Package net.sourceforge.jiu.color.promotion Description

Classes to convert JIU image objects to other image types that require more memory. This is a lossless operation, all information is kept. However, the new image object typically requires more memory to store the same information. A promotion operation is necessary if a certain operation cannot be performed on a smaller image type, but once the image has been promoted to a larger type, the operation becomes possible.

Example: Convolution kernel filtering cannot be applied to paletted images. They require intensity information on each pixel. Once a paletted image has been promoted to be an RGB truecolor image, filtering is possible.
