OpenXml: Determining the Image in a Cell in Excel [duplicate]

Answer 1

The trick is to get the relationship id "rId" of the image. You get that by getting the TwoCellAnchor of the row/col in question. Then get the Embed. Use that to get the image.

    [Test]
    public void GetImageRelationshipIdAndImageOfThatId()
    {
        string row = "1";
        string col = "0";

        WorkbookPart wbPart = document.WorkbookPart;
        var workSheet = wbPart.WorksheetParts.FirstOrDefault();

        TwoCellAnchor cellHoldingPicture = workSheet.DrawingsPart.WorksheetDrawing.OfType()
             .Where(c => c.FromMarker.RowId.Text == row && 
                    c.FromMarker.ColumnId.Text == col).FirstOrDefault();

        var picture = cellHoldingPicture.OfType().FirstOrDefault();
        string rIdofPicture = picture.BlipFill.Blip.Embed;

        Console.WriteLine("The rID of this Anchor's [{0},{1}] Picture is '{2}'" ,row,col, rIdofPicture);

        ImagePart imageInThisCell = (ImagePart)workSheet.DrawingsPart.GetPartById(rIdofPicture);

    }
