Hello,

how is it possible to have nodata in white?

Thanks

Marion

Which raster format are you writing to?

Nodata has no colour, as such, it's just a placeholder for "there's nothing here", or NULL in database terminology.

But depending on which program you use to look at the raster, you can tell it to render the nodata cells as a particular colour, e.g. white or black are common choices. But this is usually somthing you do in the client program, not in FME.
