Java中的条形码图像

Question

如何在Java中创建条形码图像？我需要能够输入数字并生成相应条形码图像的东西。请记住，我不想使用任何可用于此类任务的免费库。我只想用类文件来实现它。

Answer 1

是烧烤是个不错的选择。它的源代码可用。我个人尝试过根据我的需要使它可用。您可以看到代码理解它，然后为它编写自己的类。

试试以下网址：

Barbecue Source Code

Answer 2

您可以尝试使用Barbecue框架。但是，这是开源项目。

Answer 3

您的客户在使用Code 128 字体时遇到问题吗？我在网上发现了一些免费赠品，我使用字体比使用图像创建者更容易，而且它嵌入到PDF中，可以很好地用于基于Web的应用程序。

Answer 4

您可以将条形码字符作为图像嵌入base64吗？

如果是这样，图像是自包含的，您只需要一个字符串数组。抱歉尴尬的格式。
