Description: 本程序在EVC4.0+PPC SDK 2003下调试通过。
用Independent JPEG Group发行的JpegLib进行Jpeg图像的读取与保存。
这里只加了一个简单的处理示例——负片。其他的处理可以用与这个类似的方法，有了处理的算法对像素数据进行操作。或者加上鼠标事件的处理来完成绘画功能等等，这里主要是对JPEG文件进行操作的部分。
注意：程序中的CTScreenBuffer并未使用，原因是使用它加载后有段内存没有释放，加上BMP数据本来就比较好处理，所以自己写一段，将BMP数据加上头信息就可以CreateDIBSection了。
保存的默认质量Q=85，大家在使用时可以按照要求改变。
对应的PC版可以在VC下面编译使用，是基本的图象处理程序框架。

Here are adding a simple example of the treatment -- Negative. Other treatment can be used with a similar approach, with the right algorithm pixel data for the operation. Mouse or with the handling of the incident to complete the painting functions, and so on, here are the major JPEG files part of the operation. Note : CTScreenBuffer the procedures had not been used. It is due to the use of loading after not release memory, coupled with BMP data was relatively easy to deal with. So he has written section BMP data will be coupled with the first information on the CreateDIBSection. Preserve the quality of the default Q = 85, we can use the request Platform: |

<3>这里没有JPEG算法的解压程序，压缩后的数据存成标准的JPEG文件格式，任何视图软件都可以打开。DPCM方法中的解
压缩程序将数据仍然存成com格式，可以将其转成PGM格式观看，压缩包中由com转为PGM格式的程序。-Since the rate allocation algorithm is not defined by the standard, JJ2000 has implemented the so-called EBCOT algorithm.
Information about this algorithm can be found in the Verification Model (see [3]). The choice of using this algorithm makes
it possible to run extensive tests and code-streams exchange with the Verification Model software and thus ensure verification
