The version of a CGM file is encoded in its header: the METAFILE VERSION command contains the version number (1, 2, 3, 4).
CGM文件的版本在其标头中编码：METAFILE VERSION命令包含版本号（1,2,3,4）。
The jcgm library provides access to all commands of a CGM file: the CGM class has a showCGMCommands method that can be used to print them.
jcgm库提供对CGM文件的所有命令的访问：CGM类有一个showCGMCommands方法，可用于打印它们。
For the images that don't print, you can check whether the commands they're using is supported by the library since jcgm does not support all commands: jcgm implemented commands.
对于不打印的图像，您可以检查库是否支持它们正在使用的命令，因为jcgm不支持所有命令：jcgm实现的命令。
