i am doing a webform in ASP.NET and currently working with ClosedXML,is there a way to insert an image inside a worksheet in a position?, i have this code
Dim wb As New XLWorkbook()
Dim ws As IXLWorksheet = wb.Worksheets.Add("NAME")
Dim httpResponse = Response
httpResponse.Clear()
httpResponse.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"
'INSERT IMAGE HERE'
ws.insertimage("imagepath")'???
Dim namedoc As String = "namedoc"
httpResponse.AddHeader("content-disposition", "attachment;filename=""" + namedoc+ ".xlsx""")
Using tmpMemoryStream As MemoryStream = New MemoryStream()
wb.SaveAs(tmpMemoryStream)
tmpMemoryStream.WriteTo(httpResponse.OutputStream)
tmpMemoryStream.Close()
End Using
httpResponse.End()
Update: ClosedXML now supports images, see here .
Original answer:
How can I insert an image?
You can't. Although you can open an Excel that already has an image and save it preserving the image, you can't insert a new image with ClosedXML.
As Raidri says, I don't think you can.
But I got it working using Open XML using this, although it's not exactly straightforward:
