Small utility for dumping Leptonica Pix data to the screen.
void dump(PIX* pix) { int_t w = pix->w; int_t h = pix->h; int_t wpl = pixGetWpl(pix); l_uint32* data = pixGetData(pix); l_uint32* line; printf("\n"); printf("Depth : %d \n", pix->d); for (int_t y = 0; y < h; ++y) { printf("%04d : ", y); line = data + y * wpl; for (int_t x = 0; x < w; ++x) { l_uint32 val = 0; if(pix->d == 1) val = GET_DATA_BIT(line, x); else if(pix->d == 2) val = GET_DATA_DIBIT(line, x); else if(pix->d == 4) val = GET_DATA_QBIT(line, x); else // 8, 16, 32 val = GET_DATA_BYTE(line, x); printf("%03d ", val); } printf("\n"); } } |
