287 | * normalization is done as required to present the data in this order. | |

289 | * The ZNORMALIZE macro performs byte and nibble order normalization if | |
290 | * required for Z format data. | |
291 | * | |
292 | * The XYINDEX macro computes the index to the starting byte (char) boundary | |
293 | * for a bitmap_unit containing a pixel with coordinates x and y for image | |
294 | * data in XY format. | |
295 | * | |
296 | * The ZINDEX* macros compute the index to the starting byte (char) boundary | |
297 | * for a pixel with coordinates x and y for image data in ZPixmap format. | |
