的PNG文件格式元数据
问题描述：
我试图PNG文件转换为字节机智以下
I tried to convert the PNG file into bytes wit the code below
var enc:Base64Encoder = new Base64Encoder();
enc.encodeBytes(bytes);
var base64data:String = enc.drain();
trace("base64data : "+base64data);
trace("end of base64data ");
但我得到的是字符，像这样
But what i get is a chunk of characters like this
