/**
* This class uses an affine transform to perform a linear mapping from
* 2D coordinates in the source image or {@code Raster} to 2D coordinates
* in the destination image or {@code Raster}.
* The type of interpolation that is used is specified through a constructor,
* either by a {@code RenderingHints} object or by one of the integer
* interpolation types defined in this class.
* <p>
* If a {@code RenderingHints} object is specified in the constructor, the
* interpolation hint and the rendering quality hint are used to set
* the interpolation type for this operation. The color rendering hint
* and the dithering hint can be used when color conversion is required.
* <p>
* Note that the following constraints have to be met:
* <ul>
* <li>The source and destination must be different.
* <li>For {@code Raster} objects, the number of bands in the source must
* be equal to the number of bands in the destination.
