我已经给了宏PATTERN_BITMAP的定义,请仔细审题

非常抱歉,我没有仔细审题,造成了误导。根据题目要求,将指定的位图逆时针旋转90度,并将多余的列按顺序拼接到列的后面,可以使用如下宏:
```
#define PATTERN_BITMAP_ROTATE90(pattern_array, row_size, height) \

for (int j = i; j < height - i - 1; j++) { \
uint8_t temp = PATTERN_BITMAP(pattern_array, 32, i, j); \
*((uint8_t *)pattern_array + 32 * i + j/8) &= ~(1 << (7-(j%8))); \
*((uint8_t *)pattern_array + 32 * i + j/8) |= (PATTERN_BITMAP(pattern_array, 32, j, row_size - i - 1) << (7-(j%8))); \
*((uint8_t *)pattern_array + 32 * j + (row_size - i - 1)/8) &= ~(1 << (7-((row_size - i - 1)%8))); \
