} 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. |

SampleModel to that of the Raster. To convert a pixel's X
coordinate from the Raster coordinate system to the SampleModel
coordinate system, this value must be subtracted. |
public final int getSampleModelTranslateY() {
return sampleModelTranslateY;
} Returns the Y translation from the coordinate system of the
SampleModel to that of the Raster. To convert a pixel's Y
coordinate from the Raster coordinate system to the SampleModel
coordinate system, this value must be subtracted. |
public int[] getSamples(int x,
int y,
int w,
int h,
int b,
int[] iArray) {
return sampleModel.getSamples(x - sampleModelTranslateX,
y - sampleModelTranslateY,
w, h, b, iArray,
dataBuffer);
} Returns the samples for a specified band for the specified rectangle
of pixels in an int array, one sample per array element.
An ArrayIndexOutOfBoundsException may be thrown
if the coordinates are not in bounds. However, explicit bounds
checking is not guaranteed. |
public float[] getSamples(int x,
int y,
int w,
int h,
int b,
float[] fArray) {
return sampleModel.getSamples(x - sampleModelTranslateX,
y - sampleModelTranslateY,
w, h, b, fArray, dataBuffer);
} Returns the samples for a specified band for the specified rectangle
of pixels in a float array, one sample per array element.
An ArrayIndexOutOfBoundsException may be thrown
if the coordinates are not in bounds. However, explicit bounds
checking is not guaranteed. |
public double[] getSamples(int x,
int y,
int w,
int h,
int b,
double[] dArray) {
return sampleModel.getSamples(x - sampleModelTranslateX,
y - sampleModelTranslateY,
w, h, b, dArray, dataBuffer);
} Returns the samples for a specified band for a specified rectangle
of pixels in a double array, one sample per array element.
An ArrayIndexOutOfBoundsException may be thrown
if the coordinates are not in bounds. However, explicit bounds
checking is not guaranteed. |
public final int getTransferType() {
return sampleModel.getTransferType();
} Returns the TransferType used to transfer pixels via the
getDataElements and setDataElements methods. When pixels
are transferred via these methods, they may be transferred in a
packed or unpacked format, depending on the implementation of the
underlying SampleModel. Using these methods, pixels are transferred
as an array of getNumDataElements() elements of a primitive type given
by getTransferType(). The TransferType may or may not be the same
as the storage data type of the DataBuffer. The TransferType will
be one of the types defined in DataBuffer. |
public final int getWidth() {
return width;
} Returns the width in pixels of the Raster. |
