排查后感觉是读取数据的问题

void getData1(FILE* fp, Point** Pix, long height, long width, int offset)

{

    FILE* fpr;
    errno_t err_pr;
    FILE* fpg;
    errno_t err_pg;
    FILE* fpb;
    errno_t err_pb;


    int i, j = 0;

    int stride;

    unsigned char* pix = NULL;

    fseek(fp, offset, SEEK_SET);    //找到位图的数据区



    stride = (24 * width + 31) / 8; //对齐,计算一行有多少个8位

    stride = stride / 4 * 4;      //取四的倍数 r,g,b,alph



    //写入数组

    pix = (unsigned char*)malloc(stride);

    for (j = 0; j < height; j++)

    {

        fread(pix, 1, stride, fp);

        for (i = 0; i < width; i++)

        {

            Pix[height - j - 1][i].r = pix[i * 3 + 2];

            Pix[height - j - 1][i].g = pix[i * 3 + 1];

            Pix[height - j - 1][i].b = pix[i * 3];

        }

    }

    err_pr = fopen_s(&fpr, "bmpr1.txt", "w+");

    err_pg = fopen_s(&fpg, "bmpg1.txt", "w+");

    err_pb = fopen_s(&fpb, "bmpb1.txt", "w+");



    for (i = 0; i < height; i++)

    {

        for (j = 0; j < width; j++)

        {

            fprintf(fpr, "%4d", Pix[i][j].r);
            fprintf(fpg, "%4d", Pix[i][j].g);
            fprintf(fpb, "%4d", Pix[i][j].b);

        }

        //fprintf(fpr, "\n");

        //fprintf(fpg, "\n");

        //fprintf(fpb, "\n");

    }

这是main函数中的 调用

int main() {
    int i, j;
    ST_BITMAP* st_tp_bitmap = NULL;
    U4 offset1;
    U4 width1;
    U4 height1;

    FILE* fps;
    errno_t err;
    err = fopen_s(&fps, "adc_p0.bmp", "rb");//读取同目录下的image.bmp文件。
    if (err)
    {
        printf("打开'image.bmp'失败！\n");
        return -1;
