简单的jpeg转成avi的类

简单的jpeg转成avi的类(1)

    这是笔者写的一个小的类，用于把一系列jpeg文件转换为avi。
    首先把源码帖出来：

//AviFormat.h

#ifndef _AVI_FORMAT_H_
#define _AVI_FORMAT_H_

#include <iostream>

using namespace std;

/* 4 bytes */
typedef int Word;
typedef unsigned int DWORD;

/* for use in AVI_avih.flags */
const DWORD AVIF_HASINDEX = 0x00000010; /* index at end of file */
const DWORD AVIF_MUSTUSEINDEX = 0x00000020;
const DWORD AVIF_ISINTERLEAVED = 0x00000100;
const DWORD AVIF_TRUSTCKTYPE = 0x00000800;
const DWORD AVIF_WASCAPTUREFILE = 0x00010000;
const DWORD AVIF_COPYRIGHTED = 0x00020000;

strUCt AVI_avih
{
 DWORD usec_per_frame;   //* frame display rate (or 0L) */
 DWORD max_bytes_per_sec; //* max. transfer rate */
 DWORD padding;    //* pad to multiples of this size; */
 /* normally 2K */
 DWORD flags;
 DWORD tot_frames;   //* # frames in file */
 DWORD init_frames;
 DWORD streams;
 DWORD buff_sz; 
 DWORD width;
 DWORD height;
 DWORD reserved[4];

 AVI_avih () {}
 AVI_avih (DWORD usec, DWORD max, DWORD pad, DWORD flags, DWORD tot, DWORD init, DWORD str, DWORD buff, DWORD w, DWORD h, DWORD* re = NULL)
  :usec_per_frame (usec), max_bytes_per_sec (max), padding (pad), tot_frames (tot)
  ,init_frames (init), streams (str), buff_sz (buff), width (w), height (h) {
  if (re != NULL)
   for (int i = 0; i < 4; ++i)
    reserved[i] = re[i];
  else
