# Class ComponentSampleModel

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

Direct Known Subclasses:
  `BandedSampleModel`, `PixelInterleavedSampleModel`

public class ComponentSampleModel extends SampleModel
This class represents image data which is stored such that each sample of a pixel occupies one data element of the DataBuffer. It stores the N samples which make up a pixel in N separate data array elements. Different bands may be in different banks of the DataBuffer. Accessor methods are provided so that image data can be manipulated directly. This class can support different kinds of interleaving, e.g. band interleaving, scanline interleaving, and pixel interleaving. 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. This class can represent image data for which each sample is an unsigned integral number which can be stored in 8, 16, or 32 bits (using `DataBuffer.TYPE_BYTE`, `DataBuffer.TYPE_USHORT`, or `DataBuffer.TYPE_INT`, respectively), data for which each sample is a signed integral number which can be stored in 16 bits (using `DataBuffer.TYPE_SHORT`), or data for which each sample is a signed float or double quantity (using `DataBuffer.TYPE_FLOAT` or `DataBuffer.TYPE_DOUBLE`, respectively). All samples of a given ComponentSampleModel are stored with the same precision. All strides and offsets must be non-negative. This class supports `TYPE_BYTE`, `TYPE_USHORT`, `TYPE_SHORT`, `TYPE_INT`, `TYPE_FLOAT`, `TYPE_DOUBLE`,

  the number of data elements needed to transfer a pixel with the `getDataElements` and `setDataElements` methods.
See Also:
  - `SampleModel.getNumDataElements()`
  - `SampleModel.getNumBands()`

### getDataElements

public Object getDataElements(int x, int y, Object obj, DataBuffer data)
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 `TransferType`s 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.

Specified by:
  `getDataElements` in class `SampleModel`
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
  `data` - the `DataBuffer` containing the image data
Returns:
  the data of the specified pixel
Throws:
  `NullPointerException` - if data is null.
  `ArrayIndexOutOfBoundsException` - if the coordinates are not in bounds, or if obj is too small to hold the output.
See Also:
  - `setDataElements(int, int, Object, DataBuffer)`

### getPixel

           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 `TransferType`s are the same.
