* SampleModel and then creates an

*
* Suitable ColorModels are guaranteed to exist
* for all instances of ComponentSampleModel.
* For 1- and 3- banded SampleModels, the
* ColorModel will be opaque. For 2- and 4-banded
* SampleModels, the output will use alpha transparency
* which is not premultiplied. 1- and 2-banded data will use a
* grayscale ColorSpace, and 3- and 4-banded data a sRGB
* ColorSpace. Data with 5 or more bands will use a
* ColorSpace which satisfies compatibility constraints
* but is merely a placeholder and does not perform correct color
* conversion to and from the C.I.E. XYZ and sRGB color spaces.
*
* An instance of DirectColorModel will be created for
* instances of SinglePixelPackedSampleModel with no more
* than 4 bands.
*
* An instance of IndexColorModel will be created for
* instances of MultiPixelPackedSampleModel. The colormap
* will be a grayscale ramp with 1 << numberOfBits
* entries ranging from zero to at most 255.
*
* @param source The ImageInputStream containing all the raw
* images.
* @param sampleModel The SampleModel for all the images
* in the stream.

* in the stream.
