c# - 如何以编程方式将图像插入表格单元格并自动缩放以适应

问题描述

我自动将图像插入到 ms word 文档表格单元格中。但是.. 我需要自动缩放图像（不丢失 dpi）以适合表格单元格。有 2 个表格单元格，它们都应该占据表格分配宽度的 50%。所以..如您所见...图像未缩放以适合表格单元格。并且单元格宽度不相等。基本上，图像应该放在 2 列中，每个图像行之后都有一个空白行。对于每 6 个图像，将插入一个带有新表格的新页面。我发布图像和代码

图像不缩放

解决方案

如果将行高或列宽设置为精确值，则图像应缩放到该尺寸。

执行此操作时，还要确保表格自动调整行为不允许单元格扩展。这意味着当添加一个表设置DefaultTableBehavior为wdWord8TableBehavior. AutoFitBehavior应该是wdAutoFitFixed。

如果一个表已经存在，也可以专门设置最后一个。在问题的代码中，我发现这是不正确的：

axTable.AutoFitBehavior(WdAutoFitBehavior.wdAutoFitWindow);

您还需要测试使用百分比作为 PreferredWidthType 是否支持精确设置。这可能需要更改为使用积分。
