Hi everyone,
I have a program that produces postscript files on the fly
The color of the files produced are in black and white
I want to change the text color of postscript file as the file is being produced without having to manually go into the ps file and change it myself.
Any Ideas?
Thanks
If it's just a simple change of some text to another, that can be done with sed. You'd have to post an example of what you'd want changed.
I know it can be done with sed: However "what" do you change to "what"?
If you are familiar with ps file syntax please give an example.
Thanks
That depends on the current contents of the file, really.
Of course it does, hehehe 
Hi was able to put some color in the file using a2ps
You can download a2ps from macports.
a2ps -R --column=1 --no-header --font-size=20 --pretty-print=js --highlight-level=heavy --pro=color --left-title=ITITLE1 --right-title=ITITLE2 -o temp.ps file.txt

Now this produces a file with only some of the words colored.
In order to make all the words colored I edited the js stylesheet.
Actually I created my own stylesheet and called it js2
You have to use awk ans sed commands to put the words from your file into the js2 file.
Here are the steps one by one.
sudo vi /opt/local/share/a2ps/sheets/js2.ssh
Next link the file to your real js2.ssh file in your working directory
ln -s /opt/local/share/a2ps/sheets/js2.ssh ./js2.ssh
Next write a script to create js2.ssh file in your working directory here is a copy of my own called makejs2
