Aspose.cells convert workbook to .pdf - problem

I’m trying to convert the excel sheet with page setup into pdf.
I put an image with format pictures (brightness: 80%, contrast: 70%) in the header.
But after convert to pdf, the brightness and contrast of image has reset.
How can i keep the brightness and contrast when convert to pdf?
