JPEG标准在文件中记录了一些EXIF信息,缩略图是一幅较小的JPEG图片,存储在EXIF信息段。而Windows在第一次显示缩略图时先读当前目录中的"Thumbs.db"这个文件,其实这是一个缩略图数据库,从而来判断是否有该图片的缩略图。如果不存在"Thumbs.db"文件或者该库中不存在该图片的缩略图,那么Windows会尝试取图片中的EXIF信息,判断是否存在缩略图数据。如果图片中EXIF信息中不存在缩略图信息或信息错误,那么Windows就会用插值的方法重新生成缩略图(如果可能则保存到当前目录中的"Thumbs.db"缩略图数据库中)。 对于修改缩略图方法有用ultraEdit直接编辑文件替换EXIF信息或用exifer这样的工具,这不是本文关心的内容,本文介绍用java实现的方法。

The Microsoft® Cryptographic Application Programming Interface (CryptoAPI) provides services that enable application developers to add authentication, encoding, and encryption to their Microsoft Win32® -based applications. Application developers can use the functions in the CryptoAPI without knowing anything about the underlying implementation, in much the same way as they can use a graphics library without knowing anything about the particular graphics hardware configuration.

Welcome to UnderC version 1.2.9w This package consists of the executable (UCW), a default script file, this file, and the library files. It is important that the header files end up in a include subdirectory of the directory where UCW is found. If you unzip this file using its path information ( use folder names ) this will automatically happen. You can optionally specify the UnderC directory with the environment variable UC_HOME note that this points to the directory containing ucw.exe. If you do this, then you can copy the executable anywhere and it will still be able to find the header files.
