I've tried using the RasterBandNoDataSetter, and then I tried putting a RasterBandNodataRemover in front of it, and then I tried putting a RasterSelector in front of that, but all to no effect.
I don't want to change the data in any way, just flag that 255 is noData.
This seems like it should be simple; what am I doing wrong?
Thanks,
Jonathan

+18Thanks. Is this an FME specific thing or a format thing?
I can use ArcGIS to create a JP2 file that has noData. Unfortunately it can't export ECW so I can't test that.

A format thing, could be that the 'nodata' in ESRi is an internal thing too.
