networks and other geospatial features from OpenStreetMap. It enables users to retrieve and work with real-world infrastructure data anywhere in the world, providing tools for network analysis, spatial queries, and visualization. The library offers capabilities for working with urban features such as building footprints, transit stops, and elevation data, along with network statistics like intersection density and circuity. It supports multiple travel modes including driving, walking, and biking, and can calculate short

GraphHopper is a Java routing library and OpenStreetMap routing engine used to calculate optimal paths and driving directions. It provides a map matching engine for aligning GPS coordinate traces to road networks, a GTFS transit router for multi-modal travel, and a spatial analysis utility for isochrone generation. The project supports the creation of custom vehicle profiles and weighting logic to influence path calculations. It implements contraction hierarchies to accelerate pathfinding by reducing the search space between coordinates. The engine covers a broad range of geospatial capabili

ChatGPT Java SDK支持流式输出、Gpt插件、联网。支持OpenAI官方所有接口。ChatGPT的Java客户端。OpenAI GPT-3.5-Turb GPT-4 Api Client for Java

OpenAI (and DeepSeek, Azure OpenAI, YandexGPT, Ollama, GigaChat, Qwen) API wrapper for Delphi. Use ChatGPT, DALL-E, Whisper and other products.

gif.js is a JavaScript GIF encoder and client-side color quantizer that generates animated GIF files directly within the web browser. It functions as an HTML5 canvas exporter and image processor, allowing for the creation of animated images from web sources without the need for a backend server. The library utilizes web workers to offload heavy image encoding tasks to background threads, which prevents the browser user interface from freezing during the generation process. This architecture enables the tool to act as a web worker image processor for dynamic image generation. The system cover

High-performance animated GIF support for iOS in Swift

android-gif-drawable is a rendering library for displaying and controlling animated GIF images within Android image views and drawables. It provides a custom drawable implementation for frame-based animations, a playback system for seeking and looping, and a metadata extractor for retrieving technical properties such as frame counts and loop settings. The library enables the synchronization of a single animation instance across multiple views to ensure consistent playback. It supports loading GIF data from various sources, including assets, resources, URIs, byte arrays, files, and input strea
