Conversion postscript to ASCII file

[sayedmesa]

Dear All,
Do you know free program to convert Postscript to ASCII? I need it because when I plot the transmission spectrum, I can save it only as png, eps or ps file in VNL 2008.1. After I close the log file I cannot retrieve the XY data again. 

Regards,
Morad

I think what actually need is to extract the transmission "x,y" data from the VNL file, am I right? See http://quantumwise.com/forum/index.php?topic=3.0

(Converting the PS to Ascii wouldn't help one bit anyway, since the actual data points are not in the PS file, it's a picture of the graph )
