有人知道从字符串生成条形码图像(最好是代码39)并将其转换为base64字符串的工具,可以像这样使用:

var text = "11220"; // text to convert
var base64Str = textToBase64Barcode(text); // function to convert its input 
        // to a image formated in a base64 string like "data:image/jpeg;base64..."

？

当我试图编译甚至最简单的应用程序...除了只是一个小部件,我得到以下错误,我猜他们都是相同的错误,我不知道我做的不好或是什么的东西否则,我真的很感激你的帮助
