Image quality poor in header when converting to pdf

If I place an image in a worksheet header and then save as pdf, the image quality is poor.

The same image placed in the body of a worksheet renders ok.

I am using the following code:

Workbook workbook = new Workbook(@“C:\temp\Book1.xlsx”);

workbook.Settings.CreateCalcChain = false;


workbook.Save(@“C:\temp\Test1.pdf”, SaveFormat.Pdf);

Is there any way to increase the quality of the image in a header?

Attached workbook and generated pdf.


Thanks for providing us sample code and template file.

After an initial test, I observed the issue as you mentioned by converting your template file to PDF file format, the image’s quality is poor in the header when
converting to PDF file format. I have logged a ticket with an id “CELLSNET-43198” for your issue. We will look into it soon.

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

Thank you.
