我正在尝试编写一个场景，其中有一个例程将输入作为要编码的数据以及其他参数（例如条形码高度和宽度）。然后，该例程对条形码进行编码，并将数据转换为条形码编码形式，并将其作为字符串返回。
我尝试了一些外部库，发现它们只返回图像（PNG，GIF），但我正在考虑获取我提供给路由的数据的条形码图像的十六进制格式。
此外，如果可以通过相对便宜的操作来实现结果并且实现该结果的过程稳定且没有错误，那就太好了。
任何人都知道任何外部库的任何指针如何实现这一点？
Im trying to code a scenario wherein there is a routine that takes in input as the data to encode and other parameters like barcode height and width. The routine then encodes the barcode and converts the data into the barcode encoding form and returns this as a he string.
I have tried out a few external libraries and have found them to only return an image(PNG,GIF) but Im looking at getting the resulting hex format of the barcode image for the data that I feed to the routing.
Also, it would be great if the result can be achieved through relatively inexpensive operations and the process of accomplishing the same being stable and not buggy.
Anyone know of any external library of any pointers on how this can be achieved ?

让我们定义条形码创建的 3 个步骤：
如果我理解正确，您需要的是步骤 2 的结果。通常这并不太困难，但首先您需要定义您使用的条形码格式。
Let's define 3 steps for the barcode creation:
If I undestood correctly, you want the result of step 2. Usually this isn't too difficult, but first you need to define which barcode format are you using.
最好的选择是将每个条形码字符转换为以 Base64 表示的 PNG。然后，只需遵守符号学规则并将“图像”串在一起即可。下面是一个示例：
此图像流在浏览器中显示单词“Sample”的 Code 128 条形码。如果您需要真正的十六进制字符串，您可以获取 PNG 图像文件并将其转换。我想我不确定你所说的“馈送到路由”是什么意思。
Your best bet is to convert each barcode character into a PNG represented in base64. Then it is just a matter of sticking with the rules of the symbology and stringing the "images" together. Here's an example:

If you need a true hexadecimal string, you can take the PNG image file and convert it. I guess I am uncertain what you mean by "feed to the routing".
