question: public WritableRaster createCompatibleWritableRaster ( int w , int h ) { int [ ] bOffs = { 2 , 1 , 0 } ; return Raster . createInterleavedRaster ( DataBuffer . TYPE_BYTE , w , h , w * 3 , 3 , bOffs , null ) ; }
target:  Creates a WritableRaster with the specified width and height, that has a data layout (SampleModel) compatible with this ColorModel.
