Generate an image from MS-Word file in Java

I need to generate image from the word file (.docx - 2007 upward versions) using any opensource Java library.

I've Java EE application where currently I am getting the word file converted to PDF using docx4j library, but now as a requirement I need to get the header and footer part of my word template as an Image file (.jpg/.jpeg/.png).

I googled for the solution but wasn't able to find.

Any hint or solution would be appreciated.
