Shape of parentheses when converting image

Hello team,



I have converted 0_35.xlsx to a image with Aspose.Cells. Please find error points with 0_35_00000001.jpg.

- Shape of parentheses.



This is my code.

--------------------

public static List ConvertExcelToImage(string docName, MemoryStream docStream, Dictionary config)

{

try

{

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))

Directory.CreateDirectory(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();

license.SetLicense(“Aspose.Total.lic”);



// 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
{

totalPageCount++;



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);



// Export thumbnail file

//string thumbFilename = string.Format(@"{0}_thumb.jpg", Path.GetFileNameWithoutExtension(imgPath));

//string thumbPath = Path.Combine(Path.GetDirectoryName(imgPath), thumbFilename);

//float scale = (float)Math.Min((double)thumbMaxW / bitmap.Width, (double)thumbMaxH / bitmap.Height);

//int thumbW = System.Convert.ToInt32(bitmap.Width * scale);

//int thumbH = System.Convert.ToInt32(bitmap.Height * scale);

//using (Bitmap thumbBmp = new Bitmap(thumbW, thumbH))

//{

// thumbBmp.SetResolution(dpi, dpi);



// using (Graphics graph = Graphics.FromImage(thumbBmp))

// {

// graph.DrawImage(bitmap, 0, 0, thumbW, thumbH);

// }

// thumbBmp.Save(thumbPath, jpgEncoder, encParams);

//}



// TODO Create OCR XML



// Add PageInfo List

pageInfoList.Add(imgPath);

}

}

else

{

break;

}

}



if (totalPageCount >= maxPageNum) break;

}



// return results with flag of max page limit over

return pageInfoList;

}

finally

{

}

}

-------------

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”);

Hi,


Please try our latest version/fix: Aspose.Cells for .NET v17.5.2 (attached).

I have tested your scenario/ case a bit using the simplest lines of code to convert the shape (in the template file) to image file, it works ok, see the attached output image for your reference:
e.g
Sample code:

int readDpi = Convert.ToInt32(96 * 1.25);<o:p></o:p>

Workbook book = new Workbook("e:\\test2\\0_35.xlsx");

Worksheet sheet = book.Worksheets[0];

//Define ImageOrPrintOptions

ImageOrPrintOptions imgOptions = new ImageOrPrintOptions();

//Specify the image format

imgOptions.ImageFormat = ImageFormat.Png;

imgOptions.VerticalResolution = readDpi;

imgOptions.HorizontalResolution = readDpi;


sheet.Shapes[0].ToImage(“e:\test2\out1.png”,
imgOptions);



In case you still find the issue with the latest version/fix, kindly do post us details with sample code (runnable) and screenshot, we will check it soon.

Thank you.

Hello team,



Thank you for your support



I have tried 17.5.2 however it doesn’t work in my environment. I have attached jpg.

The phenomenon also happens in case of converting to PDF. I have attached pdf.





e.g sample for converting pdf.

----

// Instantiate the License class

Aspose.Cells.License license = new Aspose.Cells.License();

license.SetLicense(“Aspose.Total.lic”);



// Convert .xls and .xlsx file to PDF.

Workbook book = new Workbook(docStream);

book.Save(pdfStream, Aspose.Cells.SaveFormat.Pdf);

----

Hi,


Thanks for providing us sample files and sample code.

I am able to reproduce the issue as you mentioned by converting your template file to PDF/image. I found that the shape of parentheses is rendered wrong in output PDF/image. The issue is logged as:
  • CELLSNET-45389 - Shape of parentheses is rendered wrong in output PDF/image

Our concerned developer from product team will evaluate your issue soon.

Once we have an update on it, we will let you know here.

Thank you.
