The error diffusion technique 0N/A * requires that the input color information be delivered in a special 0N/A * order from the top row to the bottom row and then left to right within 0N/A * each row, thus it is only valid in cases where the ImageProducer has 0N/A * specified the TopDownLeftRight delivery hint. If the data is not read 0N/A * in that order, no mathematical or memory access errors should occur, 0N/A * but the dithering error will be spread through the pixels of the output 0N/A * image in an unpleasant manner. 0N/A * These definitions vector the standard macro names to the "Any" 0N/A * versions of those macros. The "DitherDeclared" keyword is also 0N/A * defined to indicate to the other include files that they are not 0N/A * defining the primary implementation. All other include files 0N/A * will check for the existance of the "DitherDeclared" keyword 0N/A * and define their implementations of the Encoding macros using 0N/A * more specific names without overriding the standard names. This 0N/A * is done so that the other files can be included here to reuse 0N/A * their implementations for the specific cases. 0N/A/* Include the specific implementations for color and grayscale displays */
