因为GIF89格式的图片文件只支持256色动画, 所以特地开发了一款32位色的动画文件格式, 把这种格式命名为PIZ格式,属于多帧动画, 基于帧间差值和zip压缩的算法,类似PNG的 alpha通道,640x480尺寸,700帧,要11M字节 压缩包里面包含PIZ制作器和PIZ播放器, 以及全部代码 适合linux使用 -GIF89 because the image file format only supports 256 colors animation, I ve developed a 32-color animation file formats, this format is named Piz format, are multi-frame animation, based on the interframe difference and zip compression algorithm , similar to PNG s alpha channel, 640x480 size, 700 to 11M-byte packet containing compressed production Piz and Piz player, as well as all the code for linux use

linux线程编程-linux multi-thread programming

多线程程序作为一种多任务、并发的工作方式，有以下的优点： 　　1) 提高应用程序响应。这对图形界面的程序尤其有意义，当一个操作耗时很长时，整个系统都会等待这个操作，此时程序不会响应键盘、鼠标、菜单的操作，而使用多线程技术，将耗时长的操作（time consuming）置于一个新的线程，可以避免这种尴尬的情况。 　　2) 使多CPU系统更加有效。操作系统会保证当线程数不大于CPU数目时，不同的线程运行于不同的CPU上。 　　3) 改善程序结构。一个既长又复杂的进程可以考虑分为多个线程，成为几个独立或半独立的运行部分，这样的程序会利于理解和修改。 -multithreaded process as a multi-task, complicated by the way, has the following advantages : 1) improve application response. This graphical interface is especially meaningful, when a very long time-consuming operation, the entire system will wait for the operation, this procedure will not respond to keyboard, mouse, the menu of operations, and the use of multithreading technology, long will be time-consuming operation (time consuming) under a new thread, avoided this embarrassing situation. 2) multi-CPU system more effective. When the operating system would ensure that not more than a few threads CPU number of different threads running on different CPUs. 3) to improve program structure. A long and complex
