pr2, pr3, pr4 - Aldus/Adobe Persuation
File Juicer should extract images from Aldus Persuation files. If they are in JPG, PNG or GIF (and maybe PICT) format.
Likewise text may be extracted in rather raw format, so cleanup and removal of junk text is needed
Persuation was last released in 1996, so few of these files exist. You are welcome to send me some for testing!
