I need to extract from a raster imagery (Geotiff ) only the pixel with a specific range of values

I mean I need to return points that corresponding to the pixels with these values

Red between 245-255

Green between 245-255

Blue between 245-255

I would use a RasterCellValueReplacer to replace values <245 with 0, and then a RasterBandNoDataSetter (0) followed by a RasterCellCoercer with extract NoData set to no.

Great solution.
