+/**
+ * This abstract class is used to serve as a color space tag to identify the
+ * specific color space of a Color object or, via a ColorModel object,
+ * of an Image, a BufferedImage, or a GraphicsDevice.  It contains
+ * methods that transform colors in a specific color space to/from sRGB
+ * and to/from a well-defined CIEXYZ color space.
+ * <p>
+ * For purposes of the methods in this class, colors are represented as
+ * arrays of color components represented as floats in a normalized range
+ * defined by each ColorSpace.  For many ColorSpaces (e.g. sRGB), this
+ * range is 0.0 to 1.0.  However, some ColorSpaces have components whose
+ * values have a different range.  Methods are provided to inquire per
+ * component minimum and maximum normalized values.
+ * <p>
+ * Several variables are defined for purposes of referring to color
+ * space types (e.g. TYPE_RGB, TYPE_XYZ, etc.) and to refer to specific
+ * color spaces (e.g. CS_sRGB and CS_CIEXYZ).
+ * sRGB is a proposed standard RGB color space.  For more information,
+ * see <A href="http://www.w3.org/pub/WWW/Graphics/Color/sRGB.html">
+ * http://www.w3.org/pub/WWW/Graphics/Color/sRGB.html
+ * </A>.
+ * <p>
+ * The purpose of the methods to transform to/from the well-defined
+ * CIEXYZ color space is to support conversions between any two color
+ * spaces at a reasonably high degree of accuracy.  It is expected that
+ * particular implementations of subclasses of ColorSpace (e.g.
+ * ICC_ColorSpace) will support high performance conversion based on
+ * underlying platform color management systems.
+ * <p>
+ * The CS_CIEXYZ space used by the toCIEXYZ/fromCIEXYZ methods can be
+ * described as follows:
+<pre>
+
+&nbsp;     CIEXYZ
+&nbsp;     viewing illuminance: 200 lux
+&nbsp;     viewing white point: CIE D50
+&nbsp;     media white point: "that of a perfectly reflecting diffuser" -- D50
+&nbsp;     media black point: 0 lux or 0 Reflectance
+&nbsp;     flare: 1 percent
+&nbsp;     surround: 20percent of the media white point
+&nbsp;     media description: reflection print (i.e., RLAB, Hunt viewing media)
+&nbsp;     note: For developers creating an ICC profile for this conversion
+&nbsp;           space, the following is applicable.  Use a simple Von Kries
+&nbsp;           white point adaptation folded into the 3X3 matrix parameters
+&nbsp;           and fold the flare and surround effects into the three
+&nbsp;           one-dimensional lookup tables (assuming one uses the minimal
+&nbsp;           model for monitors).

+/**
+ * A representation of color profile data for device independent and
+ * device dependent color spaces based on the International Color
+ * Consortium Specification ICC.1:2001-12, File Format for Color Profiles,
+ * (see <A href="http://www.color.org"> http://www.color.org</A>).
+ * <p>
+ * An ICC_ColorSpace object can be constructed from an appropriate
+ * ICC_Profile.
+ * Typically, an ICC_ColorSpace would be associated with an ICC
+ * Profile which is either an input, display, or output profile (see
+ * the ICC specification).  There are also device link, abstract,
+ * color space conversion, and named color profiles.  These are less
+ * useful for tagging a color or image, but are useful for other
+ * purposes (in particular device link profiles can provide improved
+ * performance for converting from one device's color space to
+ * another's).
+ * <p>
+ * ICC Profiles represent transformations from the color space of
+ * the profile (e.g. a monitor) to a Profile Connection Space (PCS).
+ * Profiles of interest for tagging images or colors have a PCS
+ * which is one of the two specific device independent
+ * spaces (one CIEXYZ space and one CIELab space) defined in the
+ * ICC Profile Format Specification.  Most profiles of interest
+ * either have invertible transformations or explicitly specify
+ * transformations going both directions.

+/**
+ *  This class represents image data which is stored in a band interleaved
+ *  fashion and for
+ *  which each sample of a pixel occupies one data element of the DataBuffer.
+ *  It subclasses ComponentSampleModel but provides a more efficent
+ *  implementation for accessing band interleaved image data than is provided
+ *  by ComponentSampleModel.  This class should typically be used when working
+ *  with images which store sample data for each band in a different bank of the
+ *  DataBuffer. Accessor methods are provided so that image data can be
+ *  manipulated directly. Pixel stride is the number of
+ *  data array elements between two samples for the same band on the same
+ *  scanline. The pixel stride for a BandedSampleModel is one.
+ *  Scanline stride is the number of data array elements between
+ *  a given sample and the corresponding sample in the same column of the next
+ *  scanline.  Band offsets denote the number
+ *  of data array elements from the first data array element of the bank
+ *  of the DataBuffer holding each band to the first sample of the band.
+ *  The bands are numbered from 0 to N-1.
+ *  Bank indices denote the correspondence between a bank of the data buffer
+ *  and a band of image data.  This class supports
+ *  {@link DataBuffer#TYPE_BYTE TYPE_BYTE},
+ *  {@link DataBuffer#TYPE_USHORT TYPE_USHORT},
+ *  {@link DataBuffer#TYPE_SHORT TYPE_SHORT},
+ *  {@link DataBuffer#TYPE_INT TYPE_INT},
+ *  {@link DataBuffer#TYPE_FLOAT TYPE_FLOAT}, and

+ *  for the same band on the same scanline. Scanline stride is the number
+ *  of data array elements between a given sample and the corresponding sample
+ *  in the same column of the next scanline.  Band offsets denote the number
+ *  of data array elements from the first data array element of the bank
+ *  of the DataBuffer holding each band to the first sample of the band.
+ *  The bands are numbered from 0 to N-1.  This class can represent image
+ *  data for which each sample is an unsigned integral number which can be
+ *  stored in 8, 16, or 32 bits (using <code>DataBuffer.TYPE_BYTE</code>,
+ *  <code>DataBuffer.TYPE_USHORT</code>, or <code>DataBuffer.TYPE_INT</code>,
+ *  respectively), data for which each sample is a signed integral number
+ *  which can be stored in 16 bits (using <code>DataBuffer.TYPE_SHORT</code>),
+ *  or data for which each sample is a signed float or double quantity
+ *  (using <code>DataBuffer.TYPE_FLOAT</code> or
+ *  <code>DataBuffer.TYPE_DOUBLE</code>, respectively).
+ *  All samples of a given ComponentSampleModel
+ *  are stored with the same precision.  All strides and offsets must be
+ *  non-negative.  This class supports
+ *  {@link DataBuffer#TYPE_BYTE TYPE_BYTE},
+ *  {@link DataBuffer#TYPE_USHORT TYPE_USHORT},
+ *  {@link DataBuffer#TYPE_SHORT TYPE_SHORT},
+ *  {@link DataBuffer#TYPE_INT TYPE_INT},

+/**
+ * This class exists to wrap one or more data arrays.  Each data array in
+ * the DataBuffer is referred to as a bank.  Accessor methods for getting
+ * and setting elements of the DataBuffer's banks exist with and without
+ * a bank specifier.  The methods without a bank specifier use the default 0th
+ * bank.  The DataBuffer can optionally take an offset per bank, so that
+ * data in an existing array can be used even if the interesting data
+ * doesn't start at array location zero.  Getting or setting the 0th
+ * element of a bank, uses the (0+offset)th element of the array.  The
+ * size field specifies how much of the data array is available for
+ * use.  Size + offset for a given bank should never be greater
+ * than the length of the associated data array.  The data type of
+ * a data buffer indicates the type of the data array(s) and may also
+ * indicate additional semantics, e.g. storing unsigned 8-bit data
+ * in elements of a byte array.  The data type may be TYPE_UNDEFINED
+ * or one of the types defined below.  Other types may be added in
+ * the future.  Generally, an object of class DataBuffer will be cast down
+ * to one of its data type specific subclasses to access data type specific
+ * methods for improved performance.  Currently, the Java 2D(tm) API
+ * image classes use TYPE_BYTE, TYPE_USHORT, TYPE_INT, TYPE_SHORT,
+ * TYPE_FLOAT, and TYPE_DOUBLE DataBuffers to store image data.

+/**
+ * The <code>MultiPixelPackedSampleModel</code> class represents
+ * one-banded images and can pack multiple one-sample
+ * pixels into one data element.  Pixels are not allowed to span data elements.
+ * The data type can be DataBuffer.TYPE_BYTE, DataBuffer.TYPE_USHORT,
+ * or DataBuffer.TYPE_INT.  Each pixel must be a power of 2 number of bits
+ * and a power of 2 number of pixels must fit exactly in one data element.
+ * Pixel bit stride is equal to the number of bits per pixel.  Scanline
+ * stride is in data elements and the last several data elements might be
+ * padded with unused pixels.  Data bit offset is the offset in bits from
+ * the beginning of the {@link DataBuffer} to the first pixel and must be
+ * a multiple of pixel bit stride.
+ * <p>
+ * The following code illustrates extracting the bits for pixel
+ * <code>x,&nbsp;y</code> from <code>DataBuffer</code> <code>data</code>
+ * and storing the pixel data in data elements of type
+ * <code>dataType</code>:
+ * <pre>
+ *      int dataElementSize = DataBuffer.getDataTypeSize(dataType);
+ *      int bitnum = dataBitOffset + x*pixelBitStride;
+ *      int element = data.getElem(y*scanlineStride + bitnum/dataElementSize);
+ *      int shift = dataElementSize - (bitnum & (dataElementSize-1))
+ *                  - pixelBitStride;
+ *      int pixel = (element >> shift) & ((1 << pixelBitStride) - 1);
+ * </pre>

+/**
+ * A class representing a rectangular array of pixels.  A Raster
+ * encapsulates a DataBuffer that stores the sample values and a
+ * SampleModel that describes how to locate a given sample value in a
+ * DataBuffer.
+ * <p>
+ * A Raster defines values for pixels occupying a particular
+ * rectangular area of the plane, not necessarily including (0, 0).
+ * The rectangle, known as the Raster's bounding rectangle and
+ * available by means of the getBounds method, is defined by minX,
+ * minY, width, and height values.  The minX and minY values define
+ * the coordinate of the upper left corner of the Raster.  References
+ * to pixels outside of the bounding rectangle may result in an
+ * exception being thrown, or may result in references to unintended
+ * elements of the Raster's associated DataBuffer.  It is the user's
+ * responsibility to avoid accessing such pixels.
+ * <p>
+ * A SampleModel describes how samples of a Raster
+ * are stored in the primitive array elements of a DataBuffer.
+ * Samples may be stored one per data element, as in a
+ * PixelInterleavedSampleModel or BandedSampleModel, or packed several to
+ * an element, as in a SinglePixelPackedSampleModel or
+ * MultiPixelPackedSampleModel.  The SampleModel is also
+ * controls whether samples are sign extended, allowing unsigned
+ * data to be stored in signed Java data types such as byte, short, and
+ * int.
+ * <p>
+ * Although a Raster may live anywhere in the plane, a SampleModel
+ * makes use of a simple coordinate system that starts at (0, 0).  A
+ * Raster therefore contains a translation factor that allows pixel
+ * locations to be mapped between the Raster's coordinate system and
+ * that of the SampleModel.  The translation from the SampleModel
+ * coordinate system to that of the Raster may be obtained by the
+ * getSampleModelTranslateX and getSampleModelTranslateY methods.
+ * <p>
+ * A Raster may share a DataBuffer with another Raster either by
+ * explicit construction or by the use of the createChild and
+ * createTranslatedChild methods.  Rasters created by these methods
+ * can return a reference to the Raster they were created from by
+ * means of the getParent method.  For a Raster that was not
+ * constructed by means of a call to createTranslatedChild or
+ * createChild, getParent will return null.
+ * <p>
+ * The createTranslatedChild method returns a new Raster that
+ * shares all of the data of the current Raster, but occupies a
+ * bounding rectangle of the same width and height but with a
+ * different starting point.  For example, if the parent Raster
+ * occupied the region (10, 10) to (100, 100), and the translated
+ * Raster was defined to start at (50, 50), then pixel (20, 20) of the
+ * parent and pixel (60, 60) of the child occupy the same location in
+ * the DataBuffer shared by the two Rasters.  In the first case, (-10,
+ * -10) should be added to a pixel coordinate to obtain the
+ * corresponding SampleModel coordinate, and in the second case (-50,
+ * -50) should be added.
+ * <p>
+ * The translation between a parent and child Raster may be
+ * determined by subtracting the child's sampleModelTranslateX and
+ * sampleModelTranslateY values from those of the parent.
+ * <p>
+ * The createChild method may be used to create a new Raster
+ * occupying only a subset of its parent's bounding rectangle
+ * (with the same or a translated coordinate system) or
+ * with a subset of the bands of its parent.
+ * <p>
+ * All constructors are protected.  The correct way to create a
+ * Raster is to use one of the static create methods defined in this
+ * class.  These methods create instances of Raster that use the
+ * standard Interleaved, Banded, and Packed SampleModels and that may
+ * be processed more efficiently than a Raster created by combining
+ * an externally generated SampleModel and DataBuffer.

+/**
+ *  This abstract class defines an interface for extracting samples of pixels
+ *  in an image.  All image data is expressed as a collection of pixels.
+ *  Each pixel consists of a number of samples. A sample is a datum
+ *  for one band of an image and a band consists of all samples of a
+ *  particular type in an image.  For example, a pixel might contain
+ *  three samples representing its red, green and blue components.
+ *  There are three bands in the image containing this pixel.  One band
+ *  consists of all the red samples from all pixels in the
+ *  image.  The second band consists of all the green samples and
+ *  the remaining band consists of all of the blue samples.  The pixel
+ *  can be stored in various formats.  For example, all samples from
+ *  a particular band can be stored contiguously or all samples from a
+ *  single pixel can be stored contiguously.
+ *  <p>
+ *  Subclasses of SampleModel specify the types of samples they can
+ *  represent (e.g. unsigned 8-bit byte, signed 16-bit short, etc.)
+ *  and may specify how the samples are organized in memory.
+ *  In the Java 2D(tm) API, built-in image processing operators may
+ *  not operate on all possible sample types, but generally will work
+ *  for unsigned integral samples of 16 bits or less.  Some operators
+ *  support a wider variety of sample types.
+ *  <p>
+ *  A collection of pixels is represented as a Raster, which consists of
+ *  a DataBuffer and a SampleModel.  The SampleModel allows access to
+ *  samples in the DataBuffer and may provide low-level information that
+ *  a programmer can use to directly manipulate samples and pixels in the
+ *  DataBuffer.
+ *  <p>
+ *  This class is generally a fall back method for dealing with
+ *  images.  More efficient code will cast the SampleModel to the
+ *  appropriate subclass and extract the information needed to directly
+ *  manipulate pixels in the DataBuffer.

+ * independent of any specific rendering of the image.  For example, a
+ * RenderableImage can be rotated and cropped in
+ * resolution-independent terms.  Then, it can be rendered for various
+ * specific contexts, such as a draft preview, a high-quality screen
+ * display, or a printer, each in an optimal fashion.
+ *
+ * <p> A RenderedImage is returned from a RenderableImage via the
+ * createRendering() method, which takes a RenderContext.  The
+ * RenderContext specifies how the RenderedImage should be
+ * constructed.  Note that it is not possible to extract pixels
+ * directly from a RenderableImage.

+     * See the if (fm) {} cases in the code.
+     * For the non-FM case, we not only save 3 bytes per row, but this
