Using Transparent logo in Smartforms

Hi experts,

I need to use company Logo in PO. I uploaded the BMP file in SE78.

But the problem is that the White portion of the logo is turning Grey in the smartform.

For the alternative case i have uploaded the TIFF format logo using program RSTXLDMC.

And used Include text. But in print instead of LOGO hexadecimal values are coming.

Is there any solution to print the the logo with transparent background.

Thanx
