我可以设置图像*不*自动resize？

我有一个“模板”Excel文件，为布局（一些合并的单元格，一些列宽等）设置了一些基本的东西，然后由ClosedXML用于填充数据。 在基本层面上，它就像下面这样简单：

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stream，从Web应用程序返回它下载，这种事情。

静态模板文件中的一个单元格具有一个图像。 该行上的另一个单元格需要自动展开以适应使用回车符打包文本。 当设置上面的WrapText属性时，行的自动扩展工作正常。 但是， 形象也在扩大其高度。 （因此变得严重扭曲。）

在文件本身中，我右键单击图像以设置其格式，在“大小和属性”下，我明确select了“不要移动或使用单元格大小”。 但是，通过ClosedXML交互进行行自动resize仍然导致图像resize。

我试过的另一件事是以某种方式将图像从行中“分离”出来，放在文本框中。 然而，它会出现，图像和文本框同样“浮动”上方的单元格和图像不能放置在文本框内（或者我不知道如何）。

看来，ClosedXML没有太多的支持图像（除非我只是没有看到它）。 有没有什么办法在这个设置，以防止这个图像自动调整行的大小？

我有一个类似的问题。 对我来说，解决scheme是使用绝对定位的图像的锚点，由于某种原因，你不能在Excel本身做…

我构build了一个控制台应用程序，使用与此处代码类似的代码，使用OpenXML SDK生成模板Excel文件。 代码为主播：

 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()); 

隐藏在紧急情况的代码片段中的完整代码：

 static void Main(string[] args) { string sFile = "ExcelOpenXmlWithImage.xlsx"; if (File.Exists(sFile)) { File.Delete(sFile); } BuildWorkbook(sFile); } private static void BuildWorkbook(string filename) { try { using (SpreadsheetDocument xl = SpreadsheetDocument.Create(filename, SpreadsheetDocumentType.Workbook)) { WorkbookPart wbp = xl.AddWorkbookPart(); WorksheetPart wsp = wbp.AddNewPart<WorksheetPart>(); Workbook wb = new Workbook(); FileVersion fv = new FileVersion(); fv.ApplicationName = "Microsoft Office Excel"; Worksheet ws = new Worksheet(); SheetData sd = new SheetData(); string sImagePath = "polymathlogo.png"; DrawingsPart dp = wsp.AddNewPart<DrawingsPart>(); ImagePart imgp = dp.AddImagePart(ImagePartType.Png, wsp.GetIdOfPart(dp)); using (FileStream fs = new FileStream(sImagePath, FileMode.Open)) { imgp.FeedData(fs); } NonVisualDrawingProperties nvdp = new NonVisualDrawingProperties(); nvdp.Id = 1025; nvdp.Name = "Picture 1"; nvdp.Description = "polymathlogo"; DocumentFormat.OpenXml.Drawing.PictureLocks picLocks = new DocumentFormat.OpenXml.Drawing.PictureLocks(); picLocks.NoChangeAspect = true; picLocks.NoChangeArrowheads = true; NonVisualPictureDrawingProperties nvpdp = new NonVisualPictureDrawingProperties(); nvpdp.PictureLocks = picLocks; NonVisualPictureProperties nvpp = new NonVisualPictureProperties(); nvpp.NonVisualDrawingProperties = nvdp; nvpp.NonVisualPictureDrawingProperties = nvpdp; DocumentFormat.OpenXml.Drawing.Stretch stretch = new DocumentFormat.OpenXml.Drawing.Stretch(); stretch.FillRectangle = new DocumentFormat.OpenXml.Drawing.FillRectangle(); BlipFill blipFill = new BlipFill(); DocumentFormat.OpenXml.Drawing.Blip blip = new DocumentFormat.OpenXml.Drawing.Blip(); blip.Embed = dp.GetIdOfPart(imgp); blip.CompressionState = DocumentFormat.OpenXml.Drawing.BlipCompressionValues.Print; blipFill.Blip = blip; blipFill.SourceRectangle = new DocumentFormat.OpenXml.Drawing.SourceRectangle(); blipFill.Append(stretch); DocumentFormat.OpenXml.Drawing.Transform2D t2d = new DocumentFormat.OpenXml.Drawing.Transform2D(); DocumentFormat.OpenXml.Drawing.Offset offset = new DocumentFormat.OpenXml.Drawing.Offset(); offset.X = 0; offset.Y = 0; t2d.Offset = offset; Bitmap bm = new Bitmap(sImagePath); //http://en.wikipedia.org/wiki/English_Metric_Unit#DrawingML //http://stackoverflow.com/questions/1341930/pixel-to-centimeter //http://stackoverflow.com/questions/139655/how-to-convert-pixels-to-points-px-to-pt-in-net-c DocumentFormat.OpenXml.Drawing.Extents extents = new DocumentFormat.OpenXml.Drawing.Extents(); extents.Cx = (long)bm.Width * (long)((float)914400 / bm.HorizontalResolution); extents.Cy = (long)bm.Height * (long)((float)914400 / bm.VerticalResolution); bm.Dispose(); t2d.Extents = extents; ShapeProperties sp = new ShapeProperties(); sp.BlackWhiteMode = DocumentFormat.OpenXml.Drawing.BlackWhiteModeValues.Auto; sp.Transform2D = t2d; DocumentFormat.OpenXml.Drawing.PresetGeometry prstGeom = new DocumentFormat.OpenXml.Drawing.PresetGeometry(); prstGeom.Preset = DocumentFormat.OpenXml.Drawing.ShapeTypeValues.Rectangle; prstGeom.AdjustValueList = new DocumentFormat.OpenXml.Drawing.AdjustValueList(); sp.Append(prstGeom); sp.Append(new DocumentFormat.OpenXml.Drawing.NoFill()); DocumentFormat.OpenXml.Drawing.Spreadsheet.Picture picture = new DocumentFormat.OpenXml.Drawing.Spreadsheet.Picture(); picture.NonVisualPictureProperties = nvpp; picture.BlipFill = blipFill; picture.ShapeProperties = sp; 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()); WorksheetDrawing wsd = new WorksheetDrawing(); wsd.Append(anchor); Drawing drawing = new Drawing(); drawing.Id = dp.GetIdOfPart(imgp); wsd.Save(dp); ws.Append(sd); ws.Append(drawing); wsp.Worksheet = ws; wsp.Worksheet.Save(); Sheets sheets = new Sheets(); Sheet sheet = new Sheet(); sheet.Name = "Sheet1"; sheet.SheetId = 1; sheet.Id = wbp.GetIdOfPart(wsp); sheets.Append(sheet); wb.Append(fv); wb.Append(sheets); xl.WorkbookPart.Workbook = wb; xl.WorkbookPart.Workbook.Save(); xl.Close(); } } catch (Exception e) { Console.WriteLine(e.ToString()); Console.ReadLine(); } }
