| 60 | /** |
| 61 | * This chunk specifies how to split an image into segments for |
| 62 | * scaling. |
| 63 | * |
| 64 | * There are J horizontal and K vertical segments. These segments divide |
| 65 | * the image into J*K regions as follows (where J=4 and K=3): |
| 66 | * |
| 67 | * F0 S0 F1 S1 |
| 68 | * +-----+----+------+-------+ |
| 69 | * S2| 0 | 1 | 2 | 3 | |
| 70 | * +-----+----+------+-------+ |
| 71 | * | | | | | |
| 72 | * | | | | | |
| 73 | * F2| 4 | 5 | 6 | 7 | |
| 74 | * | | | | | |
| 75 | * | | | | | |
| 76 | * +-----+----+------+-------+ |
| 77 | * S3| 8 | 9 | 10 | 11 | |
| 78 | * +-----+----+------+-------+ |
| 79 | * |
| 80 | * Each horizontal and vertical segment is considered to by either |
| 81 | * stretchable (marked by the Sx labels) or fixed (marked by the Fy |
| 82 | * labels), in the horizontal or vertical axis, respectively. In the |
| 83 | * above example, the first is horizontal segment (F0) is fixed, the |
| 84 | * next is stretchable and then they continue to alternate. Note that |
| 85 | * the segment list for each axis can begin or end with a stretchable |
| 86 | * or fixed segment. |
| 87 | * |
| 88 | * The relative sizes of the stretchy segments indicates the relative |
| 89 | * amount of stretchiness of the regions bordered by the segments. For |
| 90 | * example, regions 3, 7 and 11 above will take up more horizontal space |
Mathias Agopian | 5f91097 | 2009-06-22 02:35:32 -0700 | [diff] [blame] | 91 | * than regions 1, 5 and 9 since the horizontal segment associated with |
The Android Open Source Project | 9066cfe | 2009-03-03 19:31:44 -0800 | [diff] [blame] | 92 | * the first set of regions is larger than the other set of regions. The |
| 93 | * ratios of the amount of horizontal (or vertical) space taken by any |
| 94 | * two stretchable slices is exactly the ratio of their corresponding |
| 95 | * segment lengths. |
| 96 | * |
Narayan Kamath | 6381dd4 | 2014-03-03 17:12:03 +0000 | [diff] [blame] | 97 | * xDivs and yDivs are arrays of horizontal and vertical pixel |
The Android Open Source Project | 9066cfe | 2009-03-03 19:31:44 -0800 | [diff] [blame] | 98 | * indices. The first pair of Divs (in either array) indicate the |
| 99 | * starting and ending points of the first stretchable segment in that |
| 100 | * axis. The next pair specifies the next stretchable segment, etc. So |
| 101 | * in the above example xDiv[0] and xDiv[1] specify the horizontal |
| 102 | * coordinates for the regions labeled 1, 5 and 9. xDiv[2] and |
| 103 | * xDiv[3] specify the coordinates for regions 3, 7 and 11. Note that |
| 104 | * the leftmost slices always start at x=0 and the rightmost slices |
| 105 | * always end at the end of the image. So, for example, the regions 0, |
| 106 | * 4 and 8 (which are fixed along the X axis) start at x value 0 and |
Mathias Agopian | 5f91097 | 2009-06-22 02:35:32 -0700 | [diff] [blame] | 107 | * go to xDiv[0] and slices 2, 6 and 10 start at xDiv[1] and end at |
The Android Open Source Project | 9066cfe | 2009-03-03 19:31:44 -0800 | [diff] [blame] | 108 | * xDiv[2]. |
| 109 | * |
Narayan Kamath | 6381dd4 | 2014-03-03 17:12:03 +0000 | [diff] [blame] | 110 | * The colors array contains hints for each of the regions. They are |
| 111 | * ordered according left-to-right and top-to-bottom as indicated above. |
| 112 | * For each segment that is a solid color the array entry will contain |
| 113 | * that color value; otherwise it will contain NO_COLOR. Segments that |
| 114 | * are completely transparent will always have the value TRANSPARENT_COLOR. |
