An estimate of the area that will be updated by the pass is indicated by the minX, minY, width, and height parameters. If the pass is interlaced, that is, it only updates selected rows or columns, the periodX and periodY parameters will indicate the degree of subsampling. The set of bands that may be affected is indicated by the value of bands.
@param source the ImageReader object calling thismethod.
@param theImage the BufferedImage being updated.
@param pass the numer of the pass that is about to begin,starting with 0.
@param minPass the index of the first pass that will be decoded.
@param maxPass the index of the last pass that will be decoded.
@param minX the X coordinate of the leftmost updated columnof pixels.
@param minY the Y coordinate of the uppermost updated rowof pixels.
@param periodX the horizontal spacing between updated pixels;a value of 1 means no gaps.
@param periodY the vertical spacing between updated pixels;a value of 1 means no gaps.
@param bands an array of ints indicating the theset bands that may be updated.
