PixelInterleavedSampleModel JDK 1.6)

Methods

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.
Returns: a new SampleModel with the specified width and height.
Parameters:
- w - the width of the resulting SampleModel
- h - the height of the resulting SampleModel
Throws:
- IllegalArgumentException - if w or h is not greater than 0

ComponentSampleModel.

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) [Inherited From 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 ComponentSampleModel, this is the same as the data type, and samples are returned one per array element. Generally, obj should be passed in as null, so that the Object is created automatically and is the right primitive data type.

The following code illustrates transferring data for one pixel from DataBuffer db1, whose storage layout is described by ComponentSampleModel csm1, to DataBuffer db2, whose storage layout is described by ComponentSampleModel csm2. The transfer is usually more efficient than using getPixel and setPixel.

             ComponentSampleModel csm1, csm2;
             DataBufferInt db1, db2;
             csm2.setDataElements(x, y,
                            csm1.getDataElements(x, y, null, db1), db2);

Using getDataElements and setDataElements to transfer between two DataBuffer/SampleModel pairs is legitimate if the SampleModel objects 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 not null, it should be a primitive array of type TransferType. Otherwise, a ClassCastException is thrown. An ArrayIndexOutOfBoundsException might be thrown if the coordinates are not in bounds, or if obj is not null and is not large enough to hold the pixel data.
Returns: the data of the specified pixel
Parameters:
- x - the X coordinate of the pixel location
- y - the Y coordinate of the pixel location
- obj - if non-null, a primitive array in which to return the pixel data
