-/**
- * RescaleOp is a filter that changes each pixel by a scaling factor and offset.
- *
- * For filtering Rasters, either one scaling factor and offset can be specified,
- * which will be applied to all bands; or a scaling factor and offset can be
- * specified for each band.
- *
- * For BufferedImages, the scaling may apply to both color and alpha components.
- * If only one scaling factor is provided, or if the number of factors provided
- * equals the number of color components, the scaling is performed on all color
- * components. Otherwise, the scaling is performed on all components including
- * alpha. Alpha premultiplication is ignored.
- *
- * After filtering, if color conversion is necessary, the conversion happens,
- * taking alpha premultiplication into account.
