Getting started

Implementing this plugin is broken into two parts. Preparing your web-friendly data & Configuring lazy-line-painter.js

Preparing your SVG data
Create your Line art in your vector editor of choice

• Ensure there are no fills.
• No closed paths. i.e - Line needs a start and end.
• Crop Artboard nice & tight! Export as .SVG (Default export options are fine) Drop your .SVG into 'SVG to Lazy Line Convertor' on http://lazylinepainter.info/ Copy lazy line code and paste into your DOM ready function.

Configuring lazy-line-painter options
A number of attributes can be setup before the line art is Painted, these include;

'strokeWidth'    // Adjust width of stroke
'strokeColor'    // Adjust stroke color
'strokeCap'      // Adjust stroke cap  - butt  | round | square
'strokeJoin'     // Adjust stroke join - miter | round | bevel
'strokeOpacity'  // Adjust stroke opacity 0 - 1
'onComplete'     // Callback fired after animation finishes
'onStart'        // Callback fired just before animation starts
'delay'          // Delay before animation starts
'overrideKey'    // Set this property if you selector id doesn't match the key referencing your path data value within svgData.
'speedMultiplier' // slow down or speed up the animation
'drawSequential'  // true: draw each path sequentially, false, draw all at once
'reverse' // reverse drawSequence
'responsive' // true: responsive width and height

To apply these options to your element before Painting, pass lazylinepainter an object as an argument containing the attritubes you wish to alter;

$('#demo').lazylinepainter({
    	'svgData' : svgData, // the object containing the SVG path info
		'strokeWidth':7,
		'strokeColor':'#de8f8f'
	}
)

Note: The only required is the svgData object (which contains your path info). The svgData object should be structured like so for the plugin to be able to read.

var svgData = {
	'demo' : // name of your lazy line
	{
		'strokepath' : // this contains all your SVG path info
		[
			{
				'path': "M144.869,199c0....", // path string ,
			    'duration':300, // time taken to animate that path
			    'strokeColor':'#000000', // stroke color can be set individually
			    'strokeWidth':3 // stroke width can be set individually
			    'reverse': true	// reverse stroke individually
			}, {
				'path': "M155.85,29c0...."
			    'duration':1000
			}, {
				etc ...
		],
		'dimensions' : // dimensions of element
		{
			'width': 270,
			'height':266
		}
	}
}
