# Raphaël SVG Import plugin

## What is it?
An extension to the Raphael Vector Library.<br/>
It enables Raphael to import raw SVG data.

Fork Notes
==========

This is a fork of [raphael.svg-import](https://github.com/wout/raphael-svg-import).
When the original raphael-svg-import reached 0.0.3, a major backwards-incompatible change was introduced.
Instead of parsing SVG documents, it used regular expressions. This was undesirable for several reasons:

* Used regular expressions to parse XML. Rebuilding something that browsers can do natively.
* Loss of document structure. Groups (`<g>`) are lost.
* Additional steps needed to load a svg file.

Usage
-----
See demo.html for the full example. Use AJAX to retrieve your SVG file as an XML document.
Then use importSVG() to convert the SVG into a raphael.js set:

```javascript
jQuery(document).ready(function(){
  jQuery.ajax({
    type: "GET",
    url: "assets/demo.svg",
    dataType: "xml",
    success: function(svgXML) {
      var paper = Raphael(10, 10, 800, 600);
      var newSet = paper.importSVG(svgXML);
    }
  });
});
```
If you want the Raphael paper dimensions to automatically match the SVG:
```javascript
jQuery(document).ready(function(){
  jQuery.ajax({
    type: "GET",
    url: "assets/demo.svg",
    dataType: "xml",
    success: function(svgXML) {
      var root = svgXML.getElementsByTagName('svg')[0].getAttribute('viewBox').split(' ');
      var width = root[2],
          height = root[3];
      var paper = Raphael(width, height);
      var newSet = paper.importSVG(svgXML);
    }
  });
});
```
If you want to import the SVG from an element within the page you can access to the element:
```xml
<svg id="mysvg" version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="500px" height="500px" viewBox="0 0 500 500" enable-background="new 0 0 500 500" xml:space="preserve">
	<circle opacity="0.3" fill="#FF0000" enable-background="new" cx="251.5" cy="255.5" r="179"/>
</svg>
```
And you can access to the svg element by its id:
```javascript
var paper = Raphael(10, 10, 500, 500);
var newSet = paper.importSVG(document.getElementById('mysvg'));
```
In the assets folder a demo.svg file is provided.<br/>
Nothing fancy but it gives you a starting point.

## Contributing to Raphael SVG Import Classic

* Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
* Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
* Fork the project
* Start a feature/bugfix branch
* Commit and push until you are happy with your contribution
* Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
* You can contribute a broken test case without a fix

### Testing

#### Qunit

Open `tests/qunit.html` in your targeted browers. A command line
version can be run based on webkit with `grunt qunit`. A hosted version can be
found [here][qunit tests].

#### Visual

Open `tests/visual_tests.html` in your targeted browsers.
A hosted version can be found [here][visual tests].

#### Old IE testing

Follow the same instructions as above IE. When looking at the Qunit test in IE,
all tests will fail, but the output should look the same as other browsers.

#### From the command line

```bash
$ grunt test
Running "jshint:all" (jshint) task
>> 2 files lint free.

Running "qunit:all" (qunit) task
Testing tests/qunit.html .............OK
>> 20 assertions passed (57ms)

Done, without errors
```

Final Notes
-----------
I've tried keeping all the files as close to the original as possible.
So there are lots of files not relevant to this fork in the tree.

There is a bug in the minified version of of Raphael.js that most people use.
It's best to just grab the uncompressed source and minify it yourself.
