If the color model in the source image is not the same as that
in the destination image, the pixels will be converted
in the destination. If the destination image is null
,
a BufferedImage
will be created with an appropriate
ColorModel
. An IllegalArgumentException
might be thrown if the number of arrays in the
LookupTable
does not meet the restrictions
stated in the class comment above, or if the source image
has an IndexColorModel
