实现一个图像缩放算法，不调用对算法本身有帮助的库函数，将图像缩放到指定的大小。

具体功能：

1.输入为用windows画图程序生成的无压缩BMP图片，只支持256色位图和24位色位图，输出格式与输入格式相同，要求也要能用Windows画图程序打开；

2.支持批量转换，一次转换的张数不作限制，命令行接口指令如下：

Zoom.Exe imagelist.txt

其中imagelist.txt的保持待转换的文件列表，以纯文本格式指定了每幅图片转换后的宽度和高度，格式示例如下：

Image1.bmp 320,240

Image2.bmp 320,240

程序使用说明：

1、将Mindray.exe、imagelist.txt和用于缩放的位图文件放在相同目录下；

2、在运行窗口中输入“cmd”进入cmd.exe

3、输入Mindray.exe所在路径，例如“e:”

4、输入指定格式命令行：Mindray.exe 1.txt执行程序，得到处理结果。

-To achieve an image scaling algorithm, the algorithm itself does not help call the library functions to scale the image to the specified size.

Specific functions:

1 input for the use of windows drawing program to generate uncompressed BMP images, which only supports 256 colors and 24-bit color bitmap bitmap output format with the same input format, requiring also can use Windows Paint program to open　

2 supports batch conversion, a conversion of the number of sheets without limit, the command line interface command is as follows:

Zoom.Exe imagelist.txt

One imagelist.txt to maintain a list of files to be converted to plain text format conversion is specified after each image width and height, format example:

Image1.bmp 320,240

Image2.bmp 320,240

Program instructions:

1, Mindray.exe, imagelist.txt and for the scaling of bitmap file in the same directory　

2 In the Run window type "cmd" to enter cmd.exe　

3, input Mindray.exe the path, such as "e:"

4, enter the speci
