/**
|
|
* This chunk specifies how to split an image into segments for
|
|
* scaling.
|
|
*
|
|
* There are J horizontal and K vertical segments. These segments divide
|
|
* the image into J*K regions as follows (where J=4 and K=3):
|
|
*
|
|
* F0 S0 F1 S1
|
|
* +-----+----+------+-------+
|
|
* S2| 0 | 1 | 2 | 3 |
|
|
* +-----+----+------+-------+
|
|
* | | | | |
|
|
* | | | | |
|
|
* F2| 4 | 5 | 6 | 7 |
|
|
* | | | | |
|
|
* | | | | |
|
|
* +-----+----+------+-------+
|
|
* S3| 8 | 9 | 10 | 11 |
|
|
* +-----+----+------+-------+
|
|
*
|
|
* Each horizontal and vertical segment is considered to by either
|
|
* stretchable (marked by the Sx labels) or fixed (marked by the Fy
|
|
* labels), in the horizontal or vertical axis, respectively. 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 horizontal 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] and 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. Segments that are completely transparent
|
|
* will always have the value TRANSPARENT_COLOR.
|
|
*
|
|
* The PNG chunk type is "npTc".
