AndroidNote is a technical knowledge base and reference resource for Android development. It provides comprehensive guidance on application architecture, custom view development, and advanced graphics programming. The project is distinguished by its depth in visual implementation, covering pseudo-3D perspective projections via virtual cameras and complex 2D rendering using Bézier curves and PorterDuff color blending. It also provides detailed methodologies for app modularization and the management of internal libraries through private Maven repositories and JitPack. The reference surface ext

Two.js is a multi-backend graphics engine and vector drawing library that provides a unified API for creating two-dimensional graphics and animations. It functions as a renderer-agnostic abstraction layer, allowing users to generate vector shapes and paths that can be rendered via SVG, Canvas2D, or WebGL. The engine includes a scene graph manager to organize objects into hierarchical groups, enabling the propagation of collective transformations and parent-child relationships. It also features a headless graphics renderer, providing a node-based implementation for generating 2D drawings in se

AndroidPdfViewer is a user interface library for Android applications that provides a view for displaying PDF documents. It utilizes the PdfiumAndroid rendering engine to decode PDF files into bitmaps for display on mobile devices. The library includes built-in support for zooming, scaling, and scroll navigation. It allows for the loading of PDF data from various document sources and provides controls to adjust rendering quality and visual fidelity. The component handles mobile document navigation through features such as page filtering, hyperlink detection, and customizable scroll handles.

FastImageCache is an iOS image caching library that provides a persistent disk-based image store. It utilizes a persistent bitmap cache to store images in uncompressed formats and incorporates an image pre-processing pipeline to optimize assets before they are committed to storage. The library optimizes rendering performance by using memory-mapped image tables for constant-time retrieval and byte-aligned data layouts to prevent memory copies. It organizes images of identical dimensions into shared tables and manages disk space through a least-recently-used cache eviction system. The project

BGAQRCode-Android is a developer toolkit for Android that provides a library for scanning and recognizing QR codes and barcodes. It functions as a camera scanning framework and a barcode generator for creating one-dimensional and two-dimensional codes. The project includes a customizable UI kit for implementing branded scanning interfaces with adjustable dimensions, colors, and animation styles. It also provides tools for creating customized barcodes featuring specific color palettes and embedded logos. The toolkit manages camera hardware settings, including flashlight control, zoom levels,

Acest proiect este un set de date la scară largă cu schițe desenate manual, oferind milioane de desene vectoriale și bitmap-uri cu marcaj temporal pentru antrenarea modelelor de machine learning. Servește drept corpus de antrenament pentru viziune computerizată și set de date pentru rețele neuronale, constând în schițe umane categorisite, utilizate pentru a dezvolta algoritmi de clasificare și recunoaștere a imaginilor. Setul de date este disponibil ca un corpus de desene vectoriale care prezintă secvențe de linii și metadate, precum și ca array-uri numpy procesate. Aceste resurse susțin dezvoltarea clasificatorilor de desene și studiul tiparelor de desen uman. Datele sunt furnizate în mai multe formate, inclusiv date vectoriale brute în JSON delimitat prin linii noi, secvențe vectoriale normalizate și bitmap-uri grayscale. Include capabilități pentru partiționarea bazată pe categorii și scalarea coordonatelor pentru a asigura consistența între diferite eșantioane.

u8g2 este o bibliotecă de drivere pentru afișaje monocrome scrisă în C și C++ pentru randarea graficii și a textului pe ecrane OLED și LCD. Funcționează ca o bibliotecă grafică embedded și renderer de fonturi, oferind un strat de abstractizare hardware pentru a gestiona comunicarea cu controllerele de afișare. Biblioteca se distinge prin gestionarea flexibilă a memoriei, oferind atât maparea memoriei pe tot ecranul pentru desenare arbitrară, cât și buffering de cadre bazat pe pagini pentru a reduce consumul de RAM. Optimizează în continuare utilizarea resurselor prin randarea textului direct pe afișaj, care evită bufferele de memorie intermediare. Framework-ul acoperă desenarea geometrică monocromă pentru linii, casete și cercuri, alături de un sistem de fonturi care susține dimensiuni personalizate și hărți de fonturi monocrome pre-randate. Integrarea hardware este gestionată prin suport pentru interfețe SPI, I2C și paralele, cu capabilități suplimentare pentru oglindirea și rotirea imaginilor în trepte de nouăzeci de grade. Biblioteca include suport de build pentru sistemul de operare în timp real RT-Thread.

Hilo is an HTML5 game engine for building 2D games that run across browsers and devices. It renders graphics through Canvas, DOM, or WebGL backends, automatically selecting the best option for the target environment. The engine provides a complete game development solution with sprite, skeletal, and particle animation, along with a texture atlas system for efficient image loading and rendering. The framework distinguishes itself through its integration of the DragonBones skeletal animation engine, which drives bone-based character movement without frame-by-frame sprites, and its Chipmunk phys

The official rendering library for PAG (Portable Animated Graphics) files that renders After Effects animations natively across multiple platforms.

Perfetto is a platform for system-level performance tracing and analysis on Linux and Android. It combines a high-throughput trace recorder, a SQL-based query engine, and a browser-based visualizer into a single toolchain. The platform covers CPU scheduling and call-stack profiling, native and Java heap memory allocation tracking, GPU and graphics events, and system-wide counters such as CPU frequency and power consumption. The architecture decouples trace recording from offline analysis, using a compact protobuf format for event encoding and columnar storage for efficient SQL queries. The we
