How to edit a PS file?
Few people want to edit HPGL or PCL. PostScript is yet another control language used by some laser printers. In most cases PostScript file is algorithmically derived from some human-readable document. Get the original document, if possible. Visual editing requires interpretation of the PS file, editing of the objects, and generation of a new PostScript file. Few applications support all features of PostScript graphic model. Unsupported features will be lost or approximated. Being a programming language PostScript can take different branches depending on the execution environment. Untaken branches will be discarded by the interpreter leaving no trace in the editor. When the printer driver generates PS file it doesn’t care about preserving high-level structure. It can be very difficult to do something beyond fixing a spelling error or changing a page number. Many mainstream graphic editors can import PS files. The quality of the built-in interpreters varies and is often limited to level
