照相机形状

照相机形状，顾名思义，是表单中引用区域的镜像。它是一个动态图像，这意味着引用区域的任何变化也会反映在图像中。

相机形状可以移动、调整大小、旋转并支持 Excel I/O。它们也可以与其他形状组合或取消组合，并从一个表单复制粘贴到另一个。

限制

在 SpreadJS 中，相机形状不会捕获指定单元格范围内的任何图片、形状或图表。
它不支持文本编辑、文本格式或调整功能。

注意: 当包含图片、形状或图表的相机形状导出到Excel时，Excel中会显示SpreadJS不支持的对象（图片、形状或图表）。

使用场景

考虑一个示例，其中维护超市中不同产品的销售数据以分析销售趋势。不同产品类别（如水果、蔬菜、面包、肉类等）的数据保存在电子表格的不同工作表中。

汇总的月度销售数据显示在合并的“Dashboard”工作表上，该工作表显示了不同产品类别中产品销售的相机形状。对销售数据所做的任何更改也会反映在“Dashboard”表中。
