[DJW:] PDF is essentially Postscript but with no user defined procedures, variables or control structures, i.e. the graphics primitives from PostScript with literal arguments. Added to postscript it has various navigations features. The normal route to PDF involves interpreing PostScript and outputting the prmitives that actually produce output. (Some PDF primitives would normally be defined as functions in the prologue to a PostScript document.) I think PDF was largely intended as a simplified PostScript for the desktop machines of the time that it was developed, but there may be some reasons to do with better protection of intellectual property in the content, although I can't work out what they would be. > because the "only" thing you need to do is "learn" PDF, and embed the > HTML form results in the PDF form.

If you can afford the 1 to 3 man weeks per page to program things properly (validation etc.) you will have only one variant format, so the only bureaucratic concern would be to do with the legal validity of alternative medium (does the form filler understand the nuances that were in the original layout; has he got a signature, etc.) You can meet all the requirements by spending money on developing the web applications, spending money on indivually printing forms, and spending money on shipping those forms to the originator for signature. It's probably arguable whether you need to spend more money on supporting people filling in the electronic forms than you have to spend on people who can't understand the instructions on the printed forms. DJW:] (The easiest way of embedding into PDF would be to convert the PDF to Postscript and insert the overlay at the end of the page and then convert back to PDF, but there would be no real point - you might as well send the PostScript to a printer (or, as I say, have the base forma pre-printed)). -- --------------------------- DISCLAIMER --------------------------------- Any views expressed in this message are those of the individual sender, except where the sender specifically states them to be the views of BTS.
