| java.awt.image.PixelInterleavedSampleModel
| PixelInterleavedSampleModel | | public class PixelInterleavedSampleModel extends ComponentSampleModel (Code) | | 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
DataBuffer.TYPE_BYTE TYPE_BYTE ,
DataBuffer.TYPE_USHORT TYPE_USHORT ,
DataBuffer.TYPE_SHORT TYPE_SHORT ,
DataBuffer.TYPE_INT TYPE_INT ,
DataBuffer.TYPE_FLOAT TYPE_FLOAT and
DataBuffer.TYPE_DOUBLE TYPE_DOUBLE datatypes.

| Constructor Summary | |
| public | PixelInterleavedSampleModel(int dataType, int w, int h, int pixelStride, int scanlineStride, int bandOffsets)
Constructs a PixelInterleavedSampleModel with the specified parameters. |
| Method Summary | |
| public SampleModel | createCompatibleSampleModel(int w, int h)
Creates a new PixelInterleavedSampleModel with the specified
width and height. | | public SampleModel | createSubsetSampleModel(int bands)
Creates a new PixelInterleavedSampleModel with a subset of the
bands of this PixelInterleavedSampleModel. | | public int | hashCode()
|
| PixelInterleavedSampleModel | | public PixelInterleavedSampleModel(int dataType, int w, int h, int pixelStride, int scanlineStride, int bandOffsets)(Code) | | 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.
Parameters:
w - The width (in pixels) of the region ofimage data described.
Parameters:
h - The height (in pixels) of the region ofimage data described.
Parameters:
pixelStride - The pixel stride of the image data.
Parameters:
scanlineStride - The line stride of the image data.
Parameters:
bandOffsets - The offsets of all bands.
throws:
IllegalArgumentException - if w orh is not greater than 0
throws:
IllegalArgumentException - if any offset between bands isgreater than the scanline stride
throws:
IllegalArgumentException - if the product of pixelStride and w is greaterthan scanlineStride
throws:
IllegalArgumentException - if pixelStride is less than any offset between bands
throws:
IllegalArgumentException - if dataType is notone of the supported data types |
| createCompatibleSampleModel | | public SampleModel createCompatibleSampleModel(int w, int h)(Code) | | 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.
Parameters:
w - the width of the resulting SampleModel
Parameters:
h - the height of the resulting SampleModel a new SampleModel with the specified widthand height.
throws:
IllegalArgumentException - if w orh is not greater than 0 |
| createSubsetSampleModel | | public SampleModel createSubsetSampleModel(int bands)(Code) | | 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.
