ClusterPainter.js

A fast library to display image clusters

Features:

Versatile: usable in any given div
Fast: the animations are based on the performant gsap library, therefore extremely fast

##Demo##

Here you can see the library in action

npm

	npm install cluster-painter

Embed the libary:

	var ClusterPainter = require("cluster-painter")

Here is a typical html file

 <!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <title>ClusterPainter</title>

	<link rel="stylesheet" href="node_modules/cluster-painter/css/clusterPainter.css">

  </head>

  <body>
    <div id = "container">
        <div id = "1" class = "button">1</div>
        <div id = "2" class = "button">2</div>
        <div id = "3" class = "button">3</div>
        <div id = "4" class = "button">4</div>
        <div id = "5" class = "button">5</div>          

        <select id = "Types" class="select">
            <option selected>Select</option>
                <option selected>default</option>
                <option >foto</option>
                <option>film</option>
        </select>               
    </div>
    <div id = "scenery"></div>
  </body>
</html>

Generating cluster data

To generate a cluster file, create an image folder with the name images, place all your images therein and then run the following command

	node node_modules/cluster-painter/create_cluster.js

In case you want to use another folder name (or another timeframe), you have to modify the create_cluster.js file

var x = new TV({
                path: "./images",             // here you have to pass the folder
                filename: "cluster.json",     // **please leave this unchanged!**
                callback: null,
                timeframe: "day"   // valid entries are [minute][hour][day][week][month][year]
                });

If you have followed these instructions, you have prepared your image data sufficiently.

Working with the npm version

The library is optimized for a browserified client side use. So you can use the handy require call instead adding resources to your html file.

The only resource you have to embed manually is a link to the *.css which is necessary for a decent visual result

    <link rel="stylesheet" href="node_modules/cluster-painter/css/clusterPainter.css">

The basic idea is that you have a super-simple api (and not have to worry how it works).

However, it's nice if something is working right from the start. To get accomodated to the library I recommend embedding the following snippet to your html code


  		<div id = "1" class = "button">1</div>
  		<div id = "2" class = "button">2</div>
  		<div id = "3" class = "button">3</div>
  		<div id = "4" class = "button">4</div>
  		<div id = "5" class = "button">5</div>    		
  		
  		<select id = "Types" class="select">
    		<option selected>Select</option>
    			<option selected>default</option>
    			<option >foto</option>
    			<option>film</option>
		</select>
  		  		
  	</div>
  	<div id = "scenery"></div>

In the index.js (or whereever you want to require cluster-painter), you can invoke the clusterPainter object, like this:

		var cluster = new ClusterPainter({
								   source: "cluster.json",	
								   css_class: "standard",
								   div: "scenery",
								   type: "default"
								   });

the source parameter takes the json file you have created with the first step.
the css_class paramater refers to the style class that the images shall use
the div parameter allows the library to operate in a given div
the type parameter specifies the animation type. Actually, default, foto and film are supported

The full code of the index.js, file could look like this. Here the interaction part is added which fits to the supposed html-code. However, invoking the clusterPainter is easy, you just have to pass a paint command and then the id of the image cluster

	/*jslint vars: true, plusplus: true, devel: true, nomen: true, indent: 4, maxerr: 50 */ /*global define */
	var $               = require('jquery');
	var ClusterPainter  = require('cluster-painter');
	
	
	  
	    $(document).ready(function(){
	        "use strict";
	
	
	        var cluster = new ClusterPainter({
	                                   source: "cluster.json",  
	                                   css_class: "standard",
	                                   div: "scenery",
	                                   type: "foto"
	                                   });
	
	
	      
	
			 
	         $(".button").click(function(){
	            var id = parseInt($(this).attr("id"), 10) -1;
	            cluster.paint(id);
	        });
	        
	        $("#Types").change(function(){
	            
	            var v = $(this).val();
	            cluster.set_type(v);
	        });
	        
	
	    });
	
	});

If you want to change the dislay type, you write:

   	cluster.paint[id]

default effect

photographs effect

filmstrip effect
