Note that different image format readers may produce * decoded pixels in a variety of different orders. Many readers * will produce pixels in a simple top-to-bottom, * left-to-right-order, but others may use multiple passes of * interlacing, tiling, etc. The sequence of updates may even * differ from call to call depending on network speeds, for * example. A call to this method does not guarantee that all the * specified pixels have actually been updated, only that some * activity has taken place within some subregion of the one * specified. *

The particular ImageReader implementation may * choose how often to provide updates. Each update specifies * that a given region of the image has been updated since the * last update. A region is described by its spatial bounding box * (minX, minY, width, and * height); X and Y subsampling factors * (periodX and periodY); and a set of * updated bands (bands). For example, the update: *

                 * minX = 10
                 * minY = 20
                 * width = 3
                 * height = 4
                 * periodX = 2
                 * periodY = 3
                 * bands = { 1, 3 }
                 * 
* would indicate that bands 1 and 3 of the following pixels were * updated: *
                 * (10, 20) (12, 20) (14, 20)
