I put a little routine named BURN_IN on my web
page:

ftp://ftp.dfanning.com/pub/dfanning/outgoing/misc/burn_in.pr o

Use it like this to "burn in" any word (or phase) on any 2D or 3D image:

filename = Filepath(Subdir=['examples','data'], 'rose.jpg')
Read_JPEG, filename, image
modifiedImage = Burn_In(image, 'Coyote')
TV, modifiedImage, True=1

Should give you a couple of ideas.

This will also require FSC_Color from the Coyote Library to
run correctly:

Cheers,

David
