Characters overlap with line when convertng to image

Hello team,

I have converted PQ3766.docx to Images with Aspose.Words however I got 1 error… (21.3 KB)
1.jpg (46.0 KB)

  1. Characters overlap with line.

I have also attached PQ3766SaveAsPdfByWord.pdf which is a pdf MS Word outputs correctly as a reference.
PQ3766SaveAsPdfByWord.pdf (182.8 KB)

This is my code.

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

        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"]);
        float readScale = float.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.Words.License license = new Aspose.Words.License();

        // Convert .doc and .docx file to PDF.
        Document document = new Document(docStream);

        for (int i = 0; (i < document.PageCount) && (i < maxPageNum); i++)
            var pageInfo = document.GetPageInfo(i);
            Size pixelSize = pageInfo.GetSizeInPixels(1.0f, readDpi);

            // Export image file
            string imgFile = string.Format("{0}_{1:D8}.jpg",
                    Path.GetFileNameWithoutExtension(docName), i + 1);
            string imgPath = Path.Combine(pageImgDir, imgFile);
            using (Bitmap bitmap = new Bitmap(pixelSize.Width, pixelSize.Height))
                bitmap.SetResolution(dpi, dpi);

                using (Graphics graphics = Graphics.FromImage(bitmap))
                    document.RenderToScale(i, graphics, 0, 0, readScale);

                    bitmap.Save(imgPath, jpgEncoder, encParams);

            // TODO Create OCR XML

            // Add  PageInfo List

        // 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");

Thank you,
