- !Projector Version 1.18
- =======================
- (FOR NOTES ON LATEST VERSION SEE END)
-
- This projector is for playing Ace film format
- films, produced with either:-
- Euclid+Mogul (3D)
- Paint+Splice (2D pixel based)
- Draw+Tween (2D object based)
-
- This is a Multidocument/Multiwindow version.
- You can pop up a menu in the film window.
- Most operations are obvious (try them!).
-
- In Freeze mode you can single step the film
- by using Select/Adjust on the window.
-
- The New View option (under Misc) plays another
- instance of the film, but uses the same copy in
- memory, so is different from actually loading a
- film twice.
-
- Using an Obey file you can load a set of films, and
- optionally set them to play immediately in a rolling
- demo. The syntax is either:
-
- [<Projector$Dir>] Film Film Film ... [-Cn] [-Fn] [-R[n]]
-
- E.g:
- Films.Humans Films.LitLogos Films.Chess -C2 -R
-
- The -C and -F flags control the count for repeating
- each film and the flyback count per frame respectively.
-
- Or:
- <Projector$Dir> -L {[-Cn -Fn] Film}...
-
- E.g.
- WimpSlot -min 800k
- <Projector$Dir> -L -C1 -F8 Films.Chess -C2 -F2 Films.Flag
-
- Note that the usual controls over each film are available.
- Pressing S will skip to the next film irrespective of the
- repeat count.
-
- The -L flag forces the films to be loaded one at a time
- rather than all in one go for the -R flag, and allows a
- longer rolling demo from a Hard disk.
-
- Please send examples of good films together with
- permission (or not) for distribution to:
- Ace Computing, 27 Victoria Road, CAMBRIDGE, CB4 3BW.
-
- Details about Euclid, ArcLight, Mogul, Splice and
- Tween can be also be obtained from the same address.

- Tony Cheal Jan-Feb 1990
- =======================
-
- 1.07 (Jul? 1990) The projector now intelligently
- plays films in new modes which match the film's
- mode in bits-per-pixel and aspect ratio.
-
- 1.08 (Aug 1990) New key - Ctrl-B in full screen
- mode puts the keyboard into a mode which will
- always single step the film forward one frame.
- Another Ctrl-B will get it out of this mode.
-
- Now includes a new EuclidX to play Lempel-Ziv
- compressed films. Note that if a Euclid module
- is already running which does not have Lempel-Ziv
- decompression (i.e. prior to 2.12) then Lempel-Ziv
- films will still cause errors.
-
- 1.09 (Sep 1990) Minor bug-fix for button clicks.
-
- 1.10 (Sep 1990) Supremecy bits now preserved in 4bpp modes.
-
- 1.11 (Oct 1990) Pause at film starts during an
- -L type Rolling demo can now be forced by using
- using a new -W switch. The switch is cancelled
- by a new repeat count, or another -W.
-
- 1.12 (Feb 1991) International version.
-
- Made more (indeed completely?) resiliant to errors
- in Redraw code, e.g. Unknown compression/expansion
- technique.
-
- -E flag to cause exit from a rolling demo. E.g.
- <Projector$Dir> -L Films.Chess -C2 Films.LitLogos -E
-
- 1.13 (Mar 1991)
-
- New "I" control when in full screen mode to turn
- on Interlace when taking the film out of freeze mode.
- The same control can be used to turn off the interlace
- when freezing.
-
- Fundamental bug in frame timing, which only showed
- up on very fast machines (e.g. 540) has been fixed.
-
- 1.14 (May 1991)
-
- Added new Delay function on IconBar menu. Sets the delay
- for on-desktop playing.
-
- 1.15 (July 1991)
-
- Single frame films are loaded Frozen.
-
- 1.16 (Oct 1991)
-
- Corrected sprite allocation calculation (some big films wouldn't load).
- Added 'Y' flag (on keyboard and for rolling demo) to set YoYo, and made
- films yoyo off desktop if they were yoyo-ing on desktop. Still not
- completely correct (see next para.)
-
- Added count to Roll option on iconbar. Each film is repeated the relevant
- number of times. If Yoyo-ing the count is the number of times the film
- reaches the end. (So Roll 2 would give 2 forward/1 backward playing.)
-
- A flag can be set inside the film itself to start yoyo-ing when the film is
- loaded (bit 2 of byte 36), but this currently has to be set by steam. Its
- action is inverted by using the -Y flag when loading films. The -Y flag stay
- in force until a second -Y flag.
-
- Added -D flag for rolling demos to stop people coming up to the stand and
- stopping them! Commands in off screen mode have to have the shift key
- pressed at the same time when this flag is set. (So Shift-Escape is needed
- to stop the films.)
-
- 1.17 (Nov 1991)
-
- Added a new key in Full screen mode. X will turn on a cursor (like the
- counting cursor) which will report the coordinates of the top left of the
- cursor itself. Note that the key which was used to initiate the cursor is
- also used to switch it off.
-
- 1.18 (May 1992)
-
- Alterations made to allow Iota/Ace new Film format to run (this format is
- essentially an extended Ace Film).
-
- 1.19 (Jun 1992)
-
- Small changes to set border colour on Iota films/speed up ColourTrans table
- calls.
-
- 1.20 (Jul 1992)
- Bugfix due to the changes in 1.19!
-
- 1.22 (May 1993)
- Don't know what I did for 1.21!
- New option for 'From file'. Next set of films will be slaved directly from
- file, giving unlimited film length. File loading can be switched on/off
- using the projector flag -O in a command line.
