Postscript provide many encryption/decryption methods  , but also it has its own way of raster image !!

And mos applications save the images encrypted and to view it - it must be decrypted.

Easy Suggestion

Why don't you convert that postscript image (encrypted) to PDF !!  and hen Save it as *.JPG or *.BMP  as you like !!
