Excel to PDF rendering - Poor quality image

Hello,

I want to convert an excel file to a pdf file. The code is like this :
Workbook workbook = new Workbook(inputPath);
PdfSaveOptions options = new PdfSaveOptions(SaveFormat.Pdf);
workbook.Save(dataDir + “output.pdf”, options);
Here we can see the original document in excel
quality.PNG (59.0 KB)
And here we can see the document exported to pdf with excel
qualityexceltopdf.PNG (34.1 KB)
Here we can see the document export to pdf with aspose
qualityref.PNG (30.0 KB)
We can see that there is a margin, so the images are more little and there is a black line on the image.

Thank you,

Do you have the same code ?

PdfSaveOptions options = new PdfSaveOptions(SaveFormat.Pdf);
workbook.Save(dataDir + “output.pdf”, options);

@helena.adi,
I have used the same code with latest version. Please upgrade and share your feedback while comparing our output PDF with Excel created PDF.

I forgot something explaining my problem.
Just before to convert the excel file into pdf file with aspose. I use this function
Shapes.UpdateSelectedValue();
For every sheet of the workbook. Even if, I change any cell value in my excel file, I can see the black line on the image and the margin at the bottom of the header.

@helena.adi,
We have observed the line on the image as shown in the following image. Upper image is of the PDF file generated by MS Excel whereas lower picture is of the PDF generated by Aspose.Cells. Please confirm it.

Regarding the second issue of margin at the bottom of header, I am afraid that it is not observed. Could you please identify it in the this image?
