In the 80 | * above example, the first is horizontal segment (F0) is fixed, the 81 | * next is stretchable and then they continue to alternate. Note that 82 | * the segment list for each axis can begin or end with a stretchable 83 | * or fixed segment. 84 | * 85 | * The relative sizes of the stretchy segments indicates the relative 86 | * amount of stretchiness of the regions bordered by the segments. For 87 | * example, regions 3, 7 and 11 above will take up more horizontal space 88 | * than regions 1, 5 and 9 since the horizontal segment associated with 89 | * the first set of regions is larger than the other set of regions. The 90 | * ratios of the amount of horizontal (or vertical) space taken by any 91 | * two stretchable slices is exactly the ratio of their corresponding 92 | * segment lengths. 93 | * 94 | * xDivs and yDivs are arrays of horizontal and vertical pixel 95 | * indices. The first pair of Divs (in either array) indicate the 96 | * starting and ending points of the first stretchable segment in that 97 | * axis. The next pair specifies the next stretchable segment, etc. So 98 | * in the above example xDiv[0] and xDiv[1] specify the horizontal 99 | * coordinates for the regions labeled 1, 5 and 9. xDiv[2] and 100 | * xDiv[3] specify the coordinates for regions 3, 7 and 11. Note that 101 | * the leftmost slices always start at x=0 and the rightmost slices 102 | * always end at the end of the image. So, for example, the regions 0, 103 | * 4 and 8 (which are fixed along the X axis) start at x value 0 and 104 | * go to xDiv[0] and slices 2, 6 and 10 start at xDiv[1] and end at 105 | * xDiv[2]. 106 | * 107 | * The colors array contains hints for each of the regions. They are 108 | * ordered according left-to-right and top-to-bottom as indicated above. 109 | * For each segment that is a solid color the array entry will contain 110 | * that color value; otherwise it will contain NO_COLOR.

In the 80 | * above example, the first is horizontal segment (F0) is fixed, the 81 | * next is stretchable and then they continue to alternate. Note that 82 | * the segment list for each axis can begin or end with a stretchable 83 | * or fixed segment. 84 | * 85 | * The relative sizes of the stretchy segments indicates the relative 86 | * amount of stretchiness of the regions bordered by the segments. For 87 | * example, regions 3, 7 and 11 above will take up more horizontal space 88 | * than regions 1, 5 and 9 since the horizontal segment associated with 89 | * the first set of regions is larger than the other set of regions. The 90 | * ratios of the amount of horizontal (or vertical) space taken by any 91 | * two stretchable slices is exactly the ratio of their corresponding 92 | * segment lengths. 93 | * 94 | * xDivs and yDivs are arrays of horizontal and vertical pixel 95 | * indices. The first pair of Divs (in either array) indicate the 96 | * starting and ending points of the first stretchable segment in that 97 | * axis. The next pair specifies the next stretchable segment, etc. So 98 | * in the above example xDiv[0] and xDiv[1] specify the horizontal 99 | * coordinates for the regions labeled 1, 5 and 9. xDiv[2] and 100 | * xDiv[3] specify the coordinates for regions 3, 7 and 11. Note that 101 | * the leftmost slices always start at x=0 and the rightmost slices 102 | * always end at the end of the image. So, for example, the regions 0, 103 | * 4 and 8 (which are fixed along the X axis) start at x value 0 and 104 | * go to xDiv[0] and slices 2, 6 and 10 start at xDiv[1] and end at 105 | * xDiv[2]. 106 | * 107 | * The colors array contains hints for each of the regions. They are 108 | * ordered according left-to-right and top-to-bottom as indicated above. 109 | * For each segment that is a solid color the array entry will contain 110 | * that color value; otherwise it will contain NO_COLOR.
