When a user visits a page, the fingerprinting script first draws text with the font and size of its choice and adds background colors (1). Next, the script calls Canvas API’s ToDataURL method to get the canvas pixel data in dataURL format (2), which is basically a Base64 encoded representation of the binary pixel data.
The canvas element is part of HTML5 and allows for dynamic, scriptable rendering of 2D shapes and bitmap images. It is a low level, procedural model that updates a bitmap. HTML5 Canvas also helps in making 2D games. While the HTML5 canvas offers its own 2D drawing API, it also supports the WebGL API to allow 3D rendering with OpenGL ES.
The Enlightenment Foundation Libraries (EFL) are a set of graphics libraries that grew out of the development of Enlightenment, a window manager and Wayland compositor. [2] The project's focus is to make the EFL a flexible yet powerful and easy to use set of tools to extend the capabilities of both the Enlightenment window manager and other ...
OpenFL supports rendering in OpenGL, Cairo, Canvas, SVG and even HTML5 DOM. In the browser, WebGL is the default renderer but if unavailable then canvas (CPU rendering) is used. [21] Certain features (shape.graphics or bitmapData.draw) will use CPU rendering, but the display list remains GPU accelerated as far as possible. [21]
Provides a common configurable interface for other components to interact with different types of data, from simple JavaScript arrays to online servers over XHR. Drag and drop The YUI Drag and Drop Utility makes it easy to make elements "draggable" and to create drop targets that respond to drag events. Element
Ajax (also AJAX / ˈ eɪ dʒ æ k s /; short for "asynchronous JavaScript and XML" [1] [2]) is a set of web development techniques that uses various web technologies on the client-side to create asynchronous web applications.
Ext JS is a JavaScript application framework for building interactive cross-platform web applications [2] using techniques such as Ajax, DHTML and DOM scripting. It can be used as a simple component framework (for example, to create dynamic grids on otherwise static pages) but also as a full framework for building single-page applications (SPAs).
jQuery's syntax is designed to make it easier to navigate a document, select DOM elements, create animations, handle events, and develop Ajax applications. jQuery also provides capabilities for developers to create plug-ins on top of the JavaScript library.
