I have an application that needs to be able to convert a jpeg into hex ascii, and then put that hex ascii into a postscript file. I know of one way to put this jpeg into postscript, but that's without using the jpeg's hex - instead, it uses a local path to a filename. I need to know two things:

1. Within a jpeg, how can I extract the hex ascii to use in postscript, in a way that postscript will understand it? Do I need all the header information? If anyone has done this before, please shed some insight. I have found the red book to be not as helpful for this specific problem as I would like.

2. Within said postscript file, how do I enter the hex of the jpeg back so that it will display properly?

Thank you very much.
