createComponentColorModel
public static java.awt.image.ColorModel createComponentColorModel(java.awt.image.SampleModel sm)
- A convenience method to create an instance of
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.
