AmiFlick v2.02
An FLI player for the Amiga
©1993 Garrick Meeker
This program is hereby placed in the public domain. You may freely
distribute it as long no more than a nominal fee for time and copying costs
is charged. This document must be included with the program. I assume
no reponsibilities for the behavior of this program.
Thanks to Chris Green and Richard Addison for the chunky to planar
routine.
Have you ever wanted to use your Amiga to handle all those zillions
of FLI files for PeeCee's? Well, now there's AmiFlick. It can play FLI's
or write them to disk as a bunch of IFF's. It can also handle the newer
format of FLI's (sometimes called FLC's).
AmiFlick requires at least AmigaDOS 1.2 (I will probably, but not
definately continue to support 1.2). AmiFlick also requires
iffparse.library to write files. This is part of WB2.0, but will run under
1.2. However, the only legal way to get it is to buy WB2.0 or a program
that has licensed it (Deluxe Music is one that I know of). A lot of you
1.2 and 1.3 users won't be able to write files, and this isn't going to
change. You should probably consider upgrading, anyway. Enough said.
A version optimized for the 68030 is included, but the difference
isn't all that noticable.
Usage: AmiFlick [-v] [-d<delay>] [-f] [-c] [-h] [-g] [-s] [-l] [-b]
[-m<mode>] [-a5] [-a7s] [-a7l] [-n] file [outfile]
-v Verbose file information
-d<delay> Delay between frames in 1/70s of a second
-f Fast mode (requires more memory)
-c Color mode (requires AGA)
-h HAM mode
-g 256 shade grey mode (requires AGA)
-s Scan file only
-l Load file into memory before playing
-b Double buffer playback
-m<mode> Screen mode to use
-a5 'outfile' will be ANIM5 (smallest format)
-a7s 'outfile' will be ANIM7 short-word
-a7l 'outfile' will be ANIM7 long-word (fastest playback)
-n No ANHD in the first frame of ANIM
16 shade grey mode is the default
The FLI file may be specified without the '.FLI' or '.FLC'
extension.
If outfile is specified, a series of 256 color ILBM's are written
in the form outfile.nnn or outfile.nnnnn, depending on how many
frames are in the file.
To write the frames as a bunch of pictures just type:
AmiFlick file outfile
Where 'file' is the FLI and outfile is the basename for the 256 color
IFF pictures.
If one of the '-a' options is used, an ANIM file will be created.
By default, AmiFlick saves a ANHD chunk for the timing information in
the first frame of the ANIM file. This is perfectly legal, but some
programs may get confused by this. If this is a problem, use the '-n'
option to leave out the ANHD in the first frame.
AmiFlick now saves pictures using the display type selected. If no
flag is given, the files will be 16 shades of grey. To save in 256 colors,
use the '-c' flag (AGA is not required when only saving the files).
'AmiFlick -s file' will just display info about the file, like how
many frames there are.
For playback, just type 'AmiFlick file'. This will give you a 16 shade
grey scale display. During playback, you can use these keys:
ESC Exits the animation.
Left Arrow Slows down playback.
Right Arrow Speeds up playback.
Space Bar Pauses playback or steps forward a frame.
Return Resumes playback.
If the screen is bigger than the display you can autoscroll with the
mouse under 2.0 and greater. The other display types available are:
'-g' 256 shade grey scale. Requires AGA.
'-c' Color. This will display the file without any conversion.
Also requires AGA.
'-h' HAM mode. In order to speed things up this looks very
blocky and has a "rainbow" effect on text. I might improve
the algorithm in the future.
Some other options:
'-v' Verbose information on the file, mainly for debugging.
'-f' Use a chunky bitmap in fast RAM. Uses more memory,
but can be much faster.
'-a5' Create ANIM5 file instead of separate pictures. This
is the most common and smallest ANIM format.
'-a7s' Create ANIM7 short-word file. Larger files, but
faster playback on accelerated machines. Not many
programs support this type. ViewTek is one program
that can be used to view these ANIM files.
'-a7l' Create ANIM7 long-word file. Largest and fastest
type.
'-b' Double buffer the display.
'-l' Load the file into RAM before playing it.
'-m<mode>' Specifies a mode to use. If 'mode' begins with '0x'
or '0X' then it is assumed to be the hexdecimal value
of the display ID. Otherwise it is assumed to be the
name associated with the mode, e.g. "NTSC:Hires"
under 2.0 or "NTSC:High Res" under 3.0. This name
must match one of the names in the display database.
The mode given should be compatible with the display
options, i.e. pick a HAM mode when '-h' is given
and don't when it isn't.
'-d<delay>' Changes the delay between each frame in 1/70's of
a second.
Files with palette changes may look messed up unless you use either the
'-g' or '-c' option. This is because of the conversion that takes place.
There isn't really anything I can do about it. Fortunately, these files
are extremely rare.
Plans for the future:
A color option for non-AGA other than HAM.
Possibly a better HAM algorithm.
Some sort of GUI. At least a file requester and a screen mode
requester.
Possibly a separate program to write FLI animations from IFF
pictures or ANIM's.
If you want to see one of these features implemented then let me know!
Also, if you want to send me a faster chunky to planar routine, I'll
consider using it in the next version.
History:
v1.05 Initial release
v1.10 Fixed double buffering under 3.0 and a few other bugs.
Now tries appending '.FLI' and '.FLC' to find the file.
Calls BestModeID() under 3.0 to figure out the mode, so
super hires and other modes will be used if appropriate.
This made the old '-H' flag obsolete as hires HAM will
automatically be used.
Screen mode can be specified. No screen requester yet, though.
v1.12 Fixed bug with uncompressed frames.
v2.01 Major improvements. Faster playback, writing in modes
other than 256 color, writing ANIM files. When writing
files, 256 color mode is no longer created by default. The
'-c' flag is needed for this.
v2.02 Minor bug fixes. Finally plays uncompressed correctly. Also
fixed HAM mode when double buffering in fast mode.
