What software should I use for designing a math textbook?

I am currently writing a math textbook, and want to know what software publishers / authors use to design their book. I am currently using LaTeX to write up my book, however I need a software that can do fancy graphics as well as support math fonts. Any suggestions on software packages will be greatly appreciated.

TeXnic Center

You can generate a PDF file from simple text and LaTeX format... perfect for math rendering

For fancy graphics.....Photoshop

emacs

i was not joking. build your own handcrafted ppms in emacs.
