BandedSampleModel JDK 1.6)

Methods

public SampleModel createCompatibleSampleModel (int w, int h) [Overrides ComponentSampleModel] [Specified in SampleModel]

Creates a new BandedSampleModel with the specified width and height.

Creates a new BandedSampleModel with the specified
width and height. The new BandedSampleModel will have the same
number of bands, storage data type, and bank indices
as this BandedSampleModel. The band offsets will be compressed
such that the offset between bands will be w*pixelStride and
the minimum of all of the band offsets is zero.
Returns: a new BandedSampleModel with the specified width and height.
Parameters:
- w - the width of the resulting BandedSampleModel
- h - the height of the resulting BandedSampleModel
Throws:
- IllegalArgumentException - if w or h equals either Integer.MAX_VALUE or Integer.MIN_VALUE
- IllegalArgumentException - if dataType is not one of the supported data types

public DataBuffer createDataBuffer () [Overrides ComponentSampleModel] [Specified in SampleModel]

Creates a DataBuffer that corresponds to this BandedSampleModel, The DataBuffer's data type, number of banks, and size will be consistent with this BandedSampleModel.

Creates a DataBuffer that corresponds to this BandedSampleModel,
The DataBuffer's data type, number of banks, and size
will be consistent with this BandedSampleModel.
Throws:
- IllegalArgumentException - if dataType is not one of the supported types.

public SampleModel createSubsetSampleModel (int[] bands) [Overrides ComponentSampleModel] [Specified in SampleModel]

Creates a new BandedSampleModel with a subset of the bands of this BandedSampleModel.

Creates a new BandedSampleModel with a subset of the bands of this
BandedSampleModel. The new BandedSampleModel can be
used with any DataBuffer that the existing BandedSampleModel
can be used with. The new BandedSampleModel/DataBuffer
combination will represent an image with a subset of the bands
of the original BandedSampleModel/DataBuffer combination.
Throws:
- RasterFormatException - if the number of bands is greater than the number of banks in this sample model.
- IllegalArgumentException - if dataType is not one of the supported data types

public boolean equals (Object o) [Inherited From ComponentSampleModel]

publicfinal int getBandOffsets () [Inherited From ComponentSampleModel]

Returns the band offset for all bands.

publicfinal int getBankIndices () [Inherited From ComponentSampleModel]

Returns the bank indices for all bands.

public Object getDataElements (int x, int y, int w, int h, Object obj, DataBuffer data) [Inherited From SampleModel]

Returns the pixel data for the specified rectangle of pixels in a primitive array of type TransferType.

Returns the pixel data for the specified rectangle of pixels in a primitive array of type TransferType. For image data supported by the Java 2D API, this will be one of DataBuffer.TYPE_BYTE, DataBuffer.TYPE_USHORT, DataBuffer.TYPE_INT, DataBuffer.TYPE_SHORT, DataBuffer.TYPE_FLOAT, or DataBuffer.TYPE_DOUBLE. Data may be returned in a packed format, thus increasing efficiency for data transfers. Generally, obj should be passed in as null, so that the Object will be created automatically and will be of the right primitive data type.

The following code illustrates transferring data for a rectangular region of pixels from DataBuffer db1, whose storage layout is described by SampleModel sm1, to DataBuffer db2, whose storage layout is described by SampleModel sm2. The transfer will generally be more efficient than using getPixels/setPixels.

             SampleModel sm1, sm2;
             DataBuffer db1, db2;
             sm2.setDataElements(x, y, w, h, sm1.getDataElements(x, y, w,
                           h, null, db1), db2);

Using getDataElements/setDataElements to transfer between two DataBuffer/SampleModel pairs is legitimate if the SampleModels have the same number of bands, corresponding bands have the same number of bits per sample, and the TransferTypes are the same.

If obj is non-null, it should be a primitive array of type TransferType. Otherwise, a ClassCastException is thrown. An ArrayIndexOutOfBoundsException may be thrown if the coordinates are not in bounds, or if obj is non-null and is not large enough to hold the pixel data.
Returns: the data elements for the specified region of pixels.
Parameters:
- x - The minimum X coordinate of the pixel rectangle.
- y - The minimum Y coordinate of the pixel rectangle.
- w - The width of the pixel rectangle.
- h - The height of the pixel rectangle.
- obj - If non-null, a primitive array in which to return the pixel data.
- data - The DataBuffer containing the image data.
Throws:
- NullPointerException - if data is null.
- ArrayIndexOutOfBoundsException - if the coordinates are not in bounds, or if obj is too small to hold the output.

public Object getDataElements (int x, int y, Object obj, DataBuffer data) [Overrides ComponentSampleModel] [Specified in SampleModel]

Returns data for a single pixel in a primitive array of type TransferType.

Returns data for a single pixel in a primitive array of type TransferType. For a BandedSampleModel, this will be the same as the data type, and samples will be returned one per array element. Generally, obj should be passed in as null, so that the Object will be created automatically and will be of the right primitive data type.

The following code illustrates transferring data for one pixel from DataBuffer db1, whose storage layout is described by BandedSampleModel bsm1, to DataBuffer db2, whose storage layout is described by BandedSampleModel bsm2. The transfer will generally be more efficient than using getPixel/setPixel.

             BandedSampleModel bsm1, bsm2;
             DataBufferInt db1, db2;
             bsm2.setDataElements(x, y, bsm1.getDataElements(x, y, null, db1),
                            db2);
