Class ComponentSampleModel

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

getNumDataElements

public final int getNumDataElements()
Returns the number of data elements needed to transfer a pixel with the getDataElements(int, int, Object, DataBuffer) and setDataElements(int, int, Object, DataBuffer) methods. For a ComponentSampleModel, this is identical to the number of bands.

Specified by:
getNumDataElements in class SampleModel
Returns:
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 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.

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 ouput.

                            DataBuffer data)

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.

setSample

public void setSample(int x,
                      int y,
                      int b,
                      double s,
                      DataBuffer data)
Sets a sample in the specified band for the pixel located at (x,y) in the DataBuffer using a double for input. An ArrayIndexOutOfBoundsException might be thrown if the coordinates are not in bounds.

Overrides:
setSample in class SampleModel
Parameters:
x - The X coordinate of the pixel location
y - The Y coordinate of the pixel location
b - The band to set
s - The input sample as a double
data - The DataBuffer containing the image data

getSample(int, int, int, DataBuffer)

setSamples

public void setSamples(int x,
                       int y,
                       int w,
                       int h,
                       int b,
                       int[] iArray,
                       DataBuffer data)
Sets the samples in the specified band for the specified rectangle of pixels from an int array containing one sample per data array element. An ArrayIndexOutOfBoundsException might be thrown if the coordinates are not in bounds.

Overrides:
setSamples in class SampleModel
Parameters:
x - The X coordinate of the upper left pixel location
y - The Y coordinate of the upper left pixel location
w - The width of the pixel rectangle
h - The height of the pixel rectangle
b - The band to set
iArray - The input samples in an int array
data - The DataBuffer containing the image data

equals

public boolean equals(Object o)
Description copied from class: Object
Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

Overrides:
equals in class Object
Parameters:
o - the reference object with which to compare.
Returns:
true if this object is the same as the obj argument; false otherwise.
See Also:
Object.hashCode(), Hashtable

hashCode

public int hashCode()
Description copied from class: Object
Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided by java.util.Hashtable.

The general contract of hashCode is:

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)

Overrides:
hashCode in class Object
Returns:
a hash code value for this object.

Object.equals(java.lang.Object), Hashtable
