求助！！由二进制还原成图片
图片数据，头不懂怎么加。请问哪位大神，帮且搞搞。。
数据很清楚，
图像大小 134*169
图片数据大小 5386
二进制数据在

..... 图片还原显示 二进制
[解决办法]
得根据数据格式才可以显示吧。比如BMP文件，头部有图片的各种信息的，先读取到以后才可以根据这些来处理后续的数据块部分
[解决办法]
信息不完全，图像大小为134*169，而数据大小5386却与134*169没有什么倍数关系，所以极有可能是某种压缩格式，必须弄清楚图片的颜色格式，和像素数据压缩方式才能还原图片。

取二进制数据的文件头 比较以后得出文件的后缀 然后以*.后缀的形式保存 比如 *.jpg
