main.cpp

一个自己编的解码jpeg格式图片的VC++程序的源代码。

//Main.cpp
#include <iostream>
#include "jenc.h"

using namespace std;

int main(int argc, char* argv[])
{
 if (argc <= 1)
 {
  cout << "please input bmp filename." << endl;
  return 0;
 }

// string fileName = string("E:\\Work\\VC\\Temp\\jpeg\\jpeg_mine\\Debug\\duanwu.bmp");
 string fileName = string(argv[1]);
 string outFile = fileName.substr(0,fileName.find_last_of('.'));
 outFile = outFile + ".jpg";

 JEnc enc;
 enc.Invoke(fileName, outFile,90);
 cout << "Out:" << outFile << endl;
 cout <<"finish"<<endl;
// getchar();

	return 0;
}
