class PixelInterleavedSampleModel
public class PixelInterleavedSampleModel
extends ComponentSampleModel
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
{@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
{@link DataBuffer#TYPE_DOUBLE TYPE_DOUBLE} datatypes.

PixelInterleavedSampleModel
public PixelInterleavedSampleModel(int dataType,
int w,
int h,
int pixelStride,
int scanlineStride,
int[] bandOffsets)
-
Constructs a PixelInterleavedSampleModel with the specified parameters.
The number of bands will be given by the length of the bandOffsets
array.
- Parameters:
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.
createCompatibleSampleModel
public SampleModel createCompatibleSampleModel(int w,
int h)
-
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.
- Overrides:
createCompatibleSampleModel
in class ComponentSampleModel
- Parameters:
w
- the width of the resulting SampleModel
h
- the height of the resulting SampleModel
- Returns:
- a new
SampleModel
with the specified width
and height.
createSubsetSampleModel
public SampleModel createSubsetSampleModel(int[] bands)
-
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.
- Overrides:
createSubsetSampleModel
in class ComponentSampleModel
- Parameters:
bands
hashCode
public int hashCode()
-
- Overrides:
hashCode
in class ComponentSampleModel
