HTML5 Inline SVG and HTML5 Drag and Drop
Sample of the pdf document :
What is SVG?
- SVG stands for Scalable Vector Graphics
- SVG is used to define vector-based graphics for the Web
- SVG defines the graphics in XML format
- SVG graphics do NOT lose any quality if they are zoomed or resized
- Every element and every attribute in SVG files can be animated
- SVG is a W3C recommendation
SVG Advantages
Advantages of using SVG over other image formats (like JPEG and GIF) are:
- SVG images can be created and edited with any
text editor
- SVG images can be searched, indexed, scripted,
and compressed
- SVG images are scalable
- SVG images can be printed with high quality at
any resolution
- SVG images are zoomable (and the image can be
zoomed without degradation)
Browser Support
Internet Explorer 9, Firefox, Opera, Chrome, and Safari support inline SVG.
Embed SVG Directly Into HTML Pages
In HTML5, you can embed SVG elements directly into your HTML page:
Example
<!DOCTYPE html>
<html>
<body>
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" height="190">
<polygon points="100,10 40,180 190,60 10,60 160,180"
style="fill:lime;stroke:purple;stroke-width:5;fill-rule:evenodd;">
</svg>
</body>
</html>
<html>
<body>
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" height="190">
<polygon points="100,10 40,180 190,60 10,60 160,180"
style="fill:lime;stroke:purple;stroke-width:5;fill-rule:evenodd;">
</svg>
</body>
</html>
Differences Between SVG and Canvas
SVG is a language for describing 2D graphics in XML.
Canvas draws 2D graphics, on the fly (with a JavaScript).
SVG is XML based, which means that every element is available within the
SVG DOM. You can attach JavaScript event handlers for an element.
In SVG, each drawn shape is remembered as an object. If attributes of an
SVG object are changed, the browser can automatically re-render the shape.
Canvas is rendered pixel by pixel. In canvas, once the graphic is drawn, it
is forgotten by the browser. If its position should be changed, the entire
scene needs to be redrawn, including any objects that might have been covered
by the graphic.
