图像缩放代码由是JPEG组的analyst编写，特点是可以对32位的图像数据进行任何比例的缩放操作，代码是经过MMX优化的在线汇编，速度相当快（大概是同功能C++代码的十倍以上，在ISee中我们用它来生成拇指图，效果很不错的）。-image scaling code from JPEG is the analyst group prepared, it is characterized by a pair of 32-bit image data scaling proportion of any operation, After MMX code is optimized online compilation, very fast (roughly the same function code C over 10 times, in ISee we use it to the thumb generation plans, the effect is quite good).
