A system, method, and program storage device implementing the method for modifying images has the ability to assign color intensity values to pixels exposed during image manipulation operations. This abstract is not to be considered limiting. Therefore, the washing machine can improve the efficiency of the use of a liquid detergent. One or two optical sensor heads would be used in conjunction with a signal processor to determine the exact position of the code plate, and, in turn, the linear or rotary actuator. A portion of the plotted data is then compared to an ideal plot defined for that sub-assembly device. The domain message model may include a content definition model and an item type model for building data and object types and specifying data context and relationships.
