关于用c++实现对图片的放大，缩小以及循环播放的设置

Quoted from the author Igor Skochinsky In July I had the honor to speak at the Recon conference in Montreal, Canada. It was my first conference but I really liked the experience. I hope I’ll be able to attend it in future. The presentations were recorded and hopefully will appear on the Recon site soon but for now you can check out the slides . I have also uploaded some of the tools I mentioned, most notably various filesystem extractors compiled for Win32 .
