  • FME - why is tif writer is setting 0's in any band to NODATA?[ e.g. (0,16,0)>>(NODATA, 16, NODATA) ]
I'm reading a geotiff and am unsure why when I'm writing to a new geotif, all my dark dark green cells, such as RGB (0,16,0), get rewritten to (NODATA, 16, NODATA). 

 

 

Using the RasterBandNoDataRemover does fix the problem, but also changes the NODATA cells that I want to be NODATA into balck (0,0,0).

 

 

How can I fix this? Seems to me that this should not be a default behavior...

 

 

 

Hi, the RasterCellValueReplacer transformer might help you.

Hi,

 

 

 

Appearently 0 is nodata in your set.

 

RasterBandNodataSetter or replacer might be usefull.

 

 

After looking over all the options, the easiest options seems to be using RasterExpressionEvaluator.
