Image with smart markers


I’m currently trying to insert an image using smart markers (at the end I want to generate a PDF file).
Is it possible to insert an image with another overload of the method : public void SetDataSource(DataTable dataTable) ?
Instead I would like to use the overload :
SetDataSource(string variable, object data).
The type of data should be an array of bytes.
But I get an exception when I processed the WorkbookDesigner : “Index was outside the bounds of the array”.

Do you have any idea about this issue?


Kind Regards


Please create a databable and populate it with your image bytes on runtime and then use SetDataSource(DataTable dataTable)

For code example, please see this article, it has a code example that creates datatabe from the image bytes.


I already saw the example about images with Smart Markers, but I would like to not use Datatable object to just insert an image in the template.



This is a New Feature Request.

We have added this in our database. We will look into them and once it is implemented or we have some update relating to it, we will let you know asap.

This issue has been logged as CELLSNET-40291.


Please see the following code, it shows how to add image using the bytes.

I have attached the output xlsx file and the image used in this code.

Please also see the screenshot attached by me.


Workbook workbook = new Workbook();


WorkbookDesigner designer = new WorkbookDesigner();

designer.Workbook = workbook;

byte[] imageData = File.ReadAllBytes(@“C:\image.jpg”);

byte[][] data = new byte[1][];

data[0] = imageData;

designer.SetDataSource(“Variable”, data);



Thank you, it works now.
We have to use the type byte[][] instead of byte[] to make it work.

Why it’s not work for vb.net
Here my code below:
Dim FilePath As String = “…\Sample Files”

Dim FileName As String = FilePath & “Image Markers.xlsx”

'Get the image data.

Dim imageData() As Byte = File.ReadAllBytes(FilePath & “Aspose.Cells.png”)

'Create a datatable.

Dim t As New DataTable(“Table1”)

'Add a column to save pictures.

Dim dc As DataColumn = t.Columns.Add(“Picture”)

'Set its data type.

dc.DataType = GetType(Object)

'Add a new new record to it.

Dim row As DataRow = t.NewRow()

row(0) = imageData


But it’s not work. only show:System.Byte[] in Picture coloumn


Could you please zip and attach a standalone console application with sample files to reproduce the issue on our end, we will check it soon.

PS. please exclude Aspose.Cells.Dll to minimize the size of the zipped archive.

I find the problem is my version of Aspose.Cells.Dll is old. After I upgraded, it works. But another problem is the Picture: FitToCell not working. Attached the file please checkCsharpaspose图片.7z (217.6 KB)


I could not extract your zipped archive, it seems corrupted or versioning issue. Could you re-zip your resource file(s) with .zip extension and re-attach the zipped archive. We will check your issue soon.
