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.
emacs, you have to be joking right.
Can I use LaTex and Photoshop together ?

For example, after creating a pdf file using LaTex can I import it into photoshop ?
