1. An introduction
==================
PPAnim was written to complement one of my other utilities, PowerPacker
(a command and data cruncher). It is used to play normal IFF ANIM #5 files or
ANIM files crunched with PowerPacker. The decrunching is done automatically
so the user does not have to know if a file is crunched or not. The ANIM #5
format is used by most ANIM generating programs, including DPaint III and
Videoscape 2.0.
PPAnim uses 'powerpacker.library' and 'reqtools.library', so make sure
these are present in your Libs: directory. Double-click 'Install_libs' for
an automatic installation.
If you haven't got PowerPacker you are of course missing one of the main
features of this program. PowerPacker is available as shareware (up to
version 2.3b) or as a commercial program (version 4.0a). Order a copy from
UGA, P.O.Box 881, 3700 AW Zeist, The Netherlands. The commercial version
offers several enhancements like 40 to 50 times faster crunching, overlay
support, an ARexx port, and much more.
2. Usage
========
PPAnim can be used in four different ways.
- First of all via the CLI:
If you enter 'PPAnim ?' will get a usage template. You use PPAnim like
this:
PPAnim [-h] [-j#] [-l#] [-r[#]] [-i] [-o] [<file|dir>]
The program will by default load the ANIM file and play it in a loop.
If the file was crunched using PowerPacker 2.0 or higher PPAnim will first
decrunch it for you. If the file was encrypted you will be prompted for the
password.
If you enter PPAnim without options, you will be presented with a file
requester. Entering PPAnim with a directory instead of a file as an argument
will also get you a file requester, but it will be positioned in the directory
you specified.
PPAnim has several options:
-h : This option is used to force HAM mode when no CAMG chunk is
found. If you don't specify this option PPAnim will assume a
6 plane screen is extra-halfbrite. (Note that it is wrong for
an Amiga IFF ANIM file not to have a CAMG chunk, especially
when there can be doubt about what display mode to pick!)
-j# : Set a delay between frames in jiffies. A jiffie is 1/50s (PAL)
or 1/60s (NTSC).
-l# : Set number of times to loop.
-r[#]: Select repeat mode instead of loop mode (see below) and
(optionally) set number of repeats.
-i : Force screen to be interlaced.
-o : Play the animation once, no loop (same as -l1 or -r1).
The difference between loop mode and repeat mode is the following: in
loop mode PPAnim expects the last two frames of the animation to be the same
as the first two frames, this makes looping easy and above all fast (DPaint
saves animations like this). Some animations are not like this however and
if you want these to loop correctly you must select repeat mode (-r), PPAnim
will
