-
- Introduction
- ============
-
- This little utility plays standard Autodesk Animator FLI and Animator Pro
- FLC files.
-
- Note that under Risc OS 2 the player only supports FLI files and only
- supports the standard 256-colour (16-palette) modes.
-
- Under Risc OS 3 however it will play FLI and FLC files, and automatically
- finds the best available screen mode, and should detect graphics
- enhancement cards if they integrate properly with Risc OS. Where 256-entry
- palettes are available these will be used if possible. It also corrects
- properly for the 6x5 aspect ratio on FLI files.
-
- Under Risc OS 3.5 (i.e. on the Risc PC) the player finds a 256-entry
- palette mode that is most appropriate - this gives true SVGA colour.
-
- For the rest of this document, where FLI files are mentioned, it should
- be taken to mean FLI or FLC files.
-

-
- Instructions
- ============
-
-
- 1) Loading FLIPlay and Starting Animations
- ---------------------------------------
-
- Double-click on the !FLIPlay icon or a file with filetype FLI (&B9F) to
- load FLIPlay.
-
- When the application is loaded, click select on the iconbar icon to
- see the FLI (if appropriate). Double-clicking on a FLI file when the
- application is already loaded automatically runs the animation. Once
- loaded, the application will attempt to play files ending in "/FLI" or
- "/FLC" as well as those of filetype FLI. Clicking select on the iconbar
- will play the last FLI loaded.
-
- Note: If FLIPLay fails to pick up double-clicks properly, and insists on
- launching a second copy of itself, then the filer has probably "seen" an
- old version of !FliPlay. If this has happened, type "Unset File$Type_301"
- at a command line prompt (press F12, type in the line then press return
- again). It is probably a good idea to delete the old version so that it
- won't be seen by the filer again.
-
-
- 2) The Iconbar Menu
- ----------------
-
- The iconbar menu allows some control over the display of animations.
- The "Options" submenu has the following items, all of which may be
- turned on and off:
-
- Display Text: For each frame, the frame number and the amount of
- time taken to process the frame (in centiseconds) is
- shown at the bottom of the display. The time delay
- does not include the time taken to load the frame
- from disc (if relevant).
- Default: Off.
-
- Override Chk: This stops FLIPlay from discarding files that don't
- come up to certain criteria. The checks include
- the file "magic number" and that the depth of pixels
- is 8bpp. I have seen a few FLIs which say they don't
- meet the 8bpp requirement, even though they do. If
- you have one of these files, select this option and
- FLIPlay will attempt to play as normal. Default: Off.
- Note: If this option is selected and a file that is NOT a
- FLI is dragged to the icon bar then the action of the
- player is undefined, and could cause your machine to
- crash. Use with caution.
-
- Grid Aspect: This option causes FLIPlay to rationalise the aspect
- ratio of animations. This is particularly useful for
- old-style FLIs which have small sized text in their
- frames. Old-style FLIs have an aspect ratio of 6:5
- which leads to problems when displaying on a screen
- whose aspect ratio is 1:1, 1:2, 2:1 etc. If this
- option is selected then the aspect ratio is adjusted
- to one that fits more easily. This means that the
- animation gets squashed or stretched somewhat, but
- the display is cleaner (and often quicker).
- Default: On.
-
- Resolution: This option has a submenu which lists all the suitable
- screen resolutions found by FLIPlay, along with an item
- "Auto". If "Auto" is ticked, then FLIPlay will try to
- find a best-fit screen resolution, picking the nearest size
- greater than or the same as that of the FLI being played.
- An individual resolution may be ticked instead of Auto,
- in which case FLIPlay will use the selected resolution.
- This is particularly useful for users with VGA monitors
- for example, or for times when the automatic selection
- picks an unsuitable screen resolution. On the Risc PC,
- the frame rate is displayed as well as resolution. On
- other machines the old-style 16-palette modes are marked
- as "low colour".
- Default: Auto.
-
-
- 3) Facilities while Playing
- ------------------------
-
- The following keys are detected by FLIPlay. The keyboard is checked
- between frames, so to have any effect a key must be held down for at
- least one frame.
-
- Key | Action
- -------+-------------------------------------
- Shift | Speed up animation
- Ctrl | Slow down animation
- Space | Pause/Release animation
- Escape | Stop animation and return to desktop
-
- Note that on the Risc OS 2 version, "Escape" has no effect, and "Space"
- causes the animation to terminate next time it reaches the end of the
- sequence.
-
-
- 4) Comments about File Loading
- ---------------------------
-
- The player attempts to read the whole file into main memory; however
- if this is not possible then the file is loaded frame by frame. Memory
- that is grabbed during playback is released back to the system when
- the animation is stopped. Obviously the playback will be quicker if the
- whole animation can be loaded - try to make sure you have enough memory
- in the "Free" and "Next" slots in the task display to hold the animation.
-
-
- 5) The FLI filetype
- ----------------
-
- The FLI filetype is &B9F. If you have any FLI files that are filetyped
- to anything else, they should be changed (an older release of
- FLIPlay used another type). Filetype &B9F has been properly allocated
- to FLI files by Acorn Computers Ltd. The filetype also covers FLC files.
