This class represents image data which is stored in a pixel 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 pixel interleaved image data than is provided
by ComponentSampleModel. This class
stores sample data for all bands in a single 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. 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
TYPE_BYTE
,
TYPE_USHORT
,
TYPE_SHORT
,
TYPE_INT
,
TYPE_FLOAT
and
TYPE_DOUBLE
datatypes.

Constructs a PixelInterleavedSampleModel with the specified parameters. The number of bands will be given by the length of the bandOffsets array.
dataType | The data type for storing samples. |
---|---|
w | The width (in pixels) of the region of image data described. |
h | The height (in pixels) of the region of image data described. |
pixelStride | The pixel stride of the image data. |
scanlineStride | The line stride of the image data. |
bandOffsets | The offsets of all bands. |

h is not greater than 0 |

pixelStride and w is greater

Creates a new PixelInterleavedSampleModel with the specified width and height. The new PixelInterleavedSampleModel will have the same number of bands, storage data type, and pixel stride as this PixelInterleavedSampleModel. The band offsets may be compressed such that the minimum of all of the band offsets is zero.
w | the width of the resulting SampleModel |
---|---|
h | the height of the resulting SampleModel |

Creates a new PixelInterleavedSampleModel with a subset of the bands of this PixelInterleavedSampleModel. The new PixelInterleavedSampleModel can be used with any DataBuffer that the existing PixelInterleavedSampleModel can be used with. The new PixelInterleavedSampleModel/DataBuffer combination will represent an image with a subset of the bands of the original PixelInterleavedSampleModel/DataBuffer combination.

.
Returns a hash code value for the object. This method is
supported for the benefit of hashtables such as those provided by
java.util.Hashtable
.
The general contract of hashCode
is:
hashCode
method on each of
the two objects must produce the same integer result.
equals(java.lang.Object)
method, then calling the hashCode method on each of the
two objects must produce distinct integer results. However, the
programmer should be aware that producing distinct integer results
for unequal objects may improve the performance of hashtables.
As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)
