基于单元格引用插入图片

有时您会有一张空白图片，并且需要通过在公式栏中设置单元格引用来显示图片中的数据或内容。Aspose.Cells支持此功能（Microsoft Excel 2010）。

根据单元格引用插入图片

Aspose.Cells支持将工作表单元格的内容显示在图像形状中。您可以将图片链接到包含要显示的数据的单元格。由于单元格或单元格范围与图形对象相关联，因此对该单元格或单元格范围中数据的更改会自动出现在图形对象中。通过调用ShapeCollection集合（封装在Worksheet对象中）的AddPicture方法向工作表中添加图片。使用Formula对象的属性指定单元格范围。

代码示例

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
// Instantiate a new Workbook
Workbook workbook = new Workbook();
// Get the first worksheet's cells collection
Cells cells = workbook.Worksheets[0].Cells;

// Add string values to the cells
cells["A1"].PutValue("A1");
cells["C10"].PutValue("C10");

// Get the conditional icon's image data
byte[] imagedata = ConditionalFormattingIcon.GetIconImageData(IconSetType.TrafficLights31, 0);
// Create a stream based on the image data
MemoryStream stream = new MemoryStream(imagedata);

// Add a blank picture to the D1 cell
Picture pic = (Picture)workbook.Worksheets[0].Shapes.AddPicture(0, 3, stream, 10, 10);
// Specify the formula that refers to the source range of cells
pic.Formula = "A1:C10";
// Update the shapes selected value in the worksheet
workbook.Worksheets[0].Shapes.UpdateSelectedValue();

// Save the Excel file.
workbook.Save(dataDir + "referencedpicture.out.xlsx");
