Examples of java.awt.image.MultiPixelPackedSampleModel.createDataBuffer()

java.awt.image.MultiPixelPackedSampleModel.createDataBuffer()
Creates a DataBuffer that corresponds to this MultiPixelPackedSampleModel. The DataBuffer object's data type and size is consistent with this MultiPixelPackedSampleModel. The DataBuffer has a single bank. @return a DataBuffer with the same data type andsize as this MultiPixelPackedSampleModel.
