Lines have disappeared when converting images

Hello team,

I have converted 0_32.docx to Images with Aspose.Words. Please find error point with 0_32_00000001.jpg.

  • The lines have disappeared (Page 1)

This is my code.

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

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 < 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 config = new Dictionary();

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,

Hi there,

Thanks for your patience. It is to inform you that the issue which you are facing is actually not a bug in Aspose.Words. So, we have closed this issue (WORDSNET-15391) as ‘Not a Bug’.

Please use Graphics.SmoothingMode as SmoothingMode.AntiAlias to get the desired output. We have attached the output BMP file with this post for your kind reference.
17.6.zip (9.0 KB)

using (Graphics graphics = Graphics.FromImage(bitmap))
    graphics.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;
    document.RenderToScale(0, graphics, 0, 0, 1.25f);

    bitmap.Save(MyDir + "17.6.bmp");
