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". 103 */ 104 struct Res_png_9patch 105 { 106 Res_png_9patch() : wasDeserialized(false), xDivs(NULL), 107 yDivs(NULL), colors(NULL) { } 108 109 int8_t wasDeserialized; 110 int8_t numXDivs; 111 int8_t numYDivs; 112 int8_t numColors; 113 114 // These tell where the next section of a patch starts. 115 // For example, the first patch includes the pixels from 116 // 0 to xDivs[0]-1 and the second patch includes the pixels 117 // from xDivs[0] to xDivs[1]-1. 118 // Note: allocation/free of these pointers is left to the caller. 119 int32_t* xDivs; 120 int32_t* yDivs; 121 122 int32_t paddingLeft, paddingRight; 123 int32_t paddingTop, paddingBottom; 124 125 enum { 126 // The 9 patch segment is not a solid color. 127 NO_COLOR = 0x00000001, 128 129 // The 9 patch segment is completely transparent. 130 TRANSPARENT_COLOR = 0x00000000 131 }; 132 // Note: allocation/free of this pointer is left to the caller. 133 uint32_t* colors; 134 135 // Convert data from device representation to PNG file representation. 136 void deviceToFile(); 137 // Convert data from PNG file representation to device representation. 138 void fileToDevice(); 139 // Serialize/Marshall the patch data into a newly malloc-ed block 140 void* serialize(); 141 // Serialize/Marshall the patch data 142 void serialize(void* outData); 143 // Deserialize/Unmarshall the patch data 144 static Res_png_9patch* deserialize(const void* data); 145 // Compute the size of the serialized data structure 146 size_t serializedSize(); 147 }; 148 149 /** ******************************************************************** 150 * Base Types 151 * 152 * These are standard types that are shared between multiple specific 153 * resource types. 154 * 155 *********************************************************************** */ 156 157 /** 158 * Header that appears at the front of every data chunk in a resource. 159 */ 160 struct ResChunk_header 161 { 162 // Type identifier for this chunk.
