我可以将图像设置为*不*自动调整大小吗?
Can I Set an Image to *Not* Auto-Resize?
我有一个 "template" 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 ClosedXML 使用它来填充数据。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,返回它以从网络应用程序下载,诸如此类。
静态模板文件中的一个单元格有图像。该行上的另一个单元格需要自动扩展以适应带有回车 returns 的换行文本。当设置上面的 WrapText
属性 时,行的自动扩展工作正常。然而,image 也在扩展它的高度。 (因此变得明显扭曲。)
在文件本身中,我右键单击图像以设置其格式,并在 "Size & Properties" 下明确选择 "Don't move or size with cells"。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。
我尝试过的另一件事是以某种方式 "separate" 行中的图像,方法是将其放入文本框内。但是,图像和文本框似乎都在单元格上方 "float",并且图像不能放在文本框内(或者我不知道如何放置)。
ClosedXML 似乎对图像没有太多支持(除非我只是没有看到它)。在此设置中是否有任何方法可以防止此图像随行自动调整大小?
我遇到了类似的问题。我的解决方案是为图像使用绝对定位的锚点,出于某种原因你不能在 Excel 本身中这样做...
我使用与 here 中的代码类似的代码构建控制台应用程序以使用 OpenXML SDK 生成模板 Excel 文件。锚代码:
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());
