hzk16竖排 转换c程序

自己写的垃圾程序,仅仅表现为能用,错误处理和代码优化暂时都抛弃了.如果用python,应当快多了.先贴出c的,里面的gcc4_debug.h里面只用到ERRX()
可以自己在程序开头定义一个.

编译: gcc 即可.

#include "/dvr/debug/gcc4_debug.h"
#include <stdio.h>
#include <stdlib.h>
#include <fcntl.h>

int itoa(int a, char *s, int n)
{ int i;

    for(i = 0; i < n; i++, s++)
    {
        if((a & (1 << i)) != 0)
            *s = '1';
        else
            *s = '0';
    }
    return 0;
}

int convert(unsigned char *buf, int size)
{
    unsigned char ss[16][2][8];
    unsigned char st[4][8][8];
    int i,j,k;
    int m;
    

    if(size%2 != 0)
    {
        printf("size is %d\n", size);
        ERRX(size is not a even
    }

    for(i = 0; i < 16; i++)
        for(j = 0; j < 2; j++)
            for(k = 0; k < 8; k++)
            {
                if((*(buf+ i*2 + j) & ( 1 << k)) != 0)
                    ss[i][j][7 - k] = 1;
                else
                    ss[i][j][7 - k] = 0;
        
            }
   
    for(i = 0; i < 8; i ++)
        for(j = 0; j < 8; j++)
        {
            st[0][i][j] = ss[j][0][i];
            st[1][i][j] = ss[j][1][i];
            st[2][i][j] = ss[8+j][0][i];
            st[3][i][j] = ss[8+j][1][i];
        }

    
    for(i = 0; i < 4; i++)
        for(j = 0; j < 8; j++)
        {
            m = 0;
            for(k = 0; k < 8; k++)
                if(st[i][j][k] != 0)
                   m |= st[i][j][k] << k;
            *(buf++) = m;
    
        }
   


}

    int bytes;
    int i;


    if((fp1 = fopen("./HZK16", "rb")) == NULL)
