Capturing sonograms/spectragrams as a graphic files

I am trying to make a sonogram of an entire piece.

I would like to have the sonogram with the time line below it as a
graphic file that i could then edit and use in a score (photoshop/
illustrator/gimp/whatever) and in papers, etc. & co.

Sonogram in Max/MSP is great. I use it a lot to look at real time
input and sound files, but is there anyway to capture the out put of
that with a time line below and freq along the side(for each page)? or
alternately any other software that slurps in some audio and pumps out
a hi res graphic? Years ago i was able to do such a thing in matlab...
but of course i suck at matlab, and no longer have it anyway.

cheers,

kevin
