Aspose.Cells 智能标记也支持图像标记。本节介绍如何使用智能标记插入图片。

图像参数

用于管理图像的智能标记参数。

  • 图片:FitToCell - 使图像自动适合单元格的行高和列宽。

 string FilePath = @"..\..\..\Sample Files\";

string FileName = FilePath + "Image Markers.xlsx";

//Get the image data.

byte[]imageData = File.ReadAllBytes(FilePath + "Aspose.Cells.png");

//Create a datatable.

DataTable t = new DataTable("Table1");

//Add a column to save pictures.

DataColumn dc = t.Columns.Add("Picture");

//Set its data type.

dc.DataType = typeof(object);

//Add a new new record to it.

DataRow row = t.NewRow();

row[0]= imageData;

t.Rows.Add(row);

//Add another record (having picture) to it.

//imageData = File.ReadAllBytes(FilePath + "Desert.jpg");

//row = t.NewRow();

//row[0]= imageData;

//t.Rows.Add(row);

//Create WorkbookDesigner object.

WorkbookDesigner designer = new WorkbookDesigner();

//Open the temple Excel file.

designer.Workbook = new Workbook(FileName);

//Set the datasource.

designer.SetDataSource(t);

//Process the markers.

designer.Process();

//Save the Excel file.

designer.Workbook.Save(FileName);
