ComponentColorModel suitable for use with the
given SampleModel. The SampleModel
should have a data type of DataBuffer.TYPE_BYTE,
TYPE_USHORT, or TYPE_INT and between
1 and 4 bands. Depending on the number of bands of the
SampleModel, either a gray, gray+alpha, rgb, or
rgb+alpha ColorModel is returned.public java.awt.image.WritableRaster copyData(java.awt.image.WritableRaster wr)
