C # Implementing word converting PNG pictures

Because of the project needs, after some great God's guidance and github,stackoverflow to find information, wrote a program such as this.

The main reason is that Word documents have special fonts, and special font processing uses enhmetafilebits, which is to get enhanced meta information for one page of content. The type belongs to Emfplusdual.

Here, special thanks to github,stackoverflow,csdn three websites, people who are able to share technology and who are willing to help others.

Although most of the code can be found on the Internet, but there are a little bit of their own ideas, but also a little contribution to the code industry.

Code:
