In the - * above example, the first is horizontal segment (F0) is fixed, the - * next is stretchable and then they continue to alternate. Note that - * the segment list for each axis can begin or end with a stretchable - * or fixed segment. - * - * The relative sizes of the stretchy segments indicates the relative - * amount of stretchiness of the regions bordered by the segments. For - * example, regions 3, 7 and 11 above will take up more horizontal space - * than regions 1, 5 and 9 since the horizonal segment associated with - * the first set of regions is larger than the other set of regions. The - * ratios of the amount of horizontal (or vertical) space taken by any - * two stretchable slices is exactly the ratio of their corresponding - * segment lengths. - * - * xDivs and yDivs point to arrays of horizontal and vertical pixel - * indices. The first pair of Divs (in either array) indicate the - * starting and ending points of the first stretchable segment in that - * axis. The next pair specifies the next stretchable segment, etc. So - * in the above example xDiv[0] and xDiv[1] specify the horizontal - * coordinates for the regions labeled 1, 5 and 9. xDiv[2] and - * xDiv[3] specify the coordinates for regions 3, 7 and 11. Note that - * the leftmost slices always start at x=0 and the rightmost slices - * always end at the end of the image. So, for example, the regions 0, - * 4 and 8 (which are fixed along the X axis) start at x value 0 and - * go to xDiv[0] amd slices 2, 6 and 10 start at xDiv[1] and end at - * xDiv[2]. - * - * The array pointed to by the colors field lists contains hints for - * each of the regions. They are ordered according left-to-right and - * top-to-bottom as indicated above. For each segment that is a solid - * color the array entry will contain that color value; otherwise it - * will contain NO_COLOR.
