The word is renamed when converting to image

Hello team,

Thank you for your support.

PQ2366.zip (7.1 KB)
2.jpg (49.4 KB)

I have converted PQ2366.xls to image using Aspose 17.8 however an error has happened.
Please find error portion in 2.jpg.

  1. The word “系列1” has changed to “Series 1”

I have also attached PQ2366SaveAsPDFbyExcel.pdf which is a pdf MS Excel outputs correctly as a reference.

This is my code

public static List ConvertExcelToImage(string docName, MemoryStream docStream, Dictionary<string, string> config)
var pageInfoList = new List();

            // Get config setting
            string docRootDir = config["DocumentsFilePath"];
            int dpi = int.Parse(config["ImageDPI"]);
            int thumbMaxH = int.Parse(config["ThumbnailMaxHeight"]);
            int thumbMaxW = int.Parse(config["ThumbnailMaxWidth"]);
            int maxPageNum = int.Parse(config["DocumentMaxPageNum"]);
            double readScale = double.Parse(config["ImageReadScale"]);
            int readDpi = Convert.ToInt32(dpi * readScale);

            // Create images directory
            string pageImgDir = docRootDir;
            if (!Directory.Exists(pageImgDir))

            // Get the encoder of JPEG
            ImageCodecInfo jpgEncoder = GetCodecInfo();
            //EncoderParameters encParams = GetEncoderParams();

            EncoderParameters encParams = GetEncoderParams(int.Parse(config["ImageJpegQuality"]));

            // Instantiate the License class
            Aspose.Cells.License license = new Aspose.Cells.License();

            // Convert .doc and .docx file to PDF.
            Workbook book = new Workbook(docStream);

            //Define ImageOrPrintOptions
            ImageOrPrintOptions imgOptions = new ImageOrPrintOptions();
            //Specify the image format
            imgOptions.ImageFormat = ImageFormat.Png;
            imgOptions.VerticalResolution = readDpi;
            imgOptions.HorizontalResolution = readDpi;

            int totalPageCount = 0;
            foreach (Worksheet sheet in book.Worksheets)
                //Render the sheet with respect to specified image/print options
                SheetRender sr = new SheetRender(sheet, imgOptions);

                for (int i = 0; i < sr.PageCount; i++)

                    if (totalPageCount <= maxPageNum)
                        //Render the image for the sheet
                        string imgFile = string.Format("{0}_{1:D8}.jpg",
                                Path.GetFileNameWithoutExtension(docName), totalPageCount);
                        string imgPath = Path.Combine(pageImgDir, imgFile);
                        using (Bitmap bitmap = sr.ToImage(i))
                            // Export image file
                            bitmap.SetResolution(dpi, dpi);
                            bitmap.Save(imgPath, jpgEncoder, encParams);

                            // Add  PageInfo List

                if (totalPageCount >= maxPageNum) break;

            // return results with flag of max page limit over
            return pageInfoList;

They are parameters

            // Get config setting
               Create Appseting key value for async function
               Dictionary<string, string> config = new Dictionary<string, string>();

               config.Add("DocumentsFilePath", outDir);
               config.Add("ImageDPI", "96");
               config.Add("ImageReadScale", "1.25");
               config.Add("ThumbnailMaxHeight", "252");
               config.Add("ThumbnailMaxWidth", "210");
               config.Add("ImageJpegQuality", "80");
               config.Add("DocumentMaxPageNum", "1000");
