我可以将图像设置为*不*自动调整大小吗？

Question

我有一个＆＃34;模板＆＃34; Excel文件，其中包含为布局设置的一些基本内容（一些合并的单元格，一些列宽等），然后由ClosedXML用于填充数据。在基本层面上，它很简单：

var workbook = new XLWorkbook(filePath);
workbook.Worksheets.Single().Cell(1, 4).Value = someTextValue;
workbook.Worksheets.Single().Cell(1, 4).Style.Alignment.WrapText = true;
// set other values, etc.

整个过程涉及将文件复制到另一个流，将其从Web应用程序返回以供下载。

静态模板文件中的一个单元格有一个图像。该行上的另一个单元格需要自动展开以适应回车文本。在上面设置WrapText属性时，行的自动扩展可以正常工作。但是，图像也在扩大它的高度。 （因此变得非常扭曲。）

在文件本身中，我右键单击图像以设置其格式，并在＆＃34;尺寸＆amp;属性＆＃34;我已经明确选择了“不要使用单元格移动或调整大小”＃34;。但是，通过ClosedXML交互自动调整行的大小仍然会导致图像调整大小。

我尝试的另一件事是以某种方式＆＃34;分开＆＃34;将行中的图像放在文本框内。然而，看起来图像和文本框同样地“浮动”＃34;在单元格上方，图像不能放在文本框内（或者我不知道如何）。

似乎ClosedXML对图像没有太多支持（除非我没有看到它）。在此设置中是否有任何方法可以防止此图像使用行自动调整大小？

我有类似的问题。我的解决方案是为图像使用绝对定位的锚点，由于某种原因，您无法在Excel中执行此操作...

我构建了一个控制台应用程序，使用与here中的代码类似的代码，使用OpenXML SDK生成模板Excel文件。锚的代码：

Position pos = new Position();
pos.X = 0;
pos.Y = 0;
Extent ext = new Extent();
ext.Cx = extents.Cx;
ext.Cy = extents.Cy;
AbsoluteAnchor anchor = new AbsoluteAnchor();
anchor.Position = pos;
anchor.Extent = ext;
anchor.Append(picture);
anchor.Append(new ClientData());
