Examples of javax.imageio.event.IIOReadUpdateListener.thumbnailPassStarted()

javax.imageio.event.IIOReadUpdateListener.thumbnailPassStarted()

Reports that the current thumbnail read operation is about to begin a progressive pass. Readers of formats that support progressive encoding should use this to notify clients when each pass is completed when reading a progressively encoded thumbnail image. @param source the ImageReader object calling thismethod. @param theThumbnail the BufferedImage thumbnailbeing updated. @param pass the number 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. @see #passStarted
