/* Visage_Slideshow for Directory Opus 5 and Visage.
By Leo 'Nudel' Davidson for Gods'Gift Utilities
email: leo.davidson@keble.oxford.ac.uk www: http://info.ox.ac.uk/~kebl0364/
Visage is (C)1995 by Magnus Holmgren (Internet: cmh@lls.se or cmh@augs.se,
Fidonet: 2:204/204.6) and available on Aminet or from Magnus' WWW Page
(http://www.lls.se/~cmh). Many thanks to Magnus for a great picture viewer,
especially the rare random-slideshow and xpk-decrypt options.
$VER: Visage_Slideshow.dopus5 1.5 (8.1.96)
NOTE: This script _requires_ DOpus v5.11 or above.
This simple script will call "Visage" to display a slideshow of all
pictures in the source-lister's path, in random order. Optionally, a
requester will appear so that you can give it a password to xpk-decrypt the
pictures with, if required.
To change the default amount of time pictures are displayed for, alter the
"Visage_Delay" variable below (time in seconds).
This script has the ability to disable SwazBlanker for the duration of
the slideshow. For this to work you must have a program called "handlecx"
in your path and you must enable it by having the "DisSwaz" switch below
as "YES". If you don't run SwazBlanker or don't have handlecx, make sure
you set it to "NO" or things might not work.
Call as:
------------------------------------------------------------------------------
ARexx DOpus5:ARexx/Visage_Slideshow.dopus5 {Qp} {s} [NoPass] [<Time>]
------------------------------------------------------------------------------
Turn off all switches.
"[]" means this part is optional.
Arguments must be given in the order shown.
NoPass: Tells the script not to prompt for a password (no decryption).
<Time>: Override the default delay-time (seconds) between pictures.
v1.00 -> v1.01 - Very minor tidying up.
Now checks to make sure the DOPUS.x port exists.
v1.01 -> v1.2 - Now uses Show() instead of ShowList(). (Thanks Stoebi)
Style Guide compliant version numbering and $VER string.
v1.2 -> v1.3 - "NoPass" option added to surpress password prompt.
Added the ability to change the default delay time on
the command line.
v1.3 -> v1.4 - Paths with a space at the beginning or end will now be
handled correctly, for what it's worth.
v1.4 -> v1.5 - Now has the ability to disable SwazBlanker for the
duration of the slideshow. See above for details.
