Hi this is a test

+ Hi WHat's app guys$$$
+ + + + + +
+

Identicon.js

+
+
+

Basic Usage

+

Specify just a hash, use default background color, margins, and size.

+
+  var hash = 'd6fe8c82fb0abac17a702fd2a94eff37';
+  var data = new Identicon(hash).toString();
+  document.write('<img src="data:image/png;base64,' + data + '">');
+ +
+
+ +
+
+

Options Usage

+

Specify a hash and an options object to customize background color, margins, and size.

+
+  var hash = 'd6fe8c82fb0abac17a702fd2a94eff37';
+  var options = {
+    foreground: [255, 255, 255, 255],
+    background: [0, 0, 0, 255],
+    margin: 0.2,
+    size: 128
+  };
+  var data = new Identicon(hash, options).toString();
+  document.write('<img src="data:image/png;base64,' + data + '">');
+ +
+
+ +
+
+

Automatic Usage

+

Don't specify a hash to have one automatically generated based on the current time.

+
+  var data = new Identicon().toString();
+  document.write('<img src="data:image/png;base64,' + data + '">');
+ +
