ezdxf python - 如何在布局的绘图设置中设置绘图透明度配置？

Question

我有一个代码可以绘制使用 ezdxf 创建的布局，但我在设置绘图透明度选项时遇到问题，因为我有一个带有图像的外部参考，我希望其透明度为 40%。

这是我用于绘制整个 dxf 文件的代码，但我不知道如何在绘图选项中将透明度选项设置为 True，我找不到此参考的文档。

如果当我在 ezdxf 中创建布局时，我可以为每个布局设置所有这些绘图选项，那就太好了。

doc = ezdxf.readfile(dxf_path)
layout = doc.layouts.new(name='layout_name')
layout.applyPlotOptions(papersize="ISO_full_bleed_A1_(841.00_x_594.00_MM)", plotsytle table='style.ctb', plottransparency=0.6, etc)

我非常感谢对此的任何帮助。

对于任何从事这方面工作的人来说，你都可以这样做
