Hi

What is the correct nconvert command line parameter to convert a 32bit PNG with Alpha to a JPEG, so that the Alpha channel is merged but the background is not black (as recent)?

in XnView it works when converting 32bit PNG to 24bit the background is set to white, but not in nconvert

thanks for your help

Rajko

-bgcolor 255 255 255 -canvas 100% 100% center

Use -transpcolor 255 255 255 -merge_alpha
