Python reportlab垂直代码条代码39

从reportlab和python开始，这是我的小型医疗应用程序的最后一步

我找不到一个在为它设计的框架（侧薄框架）中设置垂直条形码的有效解决方案。其他一切正常（文档由五个框架、表格和其他条形码组成）。 也许框架是无用的，但我如何才能做到这一点

想法？ 谢谢

这是我的可怕代码，抱歉，我正在研究

好的，我用这个做了一些砖块：

我没有使用文本和字体制作的条形码，而是将其转换为易于旋转的图形（旋转方法）。

这非常简单。您只需旋转和平移条形码下方的画布，并交换其宽度和高度。因此，我继承了原始类并更改了

wrap

和

draw

方法

from reportlab.graphics.barcode.code39 import Extended39


class VerticalCode39(Extended39):
    def wrap(self, *args, **kwargs):
        w, h = super().wrap(*args, **kwargs)
        return h, w

    def draw(self):
        self.canv.rotate(90)
        self.canv.translate(0, -self.barHeight)
        super().draw()

VerticalCode39

的用法与

Extended39的用法相同

欢迎使用！在这个网站上，你应该尝试自己编写代码。之后，如果你有问题，你可以张贴你已经尝试了一个明确的解释什么是不工作，并提供一个解决方案。我建议你读一个好的问题和答案。另外，一定要带上笔记本并阅读。
