svg.export.js

A plugin for the svgjs.com library export a whole svg canvas or just a single element.

Svg.export.js is licensed under the terms of the MIT License.

Usage

Include this plugin after including the svg.js library in your html document.

To export the whole svg canvas:

var draw = SVG('paper').size(400, 400)
var rect = draw.rect(100, 100)

var svgExport = rect.exportSvg()

By default the exported svg is compressed. If you want to have a more readable output you can require whitespace:

var svgExport = draw.exportSvg({ whitespace: true })

The default whitespace indentation is two spaces. You can also define you own indentation style, with tabs for example:

var svgExport = draw.exportSvg({ whitespace: '\t' })

Finally, if you are exporting the whole svg canvas you can set a target width and height. This is especially useful if you are using a the viewbox() method on your svg canvas:

var draw = SVG('paper').size(400, 400).viewbox(0,0,200,200)
var rect = draw.rect(100, 100)

var svgExport = draw.exportSvg({ width: '150mm', height: '150mm' })

Exporting elements

Individual elements can be exported as well:

var draw = SVG('paper')
var rect = draw.rect(100, 100)

var exportedRect = rect.exportSvg()

Export attributes

In some cases you might want elements to be exported with different attribute values. This can be done with the exportAttr() method:

var draw = SVG('paper').size(400,400)
var rect = draw.rect(100, 100).fill('#333').exportAttr({ fill: '#f06' })

var svgExport = draw.exportSvg({ whitespace: true })

Will produce:

<?xml version="1.0" encoding="UTF-8"?>
<svg width="400" height="400" xmlns="http://www.w3.org/2000/svg" version="1.1" xmlns:xlink="http://www.w3.org/1999/xlink">
  <desc>Created with svg.js [http://svgjs.com]</desc>
  <defs>
  </defs>
  <rect fill="#f06" width="100" height="100">
  </rect>
</svg>

Not unlike the attr() method, exportAttr() will also act as a getter if no argument is supplied:

rect = exportAttr()
// => { fill: '#f06' }

Excluding elements

In some cases you might want to exclude some elements from the export and here is how to achieve that:

var draw = SVG('paper')
var rect = draw.rect(100, 100)
var circle = draw.circle(100)

var svgExport = draw.exportSvg({
  exclude: function() {
    return this.type == 'circle'
  }
})

A great way to approach this is to bind a data attribute to the elements you want to be excluded:

var draw = SVG('paper')
var rect = draw.rect(100, 100)
var circle = draw.circle(100).data('exclude', true)

var svgExport = draw.exportSvg({
  exclude: function() {
    return this.data('exclude')
  }
, whitespace: true
})

This will produce the following output:

<?xml version="1.0" encoding="UTF-8"?>
<svg width="100%" height="100%" xmlns="http://www.w3.org/2000/svg" version="1.1" xmlns:xlink="http://www.w3.org/1999/xlink">
  <desc>Created with svg.js [http://svgjs.com]</desc>
  <defs>
  </defs>
  <rect width="100" height="100">
  </rect>
</svg>
