获取 ShapeGroup 中的所有形状
Get all shapes in ShapeGroup
我的代码基本上是这样的：
worksheet.getDrawingPatriarch().getShapes().get(0)
这将 return XSSFShapeGroup 对象，但是从这一点上我不知道如何在组中获取 XSSFSimpleShape 或 XSSFShape。我想输出该组中每个形状的位置（行和列），但我不知道如何从组中提取它们。
要从形状组 (XSSFShapeGroup) 中获取 XSSFSimpleShape 或 XSSFShape 到现在为止无法使用 apache poi。
从 CTGroupShape 开始可以获得低级 CTShapes。但是“输出该组中每个形状的位置（行和列）”几乎是不可能的，因为该组只有一个锚点（行，列），并且所有分组的形状都相对于该锚点以单位 EMU（英制单位）。
所以我们可以得到形状组的锚点和EMU中组成员相对于该锚点的位置：

2016 年 10 月，当前 apache poi 版本为 3.14 或 3.15。现在在 2021 年，我们的版本为 5.0.0，并且情况发生了变化。
现在（自 apache poi 3.17 起）ShapeContainer 提供了一个遍历所有形状的迭代器。 XSSFShapeGroup 也实现了 ShapeContainer。所以上面的低级类用法就没有必要了。要从 XSSFDrawing and/or 中获取所有形状，现在 XSSFShapeGroup 很简单：

for (XSSFShape shape : container) {

if (shape instanceof XSSFConnector) {
XSSFConnector connector = (XSSFConnector)shape;
System.out.println(connector);
} else if (shape instanceof XSSFGraphicFrame) {
XSSFGraphicFrame graphicFrame = (XSSFGraphicFrame)shape;
System.out.println(graphicFrame);
} else if (shape instanceof XSSFPicture) {
XSSFPicture picture = (XSSFPicture)shape;
System.out.println(picture);
} else if (shape instanceof XSSFShapeGroup) { //we have a shape group
XSSFShapeGroup shapeGroup = (XSSFShapeGroup)shape;
System.out.println(shapeGroup);
traverseShapeContainer(shapeGroup); // we now can simply get the XSSFShapeGroup as ShapeContainer<XSSFShape>
} else if (shape instanceof XSSFSimpleShape) {
XSSFSimpleShape simpleShape = (XSSFSimpleShape)shape;
System.out.println(simpleShape);
}
}
}
public static void main(String[] args) throws Exception {
FileInputStream in = new FileInputStream("Shapegroup.xlsx");
XSSFWorkbook wb = (XSSFWorkbook)WorkbookFactory.create(in);
XSSFSheet sheet = wb.getSheetAt(0);
XSSFDrawing drawing = sheet.getDrawingPatriarch();
traverseShapeContainer(drawing);
}
}
