- FLICK FLI-format Animation Viewer v1.4 5 Jan 1995
- --------------------------------------
-
-
- This program plays FLI/FLC-format bitmapped animation files on any
- OCS, ECS, AGA or EGS Amiga running OS2.04 or higher. FLI/FLC-format
- files are produced by Autodesk Animator (Pro) and Autodesk 3D Studio
- on a PC, as well as by other programs.
-
- The files in this archive may be distributed anywhere provided they are
- unmodified and are not sold for profit.
-
- Ownership and copyright of all files remains with the author:
-
- Peter McGavin, 86 Totara Crescent, Lower Hutt, New Zealand.
- e-mail: peterm@maths.grace.cri.nz
-
-
- FEATURES:
- ---------
-
- Supports EGS Spectrum and other third-party graphics cards via EGS
- libraries. Runs in a draggable, overlappable window in this case.
-
- Uses AGA 256-colour screen when AGA is available.
-
- Extra-Half-Brite screen (EHB) allows reasonably good colour
- approximation on OCS/ECS Amigas.
-
- 16-colour screen (COLOUR4) allows reasonably good colour approximation
- on OCS/ECS Amigas in hires (and it's usually faster than 256-colour).
-
- Falls back to EHB (lores) or COLOUR4 (hires) when EGS or AGA are not
- available.
-
- Uses an Intuition-friendly Screen. You can flip it to the back, or
- drag it down in the usual way, while an animation is playing.
-
- Plays either from ram or directly from disk. Falls back to disk play
- when not enough ram is available.
-
- Works with any size or resolution FLI/FLC file.
-
- Supports double-buffering. The latest OS3.0 double-buffering
- functions are used if possible.
-
- Uses state-of-the-art chunky-to-planar routines. Achieves typically
- 90 frames/second in WARP mode on an A4000/040. Detects and uses Akiko
- chip on CD32 for typically 40 frames/second.
-
- Uses ASL file-requester.
-
- Runs from either icon or shell. Uses icon tooltypes for options (i.e,
- WorkBench Icons/Information... menu item).
-
- Source code is included, so if something doesn't work you can fix it.
-
-
- OPERATION:
- ----------
-
- I've tried to make it easy to use in many different ways.
-
- Just double-click the FLICK icon and select an anim to play from the
- requester.
-
- Alternatively you can set up project icons for your anims (e.g, with
- IconEdit).
-
- Options can be specified either on the commandline or via icon
- tooltypes.
-
- From the SHELL or CLI, the syntax is:
-
- FLICK FILE/M,DISK/S,RAM/S,ONCE/S,COLOUR/S,EHB/S,COLOUR4/S,GREY/S,
- EGS/S,ROM/S,DBUF/S,WARP/S,NOAKIKO/S
-
- If you don't specify a file, the file-requester pops up.
-
- You can specify a list of files, separated by spaces. However #?
- wildcards don't work.
-
- Options are:
-
- DISK: Plays from disk (i.e, plays while reading).
-
- RAM (default): Plays from RAM (i.e, loads first, then plays).
-
- ONCE: Play once, then quit. (Default is to loop).
-
- COLOUR (default): AGA 8-bitplane 256-colour mode.
-
- EHB: Extra-Half-Brite 6-bitplane mode.
-
- COLOUR4: 4-bitplane 16-colour mode (usually faster).
-
- GREY: 4-bitplane 16-grey-scale mode (usually fastest).
-
- EGS: 3rd-party graphics card via EGS libraries.
-
- ROM: Uses graphics.library WritePixelArray8().
-
- DBUF: Double-buffer. Default is not to double buffer.
-
- WARP: Plays real fast. Default speed is what anim says.
-
- NOAKIKO: Do not use Akiko even if it is available
-
- The options COLOUR, EHB, COLOUR4, GREY and EGS are mutually exclusive.
-
- The ROM and DBUF options may be used in conjunction with COLOUR, EHB,
- COLOUR4 or GREY, but they have no effect with EGS.
-
- The ROM option might be useful with non-EGS 3rd-party graphics cards,
- via mode-promotion. Without the ROM or EGS options, FLICK writes
- directly to the Screen's bitmap, which might crash with some cards.
- The ROM option makes FLICK 100% RTG friendly.
-
-
- KEYBOARD AND MOUSE CONTROLS
- ---------------------------
-
- To quit an animation, press ESC, Q, q or CTRL/C, or click the right
- mouse button. (In EGS mode, the right mouse button must be clicked
- inside the window.)
-
- Keys F1 through F10 can be used to change the speed as follows:
-
- F1 as fast as possible
- F2 60 frames per second
- F3 30 frames per second
- F4 24 frames per second
- F5 15 frames per second
- F6 12 frames per second
- F7 10 frames per second
- F8 5 frames per second
- F9 1 frame per second
- F10 at rate specified in FLI/FLC file
-
- The + and - keys can also be used to speed up and slow down an
- animation while it is playing. Each press doubles or halves the
- current requested speed.
-
- Note: If FLICK cannot run as fast as the requested speed, you may have
- to press - several times before you see any slowdown.
-
-
- USING EGS LIBRARIES
- -------------------
-
- FLICK tries to open a window on the default EGS screen if EGS
- libraries are installed and no overriding options are given.
-
- FLICK requires an 8-bit EGS screen. If the default EGS screen is
- 24-bit or another depth, FLICK gives up on EGS and falls back to
- COLOUR, EHB and COLOUR4 in that order.
-
- To prevent that from happening, either:
-
- o Change the default EGS screen to depth-8 with EGS-ScreenMode
- Prefs; or
-
- o Define the FLICK environment variable as the name of a valid
- EGS screen mode, e.g, SETENV FLICK "LEGSa:VGA 640x480".
- FLICK will then open a new screen using that mode, instead
- of using the default EGS screen.
-
- EGS Speed is dependent on the EGS driver installed. A GVP Spectrum
- card is very fast. The Amiga AGA driver is very slow. If your EGS
- libraries are installed with the AGA driver, use the COLOUR option or
- tooltype to request an Amiga screenmode.
-
-
- OTHER FREELY DISTRIBUTABLE FLI PLAYERS FOR THE AMIGA:
- -----------------------------------------------------
-
- Other FLI viewers I know about are:
-
- Flit 1.0 by John Bickers.
-
- AmiFlick v1.05 by Garrick Meeker.
-
- Flip 1.66 by Dominik Tonn.
-
- EGSFlick 1.2 by Frank Neumann
-
- These should all be available on Aminet or orion.etsu.edu. Flip v1.66
- is often faster than FLICK v1.3, but it requires AGA.
-
-
- WHY IS IT SO SLOW?
- ------------------
-
- Have you tried the WARP option or pressed F1 yet? The default is to
- play at the speed defined in the anim file, which is usually slow.
-
- Have you got EGS libraries installed with the AGA driver? That will
- be very slow. Disable EGS (e.g, by moving the EGS monitor icon to
- storage and rebooting) or use the COLOUR option or tooltype with
- FLICK.
-
- EGSFlick 1.2 is faster than FLICK because EGSFlick decompresses all
- the frames into RAM first. FLICK saves memory by decompressing on the
- fly.
-
- Well actually I think FLICK is quite fast for what it does.
-
- FLI-format is exactly the wrong format for the Amiga. That is,
- everything is stored internally in "chunky" format, but the Amiga has
- its graphics video-memory arranged in "planar" format. All known
- algorithms to convert between chunky and planar format are very, very
- slow.
-
- FLICK incorporates several different c2p algorithms optimised for
- different situations. All the routines are now CPU based. There are
- separate c2p routines optimised for the 68000, 68020, 68040 and Akiko.
- All c2p routines attempt to update only parts of the display that
- changed since last time.
-
- If you manage to improve the algorithms significantly, or find a
- faster one, please let me know.
-
- For EHB, COLOUR4 and GREY modes, the program makes an extra
- translation for every pixel. In EHB and COLOUR4 modes the program
- performs a long calculation to recompute the translation table every
- time the colour map changes. (Note: FLICK does not recalculate the
- currently displayed frame with the new palette, so if the next frame
- changes only part of the screen then the part which is unchanged will
- appear in the wrong colours. Fortunately this doesn't happen very
- often, and it never happens in COLOUR mode on an AGA Amiga.)
-
- If you really want to see a FLI-format or FLC-format file played fast,
- convert it to an Amiga anim format first. The shareware program
- MainActor is excellent for that. Also AmiFlick can write IFF files,
- and some of the commercial anim utilities, like ImageFX, can convert
- directly from FLI to anim.
-
-
- BUGS:
- -----
-
- Bugs? What bugs? Oh well, maybe the following can be construed as bugs:
-
- Anims with lots of colour map changes don't play correctly in EHB,
- GREY or COLOUR4.
- Can't select multiple files from file requester.
- Can't use #? wildcards on commandline.
- Stdio output window is ugly.
-
-
- THANKS:
- -------
-
- Thanks to James McCoull for his c2p routines (which I have modified
- slightly).
-
- Thanks to Patrick van Logchem, Dominik Tonn, John Bickers and others
- for suggestions and testing.
-
-
- DISCLAIMER:
- -----------
-
- It seems to work for me. Tested on:
-
- A3000 + 40MHz Warp engine + Spectrum EGS
- A4000/040
- A500 + Mega Midget Racer
- CD32 + SX-1
-
-
- HISTORY:
- --------
-
- v1.0 19 Dec 1993
-
- First release.
-
-
- v1.1 27 Jan 1994
-
- Fixed some minor bugs (missing "break" statements which fortunately didn't
- do any harm apart from wasting some memory).
- Fixed bug where some structures could be left allocated and asl.library
- left open after certain error conditions.
- Use V39 Intuition-friendly double-buffering functions when possible.
- Added ROM option to use graphics.library WritePixelArray8().
- Significantly sped up the chunky2planar routine.
- Got FLC-format support working for 640x480 and 480x300 resolutions.
- CTRL/C aborts the whole program, not just return to the file requester.
- Added 68040-optimised c2p routine.
- Added COLOUR4 mode.
- Compiled with SAS/C 6.51.
-
-
- v1.2 19 Feb 1994
-
- Fixed bug where mode did not fall back to COLOUR4 for FLC files on ECS
- Amigas.
- Worked around SAS/C 6.51 bug in fseek/fread that caused some disk
- anims to fail.
- Disk-play now reads a frame at a time instead of a chunk at a time.
- Improved c2p routine for Chip-only machines by eliminating a mem copy.
- Fixed bug where dbuf messages weren't replied to after strange error
- conditions.
- Added support for FLI/FLC files of any resolution.
- Wrote a much faster routine for when only part of the display changes
- each frame (and made it the default). This sped up many anims
- by a factor of 2 or more.
- Added NOCOMPARE and NODBUF options.
-
-
- v1.3 4 Jan 1995
-
- Changes almost too numerous to list.
- Replaced all c2p routines with new, much faster, OCS-friendly ones.
- Removed NOCOMPARE option, no longer uses blitter at all.
- Added support for EGS libraries, run in a window.
- Added + and - keyboard controls.
- Default is now single-buffered instead of double-buffered.
- Added exact-speed feature and WARP option.
- Right-mouse button quits.
- Auto-detect and use Akiko chip.
- Rewrote some of the chunk decoding routines in assembly.
- Added tooltype support.
- Greatly sped up code for ROM option.
- For ROM option, allocate bitmap in more system friendly way for gfx cards.
- Major code restructuring in general.
-
-
- v1.4 5 Jan 1995
-
- Fixed bug which sometimes caused crashes when double-buffering.
- Fixed bug which caused corrupted displays with Akiko and depth < 8.
- Added NOAKIKO option (handy for comparing speeds on a CD32).
