<h2>What is this?</h2> |
|
<p> |
|
Resemble.js analyses and compares images with HTML5 canvas and JavaScript. |
|
</p> |

<strong>Try it for yourself.</strong> |

<h2>Compare two images?</h2> |
|
<p> |
|
Drop two images on the boxes to the left. The box below will show a generated 'diff' image, pink areas show mismatch. This example best works with two very similar but slightly different images. Try for yourself! |
|
</p> |
|
<div id="image-diff" class="small-drop-zone"> |
|
Diff will appear here. |
|
</div> |
|

|
<div class="btn-group" id="buttons" style="display:none"> |
|
<button class="btn active" id="raw">Ignore nothing</button> |
|
<button class="btn" id="colors">Ignore colors</button> |
|
<button class="btn" id="antialising">Ignore antialiasing</button> |
|
</div> |
|
<br/> |
|
<br/> |
|
<div id="diff-results" style="display:none;"> |
|
<p> |
|
<strong>The second image is <span id="mismatch"></span>% different compared to the first. |
|
<span id="differentdimensions" style="display:none;">And they have different dimensions.</span></strong> |
|
</p> |
|
<p> |
|
Use the buttons above to change the comparison algorithm. Perhaps you don't care about color? Annoying antialiasing causing too much noise? Resemble.js offers multiple comparison options. |

<h2>Why?</h2> |
|
<p> |
|
Resemble.js can be used for any image analysis and comparison requirement you might have in the browser. However, it has been designed and built for use by the PhantomJS powered visual regression library <a href="https://github.com/Huddle/PhantomCSS" target="_blank">PhantomCSS</a>. PhantomCSS needs to be able to ignore antialiasing as this would cause differences between screenshots derived from different machines. |
|
</p> |
|
<p> |
|
Resemble.js uses the <a href="https://github.com/Huddle/PhantomCSS" target="_blank">HTML5 File API</a> to parse image data, and canvas for rendering image diffs. |

<h2>How can I use it?</h2> |
|
<p>Retrieve basic analysis on image.</p> |
|
<pre> |
|
var api = resemble(fileData).onComplete(function(data){ |
|
return data; |
|
/* |
|
{ |
|
red: 255, |
|
green: 255, |
|
blue: 255, |
|
brightness: 255 |
|
} |
|
*/ |
|
});</pre> |
|
<p>Use resemble to compare two images.</p> |
|
<pre> |
|
resemble(file).compareTo(file2).onComplete(function(){ |
|
return data; |
|
/* |
|
{ |
|
misMatchPercentage : 100, // % |
|
isSameDimensions: true, // or false |
|
getImageDataUrl: function(){} |
|
} |
|
*/ |
|
});</pre> |
