Even though the man page calls for a uint ** to be passed as the second
argument, the data is probably stored in uchar format. Change your program to
look like this and it should work ok:

     unsigned char *imgptr;

    pfLoadTexFile(tex, "road.pfi");
    pfGetTexImage(tex, &image, &comp, &sx, &sy, &sz);

    imgptr = (unsigned char *)image;

    printf("comp=%d, sx=%d, sy=%d, sz=%d\n", comp, sx, sy, sz);
    for(j = 0; j < sx*sy; j++)
    {
        printf("%d\n",imgptr[j]);
    }
