| MultiBandsIndexColorModel | | final class MultiBandsIndexColorModel extends IndexColorModel (Code) | | An
IndexColorModel tolerant with image having more than one band.
Reminder:
MultiBandsIndexColorModel.getNumComponents will returns 3 or 4 no matter
how many bands were specified to the constructor. This is not specific to this class;
IndexColorModel behave that way. So we can't rely on this method for checking
the number of bands.

| Method Summary | |
| public SampleModel | createCompatibleSampleModel(int width, int height)
Creates a
SampleModel with the specified
width and height that has a data layout compatible with
this
ColorModel . | | public WritableRaster | createCompatibleWritableRaster(int width, int height)
Creates a
WritableRaster with the specified width
and height that has a data layout (
SampleModel )
compatible with this
ColorModel . | | public int | getAlpha(Object inData)
Returns the alpha component for the specified pixel, scaled from 0 to 255. | | public int | getBlue(Object inData)
Returns the blue color component for the specified pixel, scaled
from 0 to 255 in the default RGB
ColorSpace , sRGB. | | public int[] | getComponents(Object pixel, int[] components, int offset)
Returns an array of unnormalized color/alpha components for a specified pixel
in this color model. | | public Object | getDataElements(int RGB, Object pixel)
Returns a data element array representation of a pixel in this color model,
given an integer pixel representation in the default RGB color model.
This method returns an array with a length equals to the number of bands specified to
the constructor (
IndexColorModel would returns an array of length 1). | | public int | getGreen(Object inData)
Returns the green color component for the specified pixel, scaled
from 0 to 255 in the default RGB
ColorSpace , sRGB. | | public int | getRed(Object inData)
Returns the red color component for the specified pixel, scaled
from 0 to 255 in the default RGB
ColorSpace , sRGB. | | public boolean | isCompatibleRaster(Raster raster)
Returns
true if
raster is compatible
with this
ColorModel . | | public boolean | isCompatibleSampleModel(SampleModel sm)
Checks if the specified
SampleModel is compatible
with this

| getAlpha | | public int getAlpha(Object inData)(Code) | | Returns the alpha component for the specified pixel, scaled from 0 to 255.
|
| getBlue | | public int getBlue(Object inData)(Code) | | Returns the blue color component for the specified pixel, scaled
from 0 to 255 in the default RGB

| getDataElements | | public Object getDataElements(int RGB, Object pixel)(Code) | | Returns a data element array representation of a pixel in this color model,
given an integer pixel representation in the default RGB color model.
This method returns an array with a length equals to the number of bands specified to
the constructor (
IndexColorModel would returns an array of length 1). All array
elements are set to the same value. Replicating the pixel value is a somewhat arbitrary
choice, but this choice make this image appears as a gray scale image if the underlying
DataBuffer were displayed again with a RGB color model instead of this one. Such
a gray scale image seems more neutral than an image where only the Red component would vary.
All other
getDataElement methods in this color model are ultimately defined in terms
of this method, so overriding this method should be enough.
