WritableRaster
```
public class Raster
extends Object
```
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.
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.
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.
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.
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.
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.
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.
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.
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.

```
    Creates a Raster based on a packed SampleModel with the specified data type, width, height, number of bands, and bits per band. If the number of bands is one, the SampleModel will be a MultiPixelPackedSampleModel.
    If the number of bands is more than one, the SampleModel will be a SinglePixelPackedSampleModel, with each band having bitsPerBand bits. In either case, the requirements on dataType and bitsPerBand imposed by the corresponding SampleModel must be met.
    The upper left corner of the Raster is given by the location argument. If location is null, (0, 0) will be used. The dataType parameter should be one of the enumerated values defined in the DataBuffer class.
    The only dataTypes supported currently are TYPE_BYTE, TYPE_USHORT, and TYPE_INT.
    
    Parameters:
    
    dataType - the data type for storing samples
    
    w - the width in pixels of the image data
    
    h - the height in pixels of the image data
    
    bands - the number of bands
    
    bitsPerBand - the number of bits per band
    
    location - the upper-left corner of the Raster
    
    Returns:
    
    a WritableRaster object with the specified data type, width, height, number of bands, and bits per band.
    
    Throws:
    
    RasterFormatException - if w or h is less than or equal to zero, or computing either location.x + w or location.y + h results in integer overflow
    
    IllegalArgumentException - if the product of bitsPerBand and bands is greater than the number of bits held by dataType
    
    IllegalArgumentException - if bitsPerBand or bands is not greater than zero
    
    IllegalArgumentException - if dataType is not one of the supported data types, which are DataBuffer.TYPE_BYTE, DataBuffer.TYPE_USHORT or DataBuffer.TYPE_INT

                          int[] bandList)
```
    Returns a new Raster which shares all or part of this Raster's DataBuffer. The new Raster will possess a reference to the current Raster, accessible through its getParent() method.
    The parentX, parentY, width and height parameters form a Rectangle in this Raster's coordinate space, indicating the area of pixels to be shared. An error will be thrown if this Rectangle is not contained with the bounds of the current Raster.
    The new Raster may additionally be translated to a different coordinate system for the plane than that used by the current Raster. The childMinX and childMinY parameters give the new (x, y) coordinate of the upper-left pixel of the returned Raster; the coordinate (childMinX, childMinY) in the new Raster will map to the same pixel as the coordinate (parentX, parentY) in the current Raster.
    The new Raster may be defined to contain only a subset of the bands of the current Raster, possibly reordered, by means of the bandList parameter. If bandList is null, it is taken to include all of the bands of the current Raster in their current order.
    To create a new Raster that contains a subregion of the current Raster, but shares its coordinate system and bands, this method should be called with childMinX equal to parentX, childMinY equal to parentY, and bandList equal to null.
    
    Parameters:
    
    parentX - The X coordinate of the upper-left corner in this Raster's coordinates
    
    parentY - The Y coordinate of the upper-left corner in this Raster's coordinates
    
    width - Width of the region starting at (parentX, parentY)
    
    height - Height of the region starting at (parentX, parentY).
    
    childMinX - The X coordinate of the upper-left corner of the returned Raster
    
    childMinY - The Y coordinate of the upper-left corner of the returned Raster
    
    bandList - Array of band indices, or null to use all bands
    
    Returns:
    
    a new Raster.
    
    Throws:
    
    RasterFormatException - if the specified subregion is outside of the raster bounds.
    
    RasterFormatException - if width or height is less than or equal to zero, or computing any of parentX + width, parentY + height, childMinX + width, or childMinY + height results in integer overflow

```
    Returns data for a single pixel in a primitive array of type TransferType. For image data supported by the Java 2D(tm) API, this will be one of DataBuffer.TYPE_BYTE, DataBuffer.TYPE_USHORT, DataBuffer.TYPE_INT, DataBuffer.TYPE_SHORT, DataBuffer.TYPE_FLOAT, or DataBuffer.TYPE_DOUBLE. Data may be returned in a packed format, thus increasing efficiency for data transfers. An ArrayIndexOutOfBoundsException may be thrown if the coordinates are not in bounds. However, explicit bounds checking is not guaranteed. A ClassCastException will be thrown if the input object is non null and references anything other than an array of TransferType.
    
    Parameters:
    
    x - The X coordinate of the pixel location
    
    y - The Y coordinate of the pixel location
    
    outData - An object reference to an array of type defined by getTransferType() and length getNumDataElements(). If null, an array of appropriate type and size will be allocated
    
    Returns:
    
    An object reference to an array of type defined by getTransferType() with the requested pixel data.
    
    Throws:
    
    ArrayIndexOutOfBoundsException - if the coordinates are not in bounds, or if outData is too small to hold the output.
