- Here's my opinion.
-
- The best way to do images in WWW is by using MIME. I'm sure postscript
- is already a supported subtype in MIME, and it deals very nicely with
- mixing text and graphics.
-
- But it isn't clickable, you say? Yes your right. I suspect there is
- already an answer to this in display postscript. Even if there isn't
- the addition to standard postscript is trivial. Define an anchor
- command which specifies the URL and uses the current path as a closed
- region for the button. Since postscript deals so well with paths, this
- makes arbitrary button shapes trivial.
-
- Let's call this specially modified postscript HTPS. Until HTPS becomes
- some sort of standard, every copy of HTPS should include a piece of code
- that asks the interpreter if it knows about the anchor command, and if
- it doesn't it will substitute in a null command.
-
- As far as implementation, this is easy, though not necessarily trivial.
- Ghostscript already provides the ability to bind arbitrary functions to
- mouse events. It shouldn't be too horrible to set up anchor to keep
- a table of button paths, and have mouse clicks call a function that looks
- up what button they are in.
-
- Let me point out that it wouldn't be hard to make such a system deal
- with html too. Many people already have code that converts html to
- postscript.
