Getting Started
---------------
There are two applications in the archive: RiScript and ScripTerm.
RiScript is a PostScript-previewer that can save the image as a draw
file (no, not only a sprite but real objects). ScripTerm is a terminal
that can be connected to the previewer.
Globally, there are two ways of using the software, namely interactively
and in batch mode. When double clicking a PostScript-file RiScript will
be started (when it is not running yet, of course) in batch mode, i.e.
without a terminal (ScripTerm). When starting the RiScript application
(double clicking the application icon) then RiScript will be started in
interactive mode (i.e. with separate terminal).
When RiScript is running in batch mode, double clicking a PostScript-file
will start a new job, i.e. the current page will be erased etc. When
RiScript is running in batch mode, a terminal can be attached by starting
the ScripTerm application _and_ selecting the menu item "interactive" in
the RiScript-application (in this order).
When the previewer is in interactive mode, it is also possible to enter
commands via the terminal (ScripTerm window). Double clicking on a Post-
Script-file in this mode will not start a new job but `add' the contents
to the current job (this means that the output will be merged). Pressing
^D will start a new interactive job. Selecting the "interactive" menu item
when in interactive mode will cause the previewer to run in batch mode.
This can also be achieved by quitting ScripTerm.
Known `Bugs'
------------
It grabs quite a lot of memory. This can be changed, but only statically.
This means that it can only be set at start-up with program parameters.
How to change this is explained in one of the Doc files. Remember, however,
that a real PostScript printer needs quite some memory (e.g. 6M).
Some missing features are:
- packed arrays (not _very_ important; the PostScript printer driver
of Acorn does however use this feature for unavailable fonts);
- Type 1 fonts (this can be a real nuisance when using special fonts);
- clipping (depends on the file whether important).
RiScript and ScripTerm are both implemented in C. This will limit the speed
but more importantly it is quite difficult to detect integer overflow (if
somebody knows a trick, please tell us). This might cause some problems.
