антикапча и base64

Здравствуйте. Нужно отправить капчу
POST to http://antigate.com/in.php
следующие поля:
method => base64
key => 2595b47679d8f01ffb87782e5655b555
body => CAPCHA_FILE_HERE_ENCODED_BASE64 ( + UUENCODE ! )
ext => FILE_EXTENSION
Объясните пожалуйста как правильно это сделать, а еще лучше подправьте код.
Вот как я пытаюсь отправить файл....

Получаю файл капчи в Base64

HTML:

var canvas = document.createElement('canvas'); 
canvas.width = "200";
canvas.height = "50";
var context = canvas.getContext('2d');
var img = new Image();  
img.onload = function(){
	context.drawImage(img, 0, 0);
}
img.src='....captcha.png';
var b64 = canvas.toDataURL("image/png");

теперь, на сколько я понял ине нужно закодировать base64 в UUENCODE . Как это сделать я не знаю, гугл не помог.

пытаюсь отправить содержимое в base64

HTML:

var fd = new FormData();
fd.append("method", "base64");
fd.append("key", "2595b47679d8f01ffb87782e5655b555");
fd.append("body", file);
fd.append("ext", "png");
var xhr = new XMLHttpRequest();
xhr.open("POST", "http://antigate.com/in.php", true);
	xhr.onreadystatechange=function() 
		{
		if(xhr.readyState == 4) 
			{
			if (xhr.status == 200) {
			//console.log(xhr.responseText);
			alert(xhr.responseText);
			}
			else alert("Ошибка обработки запроса!");
			}
		}
xhr.send(fd);

ошибка ERROR_WRONG_FILE_EXTENSION.

Помогите пожалуйста

 

http://phpjs.org/functions/convert_uuencode:769

 

попрбовал
var file=convert_uuencode(b64);

В консоли Хрома ошибка
Uncaught TypeError: Object [object DOMWindow] has no method 'is_scalar'

 

ext должен равняться jpg, gif или png.

 

добавил функции
