问题描述

如何读取JPEG文件并存储在CString变量中?我想从硬盘驱动器中读取JPEG文件并在CString中读取它.但是我已经尝试过使用CFile，但是二进制数据很好地存储在char数组中，但是在复制到CString时却失败了，
char数组中只有前4个字符被复制到CString变量中.
如何执行此操作?

How to read the JPEG file and store in CString variable? I want to read the JPEG file from the hard drive and to read it in CString. But i have tried with CFile but the binary data is stored very well in char array but while copying to CString it fails,
only first 4 characters in char array is being copied into the CString variable.
How to perform this??

推荐答案

这听起来像是在做些迟钝的事情.您知道您的CString将包含垃圾，而不是以任何有意义的方式包含图像吗?为此，您需要对其进行UUEncode编码，从而使其变大，但又能够将其存储为字符串.然后，您将获得JPEG的表示形式，可以将其解码并返回到CString中的JPEG字节.但是，它实际上并不是原始JPEG中的信息，更不用说以任何方式用作图像了.

This sounds like a retarded thing to do. You know that your CString will contain garbage, not the image in any meaningful way ? To do this, you''d need to UUEncode it, thus making it bigger, but making it able to be stored as a string. Then you''d have a representation of a JPEG that it''s possible to decode and turn back in to the bytes of a JPEG, inside a CString. But, it would not actually be the information in the original JPEG, let alone useful in any way as an image.
