"Raphaël": eine JavaScript-Bibliothek für SVG-Vektorgrafik in HTML-Seiten

Ein interessantes Open Source Projekt namens "Raphaël 1.0" von Dmitry Baranovskiy ermöglicht die Darstellung, Animation und interaktive Manipulation von SVG- und VML-Vektorgrafiken in DHTML-Seiten als eigenständiges DOM-Objekt. Aktuell werden von dem unter "MIT License" publizierten 54 kB großen JavaScript-Bibliothek ("raphael.js") die Web-Browser "Firefox 3.0", "Safari 3.0", "Opera 9.5" und "Internet Explorer 6.0" oder jeweils neuer unterstützt.

Informationen des Autoren

"Raphaël is a small JavaScript library that should simplify your work with vector graphics on the web. If you want to create your own specific chart or image crop and rotate widget, for example, you can achieve it simply and easily with this library.

Raphaël uses the SVG W3C Recommendation and VML as a base for creating graphics. This means every graphical object you create is also a DOM object, so you can attach JavaScript event handlers or modify them later. Raphaël’s goal is to provide an adapter that will make drawing vector art compatible cross-browser and easy.

Raphaël currently supports Firefox 3.0+, Safari 3.0+, Opera 9.5+ and Internet Explorer 6.0+.

Download and include raphael.js into your HTML page, then use it as simple as:

// Creates canvas 320 × 200 at 10, 50
var paper = Raphael(10, 50, 320, 200);
// Creates circle at x = 50, y = 40, with radius 10
var circle = paper.circle(50, 40, 10);
// Sets the fill attribute of the circle to red (#f00)
circle.attr("fill", "#f00");
// Sets the stroke attribute of the circle to white (#fff)
circle.attr("stroke", "#fff");
