如何使用 KiCAD pcbnew 插件 Python API 获取封装图形元素

English Deutsch 简体中文

查看我们之前的文章 如何使用 KiCAD pcbnew 插件 Python API 获取所有封装列表 和 如何使用 KiCAD pcbnew 插件 Python API 获取所有选中的封装 了解如何获取封装对象的更多信息。

一旦你有 pcbnew.FOOTPRINT 对象，你可以使用以下命令获取其图形元素（基本上是封装中的线、矩形、圆等 - 但不包括任何丝印标签）

footprint_graphical_elements.py
footprint.GraphicalElements()

示例：

footprint_graphical_iter.py
for graphical_element in footprint.GraphicalItems():
    print(graphical_element)

输出：

output.txt
<pcbnew.FP_TEXT; proxy of <Swig Object of type 'FP_TEXT *' at 0x7fc47f2c41e0> >
<pcbnew.FP_SHAPE; proxy of <Swig Object of type 'FP_SHAPE *' at 0x7fc47f0f10b0> >
<pcbnew.FP_SHAPE; proxy of <Swig Object of type 'FP_SHAPE *' at 0x7fc47f2c69d0> >
<pcbnew.FP_SHAPE; proxy of <Swig Object of type 'FP_SHAPE *' at 0x7fc47f2c6d30> >
<pcbnew.FP_SHAPE; proxy of <Swig Object of type 'FP_SHAPE *' at 0x7fc47f0f10e0> >
<pcbnew.FP_SHAPE; proxy of <Swig Object of type 'FP_SHAPE *' at 0x7fc47f2c6cd0> >
<pcbnew.FP_SHAPE; proxy of <Swig Object of type 'FP_SHAPE *' at 0x7fc47f2c6ca0> >
<pcbnew.FP_SHAPE; proxy of <Swig Object of type 'FP_SHAPE *' at 0x7fc47f0f38d0> >
<pcbnew.FP_SHAPE; proxy of <Swig Object of type 'FP_SHAPE *' at 0x7fc47f2c68b0> >
<pcbnew.FP_SHAPE; proxy of <Swig Object of type 'FP_SHAPE *' at 0x7fc47f2c41e0> >
<pcbnew.FP_SHAPE; proxy of <Swig Object of type 'FP_SHAPE *' at 0x7fc47f0f10b0> >
<pcbnew.FP_SHAPE; proxy of <Swig Object of type 'FP_SHAPE *' at 0x7fc47f2c69d0> >
<pcbnew.FP_SHAPE; proxy of <Swig Object of type 'FP_SHAPE *' at 0x7fc47f2c6d30> >

你可以使用以下方式过滤它们

filter_graphical_items.py
fp_texts: list[pcbnew.FP_TEXT] = [
    item for footprint in selected_footprint.GraphicalItems()
    if type(item).__name__ == 'FP_TEXT'
]
fp_shapes: list[pcbnew.FP_SHAPE] = [
    item for footprint in selected_footprint.GraphicalItems()
    if type(item).__name__ == 'FP_SHAPE'
]
