AX2012 引用NOPI 添加图片到EXCEL

void AddPieChart(int rowNum = 4)
{
    System.Byte[]    bytes;
    fileName                    _fileName;
    NPOI.HSSF.UserModel.HSSFPatriarch   patriarch;
    NPOI.HSSF.UserModel.HSSFClientAnchor  anchor;
    NPOI.HSSF.UserModel.HSSFPicture  pict;
    int                 png;
    _fileName =@"C:\lmlogo.png";
    if(_fileName)
    bytes = System.IO.File::ReadAllBytes(_fileName);
    if (bytes)
    {

        png = hssfworkbook.AddPicture(bytes,NPOI.SS.UserModel.PictureType::PNG);

        patriarch = sheet.CreateDrawingPatriarch();
        anchor    = new NPOI.HSSF.UserModel.HSSFClientAnchor( 0, 0, 1000, 0, 0, 0 , rowNum, 1);
        //##处理照片位置，【图片左上角为（col, row）第row+1行col+1列，右下角为（ col +1, row +1）第 col +1+1行row +1+1列，宽为100，高为50
        pict = patriarch.CreatePicture(anchor, png);

        // pict.Resize();这句话一定不要，这是用图片原始大小来显示
    }
