| 45 | /** |
| 46 | * This chunk specifies how to split an image into segments for |
| 47 | * scaling. |
| 48 | * |
| 49 | * There are J horizontal and K vertical segments. These segments divide |
| 50 | * the image into J*K regions as follows (where J=4 and K=3): |
| 51 | * |
| 52 | * F0 S0 F1 S1 |
| 53 | * +-----+----+------+-------+ |
| 54 | * S2| 0 | 1 | 2 | 3 | |
| 55 | * +-----+----+------+-------+ |
| 56 | * | | | | | |
| 57 | * | | | | | |
| 58 | * F2| 4 | 5 | 6 | 7 | |
| 59 | * | | | | | |
| 60 | * | | | | | |
| 61 | * +-----+----+------+-------+ |
| 62 | * S3| 8 | 9 | 10 | 11 | |
| 63 | * +-----+----+------+-------+ |
| 64 | * |
| 65 | * Each horizontal and vertical segment is considered to by either |
| 66 | * stretchable (marked by the Sx labels) or fixed (marked by the Fy |
| 67 | * labels), in the horizontal or vertical axis, respectively. In the |
| 68 | * above example, the first is horizontal segment (F0) is fixed, the |
| 69 | * next is stretchable and then they continue to alternate. Note that |
| 70 | * the segment list for each axis can begin or end with a stretchable |
| 71 | * or fixed segment. |
| 72 | * |
| 73 | * The relative sizes of the stretchy segments indicates the relative |
| 74 | * amount of stretchiness of the regions bordered by the segments. For |
| 75 | * example, regions 3, 7 and 11 above will take up more horizontal space |
| 76 | * than regions 1, 5 and 9 since the horizontal segment associated with |
| 77 | * the first set of regions is larger than the other set of regions. The |
| 78 | * ratios of the amount of horizontal (or vertical) space taken by any |
| 79 | * two stretchable slices is exactly the ratio of their corresponding |
| 80 | * segment lengths. |
| 81 | * |
| 82 | * xDivs and yDivs point to arrays of horizontal and vertical pixel |
| 83 | * indices. The first pair of Divs (in either array) indicate the |
| 84 | * starting and ending points of the first stretchable segment in that |
| 85 | * axis. The next pair specifies the next stretchable segment, etc. So |
| 86 | * in the above example xDiv[0] and xDiv[1] specify the horizontal |
| 87 | * coordinates for the regions labeled 1, 5 and 9. xDiv[2] and |
| 88 | * xDiv[3] specify the coordinates for regions 3, 7 and 11. Note that |
| 89 | * the leftmost slices always start at x=0 and the rightmost slices |
| 90 | * always end at the end of the image. So, for example, the regions 0, |
| 91 | * 4 and 8 (which are fixed along the X axis) start at x value 0 and |
| 92 | * go to xDiv[0] and slices 2, 6 and 10 start at xDiv[1] and end at |
| 93 | * xDiv[2]. |
| 94 | * |
| 95 | * The array pointed to by the colors field lists contains hints for |
| 96 | * each of the regions. They are ordered according left-to-right and |
| 97 | * top-to-bottom as indicated above. For each segment that is a solid |
| 98 | * color the array entry will contain that color value; otherwise it |
| 99 | * will contain NO_COLOR. Segments that are completely transparent |
| 100 | * will always have the value TRANSPARENT_COLOR. |
| 101 | * |
| 102 | * The PNG chunk type is "npTc". |
