Another question from me.

 

 

I know that FME is capable of setting no data on geotiffs when making a conversion from polygon to raster. Setting a background value with the ImageRasterizer and then filling it with Nodata. Interpreting this image in ArcGIS, the Nodata actually means no data and can be excluded from calculations. 

 

 

I want to do the same process process manually without the conversion from a polygon. So GeoTiff --> GeoTiff.

 

 

The RasterBandNodataSetter doesn't seem to actually work for me what should I fill in for "Nodata Value" when for instance I want all the 255,255,255 values to be regarded as NoData? To what attribute should it be linked? Any alternatives? I prefer not to make a conversion to shape first, if possible.

Wow. I just had to put a value 0 there and not link it to an attribute. Ok, nevermind, delete. Found it, thanks!
