I am trying to convert PNGs with transparency to JPG, but the transparency is always black. I woudl like ti to be white. I have tried the -transpcolor option but I didn't do anything.

If it possible to set the transparency color converting to JPG?
Is this syntax correct?

... -out jpeg -transpcolor 255 255 255 -keepcspace -q 100 ...

You can't change the transparency color when saving in jpeg
