java.awt.image
class PixelInterleavedSampleModel

java.lang.Object extended by java.awt.image.SampleModel extended by java.awt.image.ComponentSampleModel extended by java.awt.image.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.

Constructor Detail

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.
Method Detail

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
