d3-to-image v1.0.1

D3-TO-IMAGE

This library is exclusive dedicated to D3 implemented in AngularJS. So, it will be useful to D3 manually added over AngularJS, NVD3 and angularjs-nvd3

Let's improve this doc in a future.

How to implement it in AngularJS

Here you have some help to implement it in AngularJS.

• In bower.json, add: "d3-to-image": "^1.0.0",.
• In your index.html add <script src="[path]/d3-to-image/lib/d3-to-image-ngDirective.min.js"></script>.
• Add ngD3ToImage as dependency in your App, doing:

angular
  .module('yourAwesomeApp', [
      'ngRoute',
      // ...
      'ngD3ToImage' // <<< Add this!
  ])

• Then, for example, add a button that will call a exportPNG function to "run the export process", doing:

  <a ng-click="exportPNG()">Export SVG to PNG</a>

• Then, define your callback function that will be called when the image finished to be created:

$scope.d3ToImageCallback = function(imageFormats) {
    // Let's use FileSave library to download the image
    saveAs(imageFormats.blob, 'myChart.png');
};

• Now, wrap your SVG with your new directive, doing:

<d3-to-image data-try-to-fix="true"
             callback="d3ToImageCallback"
             export="exportPNG">
    <svg...></svg> <!-- Here you can have D3, NVD3, or whatever. -->
</d3-to-image>

The try-to-fix is passed to the svg-2-iamge library to force to improve cross browser compatibility
