-
- All of these programs are compiled for 68030 and 68881 machines or better
- only. All are optimized for use on these processors.
- ----------------------------------------------------------------------
- ESCV:
-
- This is a picture viewer for OpalVision.
- It only quits when ESC is pressed.
-
- This was written so that two monitors could be used on the same Amiga
- in the following fashion: one displaying an OpalVision picture (with this
- program), the other running normal Amiga programs.
-
- ----------------------------------------------------------------------
- chainV:
-
- This program will display multiple files continuously. This means
- that only one screen will be used, and the first picture stays up while the
- second is loading, etc. for minimum black-screen between frames. Useful
- for making tapes or just viewing (easier than OpalPresents)
-
- ----------------------------------------------------------------------
- FileReqV:
-
- Uses the OpalVision file requester to display pictures (thumbnails,
- etc.) Just try it, its all point and click.
-
- ----------------------------------------------------------------------
- Iterate:
-
- This is a shell program, primarily written for script files. It
- will perform an operation on file names with incrementing numbers in them,
- such as frames of an animation (pic.1,pic.2,pic.3,etc.) for all frames in
- the sequence. The syntax is:
-
- Iterate <FILENAME> <COMMAND> <ARGS>
-
- <ARGS> should contain <FILENAME> in the apropriate place.
- The number to be iterated should be represented as the '#' character.
-
- For example, to view a series of pictures:
-
- Iterate pic.# ESCV pic.#
-
- This will perform "ESCV pic.#" until "pic.#" no longer exists.
-
- A wierd example:
-
- Iterate pic.# delete pic.#.info
-
- This will delete all the .info files for a set of pictures, until
- "pic.#" no longer exists. Note that the test file name and the actually-used
- file name are different. This means that if pic.9.info exists, but pic.9
- does not, pic.9.info will not be deleted. This would make more sence the other
- way around, but that ain't the way it works :^)
-
- ----------------------------------------------------------------------
- OpalEQ:
-
- Yet another OpalVision program. This one will plot equations for
- R,G,and B with respect to x and y as pictures, and let you save the result
- as an IFF24. Run it from WorkBench or CLI.
-
- The prompts for Red, Green, and Blue want a function F(x,y). The
- three colors have independant equations.
-
- The syntax of the equations is as follows:
-
- F(x,y) = PHRASE +- PHRASE +- PHRASE ....
- PHRASE = TERM <op> TERM <op> TERM ....
- <op> can be: *,/,or ^
- TERM = (PHRASE +- PHRASE +- PHRASE ....)
- or TERM = numeric
- numeric can be just a number (like 8, or 900, or 9.2134). There are
- two special numbers: e and pi (spelled like that, lower case).
- or TERM = <function> TERM
- <function> can be: sin, cos, tan, ln, log, cosh, sinh
- note that since <function> is performed on TERM, these functions are performed
- on the next numeric or the set of phrases in paranthesis.
- TERMs may be X and Y
-
- Examples:
-
- 4*3*2 = 24 1 PHRASE , 3 TERMs, 2<op>s
- 4*(3*2) = 24 1 PHRASE , (3*2) is a TERM: 2 TERMs
- 7*(1+2) = 21 1 PHRASE
- 1+7*2 = 15 2 PHRASEs
- 4*sinpi-pi = -pi 2 PHRASEs, 3 TERMs
- sinpi*cos0 = -1 1 PHRASE , 2 TERMs
- sin(pi*cos0) = 0 1 PHRASE , 1 TERM
- etc...
-
- You can make some pretty patterns using trig & log functions.
-
- ----------------------------------------------------------------------
- PadNum:
-
- This program expands numbers like 4 to 0004 (pads numbers with leading
- zeros). This is useful for naming things for use in animations. To run from
- the WorkBench, click once on PadNum, select all the files to pad, then double
- click the last one. PadNum will also pad .info files.
-
- Syntax:
-
- PadNum <#> <file1> <file2> <file3> ....
-
- <#> is the number of digits to pad to. For example: <#>=4 would pad
- '5' to '0005'. <#>=2 would pad '5' to '05'.
- YOU MUST NOT HAVE MORE DIGITS THAN <#>! For example: <#>=2 would be
- very confused by '103'!!
-
- <#>=0 will depad numbers. For example, '00006' would become '6',and
- so on.
-
- To decrease padding on a number, you must first depad, then repad.
-
- ----------------------------------------------------------------------
- CPY:
-
- This is another cheesy hack. The purpose of this program is to mimic
- the MS-DOS copy in which if you type "copy <filename>" with no second paramater,
- the <filename> is copied into the current working directory.
-
- For example:
-
- CPY c:memacs
-
- would copy memacs into the current directory.
-
- ----------------------------------------------------------------------
- LatchV:
-
- This is another picture viewer. This viewer copies the image into the
- OpalVision frame buffer, sets the 'latch' bit (thence the name) and then
- completely quits. The image is not stored anywhere in Amiga memory, only on the
- OpalVision. This means that: THIS VIEWER USES 0k of RAM!!! Note that there is
- no control line at the top of the screen the way there usually is. This
- picture will remain displayed even if the computer reboots (as long OpalVision
- is receiving power to its RAM).
-
- The picture will only go away when another OpalVision screen wants it.
- ( calling OpenScreen24 ).
-
- This program is only useful when running two monitors simultaneously.
-
- ----------------------------------------------------------------------
- StopLatch:
-
- This is a cheesy hack. It opens and closes a screen to clear anything
- which is currently latched in. It has the effect of clearing and closing a
- picture loaded by LatchV.
-
- Note that BackDrop24 and OpalHotKey use the 'latch' method also, and this
- program will clear them as well. They will not be expecting to be cleared by
- this program, but should not have any problem with it.
-
- ----------------------------------------------------------------------
- UC:
-
- UltimateClock. This is a tiny, powerful clock. It is pure and can be
- made resident. It is only 5k in size and minimizes memory while still
- being very processor-friendly while running. Parameters may be passed on
- the command line from CLI or as Tool Types from workbench. Parameters are:
-
- NOTIME doesn't display the time (default is to display the time)
- AMPM displays 12-hour time w/ AM & PM (default is 24 hour)
- DATE displays the date
- FASTMEM displays "Fast: #" for amount of fastmem available
- CHIPMEM displays "Chip: #" for amount of chipmem available
- SCREEN=<name> loads UC on a PublicScreen named <name>; note that <name>
- must be exactly correct (including capitalization & punctuation)
- TOPY=<coord> sets the top y coordinate for the clock window on startup
-
- ----------------------------------------------------------------------
- GetCedStat/SetCedStat:
-
- These are two programs designed to work together with Ced to make it more
- friendly. Both are about 3k in size and are pure, and can (and should) be
- made resident. I use a commodity-hotkey program to call them from
- lcommand-g for getcedstat and lcommand-s for setcedstat. Their functionality
- as is follows:
-
- load files into Ced, do whatever
- to quit, run GetCedStat. This will log the name of all the open files,
- and your position in those files
- to restart, run SetCedStat. This will restore the previous files and jump
- to where you were editing them
-
- These programs require the drawer ENVARC:CedStat to be created before
- running them. They will save the file envarc:cedstat/cedstat.
- SetCedStat will run the Rexx program envarc:cedstat/init.rexx Note that
- this rexx program must address Ced itself (see my example) because it is
- not given the host. I also use a file called envarc:cedstat/ceddefs for
- default settings, which I load in init.rexx
-
- TODO: make getcedstat call closedown.rexx and save an icon based on the
- file extension
