从带有python的reportlab开始，这是我的小医疗应用程序的最后一步。
我无法找到一种工作解决方案，用于在为其设计的框架中设置垂直条形码（侧面薄框架）。其他一切都还可以（文件由五个框架，桌子，其他条形码组成）。 也许框架没用，但我怎么能这样做呢？
想法？ 感谢。
这是我可怕的代码，对不起，我正在研究它。

答案 0 :(得分：0)
好的，我设法用这个做了一些拼凑：
http://nullege.com/codes/search/reportlab.graphics.barcode.createBarcodeDrawing
我没有使用文字和字体制作条形码，而是将其转换成易于旋转的图形（旋转方法）。
答案 1 :(得分：0)
这出奇的简单。您只需要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 相同。
