Excel转pdf，图像质量不好？

Question

OK, I have Excel(from Excel 2010 Workbook Template) sheet with picture on it and when I export this sheet to pdf i get very bad image quality. Text is fine, but image not at all.

I use this code to export excel to pdf:

xlSS.ExportAsFixedFormat(
    XlFixedFormatType.xlTypePDF, 
    path, 
    XlFixedFormatQuality.xlQualityStandard);

Is there better way to save(export) .xlsx/.xls to .pdf so I could get nice image quality?

Here is comparation, the first one is when extracted to pdf:

Solved. Solution is that you have to resize picture after its insert in sheet, otherwise it looses quality.

I've done it like that and maintained image quality even when exporting sheet into pdf file.
