Possible to read in postscript file?

I am thinking about converting an application I wrote from tcl/tk to Squeak. The app must allow the user to enter and edit formatted text -- a TextMorph works fine for this. In the tcl/tk version I save each entry to an individual file, marked up with formatting commands I created. The tk text widget handles formatted text, it just doesn't include methods for dumping and restoring the format tags. A Squeak TextMorph can save itself to a postscript file. Can it read one of these files and recreate the marked-up text?

On a bigger picture, not sure if I should follow this model or just save everything in the image. Disk space is disk space either way. If the tool is set up in its own project space it is relatively easy to file out, right? And back, say for back-up purposes? Thoughts?
