本代码采用Qt开发工具进行编程，主要展示了如何可以像处理文档文件一样的去对图像文件进行编辑。该样板代码其中的格式转换对我颇有益处，另外其中还有很多处理方法，如“打开，另存，复制，另存为”等等。-The code used to program development tools, Qt, the main display can deal with how the same document to an image file to edit it. The model code of the format conversion is quite good for me, of which there are many other treatment methods, such as " open, save, copy, save as"　and so on.
