如何实现条形码的恒定宽度；无论条形码数据如何 [英] How to achieve constant width for barcodes; regardless of barcode-data

问题描述

目前，我正在编程一个标签书写器(如果需要的话，它是Java的QL-570兄弟)，以打印具有不同ID的条形码.条形码数据的长度可以从〜17个字符到〜3个字符不等.

Currently I'm programming a label-writer (Brother QL-570, if it matters, in Java) to print barcodes with different ID's. The length of the barcode data can vary from ~17 characters to ~3.

但是，鉴于我已经正确理解了条形码的概念，因此数据越多-条形码将变得越宽.

However, given that I've understood the barcode-concept correctly, the more data - the wider will the barcode become.

如果所有条形码都具有相同且恒定的大小，则我更愿意:无论数据长度如何. (如果条形码没有填满标签，看起来会不好看；如果条形码太大，它也不会(工作))

I'd prefer if all barcodes had the same, contstant size: no matter data-length. (It won't look good if the barcode doesn't fill up the label, nor will it (work) if it's too large)

当标签为固定尺寸(即29mm x 90mm)时，如何处理?您/您的公司如何解决此问题的?二维条码不是一种选择.可悲的是.

How can one handle this when the labels are at a fixed size (i.e 29mm x 90mm)? How did you / your company solve this problem? 2D-barcodes aren't an option. Sadly.

推荐答案

如果您必须并排比较不同宽度的条形码，这看起来会很有趣，但是我公司通过定义每个符号来解决该问题1x ??位图并将其缩放到应用程序所需的大小.例如，每个代码128符号(停止除外)为11个像素宽.然后，我们的字体"定义了107个字符，每个字符都是1x11黑白位图(PNG).

It's going to look kinda funny if you have to compare barcodes of different widths side-by-side, but my company solved it by defining each symbol in terms of a 1x?? bitmap and scaling it up to the size required for the application. For example, each code 128 symbol, except Stop, is eleven pixels wide. Our "font" then has 107 characters defined, each a 1x11 black and white bitmap (PNG).

如果您对垂直和水平尺寸的控制足够多，它将条形码更容易地安装到所提供的空间中.

It makes fitting the barcode into the space provided much simpler if you have that much control over vertical and horizontal dimensioning.

这是一个类似于上图的快速示例:

请注意，为每个字符指定了尺寸，条形码通常将以8或更大的宽度进行扫描(取决于打印质量).条形码中的所有字符都需要相同的宽度.请记住，您的水平安静区域是条形宽度的函数，因此请尝试在标签的每一侧至少保留两个字符宽度.

Note that the dimensions are specified for each character and the barcodes will generally scan at a width of 8 or higher (depending on print quality). All characters within a barcode need identical widths. Remember that your horizontal quiet zone is a function of bar width, so try to keep at least two character widths to each side on the label.
