用QT实现事件处理，定时器事件允许应用程序可以在一定的时间|司隔后执行事件处理，这个窗口部件显示 了一串文本标语，它会每30毫秒向左移动一个像素。如果窗口部件比文本宽，那么文本将会被多次重复， 直到能够填满整个窗口部件的宽度为止。定时器事件是‘种低级事件，而且如果需要多个定时器时，保持 对所有定时器囚的跟踪将会变得很麻烦。在这种情况下，通常更为简单的方式是为每一个定时器分别创 建一个们中er对象。QTimer会在每个时间间隔发射timeout()信号。

This a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious. -This is a JPEG encoding & decoding program of still image. It does not use level shifting.
