signature_pad is a JavaScript library and drawing tool for capturing handwritten digital signatures on an HTML5 canvas. It provides a handwriting capture interface that transforms raw mouse or touch inputs into smooth, professional-looking lines. The project uses Bézier curve interpolation to smooth jagged input points into fluid strokes. It supports the configuration of drawing aesthetics, including pen color, background color, and line width, and includes a history management system for undoing and restoring drawing actions. The library handles the serialization of signature data into poin
This project is a collection of technical demonstrations and prototypes that showcase various HTML5 APIs, multimedia capabilities, and web standard implementations. It serves as a frontend technology sandbox and a gallery of implementation proofs-of-concept for modern browser features. The collection includes specialized showcases for HTML5 multimedia, featuring the manipulation of audio, video, and real-time media streams. It also provides a series of experiments focused on prototyping web capabilities to verify technical feasibility and browser support in live environments. The project cov
Simpl is an HTML, CSS, and JavaScript example library that provides a collection of minimal functional demonstrations of core web technologies and native browser APIs. It serves as a reference implementation and pattern gallery for frontend development, offering practical examples of how to implement common web features. The project showcases a wide range of browser capabilities, including real-time web communication via WebSockets and WebRTC, responsive web design techniques for adaptive layouts, and the implementation of offline workflows using service workers. It also provides demonstratio
This project is a collection of reusable React hooks designed to wrap browser APIs, manage state persistence, and handle DOM observation. It provides a consistent interface for integrating native browser capabilities directly into the React component lifecycle. The library includes specialized toolkits for monitoring the browser environment, such as window resizing, network connectivity, and viewport visibility. It also provides mechanisms for managing execution timing through debouncing, throttling, and the control of timeouts and intervals. Additional capabilities cover state management wi
jspaint is a web-based reimplementation of Microsoft Paint, built entirely in JavaScript to run in a browser. It recreates the classic desktop application by reverse-engineering the original Win32 API calls and event handling, rendering the entire interface onto an HTML5 canvas for pixel-perfect retro graphics. The project preserves the original file format compatibility with BMP, PNG, GIF, and JPEG, ensuring exact pixel data matches the legacy application.
The main features of 1j01/jspaint are: Canvas Rendering, Legacy Image Format Preservation, Win32 API Emulation Layers, JavaScript Plugin Systems, Image Processing Offloading, Undo-Redo History.
