CyberShow Professional Version 5.1 (c) by Helmut Hoffmann 1995
======================
This is an universal shareware picture viewer/slideshow/presentation
program (incl. PhotoCD support, transition effects, zooming ...) and
converter for all Amigas with OS3.0 and higher which can
* display images in TrueColor/HighColor in Cybergraphic windows or screens on
Workbench, custom screens or public screens with at least 15Bit color depths
including transition effects for slideshow or presentation windows
* display images in reduced color (upto 256 colors) on any WB screen, custom
screen or public screen, including AGA, ECS, OCS and usually WB-Emu graphic
board screens as well (e.g. EGS-Emu, CyberGfx-Emu, ...)
It has many special features which make it a flexible, fast and comfortable
multi-purpose tool.

-> Important! If you have any difficulties viewing certain picture types
-> (e.g. PCX, PhotoCD, DataTypes, JPeg etc.) directly from CD-ROMs (while viewing
-> the same pictures copied to disk works), you have encountered a CD-ROM file
-> system problem. I have heard of difficulties with several third party file
-> systems. I recommend to use only one of the following CD-ROM file systems:
-> 1) Original AmigaDOS OS3.1 CD-ROM file system
-> or 2) AmiCD-File System V1.15 or higher (older versions are probably NOT usable)
-> see section "Important" below for more details.
For animation formats (HHsYUVSq and animation datatypes) the first frame is shown
(for playback of HHsYUVSq animations you can use my freeware program CyberTVPlayer).
Please note: The GIF format is not internally supported for legal reasons, but
due to the DataType support GIF loading should be possible if you have a
suitable DataType (with a fast GIF DataType loading is usually still faster
than with many other viewers which directly support GIF!).
Supported picture file formats for saving:
1) IFF-ILBM 24Bit (compressed and uncompressed)
2) IFF-DEEP 24Bit (uncompressed)
This format is used e.g. by TVPaint, XiPaint or Photogenics
3) JPeg (variable compression rates and optimization)
4) PPM-P6
This format is used by the PBM image processing software
5) QRT
6) Targa 24Bit (compressed and uncompressed)
7) HHsXRL TC24 format (compressed lossless and lossy)
This format is esp. designed for raytracing pictures, which should be
compressed lossless or with nearly invisible losses. Compression is usually
better than IFF-ILBM or Targa compression.
Highlights of CyberShow: Why should you use this viewer
+ flexible presentation of your pictures in windows or on screens incl.
slide show function or window presentation mode with transition effects.
A selectable delay time allows automatic presentations...
+ Fast zooming (magnification upto 1:4 and reduction upto 4:1; use + to zoom
in and - to zoom out; * to go to standard size) and fast scrolling functions
(cursor keys or scrollbars)
+ All loading functions (except JPeg: This software is based in part on the work
of the independent JPeg Group) have been written in Assembler and optimised for
extremely high speed. Loading will usually be upto 5 times faster than with
comparable viewers... An exception to this is the JPeg format, which is
written in C and based on the usual code, so that it will be about the same
speed as other viewers.
+ Automatic preloading: The next picture is loaded while you view the current
picture; you can now also scroll or zoom the picture or use other functions
during preloading of the next picture; this reduces waiting time to a minimum
+ Supports true color viewing on Cybergraphic public screens (or custom screen)
of at least 15Bit color depths
+ Supports reduced color viewing on screens with 2 to 256 colors, including
most kind of WB emulations on graphic boards. A special color selection
scheme is used for good quality and good speed.
+ Support of nearly all commonly used image formats (incl. PhotoCD) and
additional DataTypes for even more formats
+ Can view single files, group of files (supporting patterns) and
even directory trees (automatic search of subdirectories); multiple
picture arguments can be passed by CLI, Workbench or selected with file
requester. Images will be shown in alphabetical order (ordered by complete
path name).
+ Optional downscaled loading for faster access and less memory usage
(selectbale as CLI parameter, WB Tooltype or by menu function)
+ Can go back to previous images as well
+ Information window for picture can be opened including name, dimensions,
file type, file size, file comment and number of frames (for animations)
+ Fast direct transfer of images to famous image processing and painting
programs (currently ImageFX, XiPaint and ArtEffect/PicoPainter are supported;
transfers to other programs could be included if more developers/dealers
would support me and more programs would have sufficient interfaces)
+ Save function to convert pictures into some 24Bit file formats (JPeg, IFF, ...)
(More to come if enough users register: Possible future expansions e.g.
+ more spectacular transition effects for slideshow/presentation mode
+ support for more file formats)
Using instructions
==================
Configuration: Usually CyberShow will show the pictures in windows directly on
the default public screen (usually the Workbench). To make use of other
screens, private screens or to present the pictures as SlideShow etc,
you can select options as CLI parameter or by Workbench Tooltypes.
A screenmode or public screen name can also be specified by the
environment variable "CyberShowScreen":
a) Custom Screen: If you want a screen to be opened for CyberShow you should
set an environment variable with the screenmode, e.g.:
SETENV CyberShowScreen "NTSC:HighRes Interlace"
You can specify all kinds of screenmodes for Amiga screens, emulation
screens of graphic boards and TrueColor/HighColor screens for Cybergraphics.
In any case the screen will be opened with the max. depth which is available
for that mode. Please note that the screenmode name is case sensitive!
Take a look at the Prefs/Screenmode program's list of screenmode names
to see what is available. If you specify an unknown screenmode name or
the specified screenmode can't be used for some reason the program will
use the default public screen (after an information requester).
Alternatively you can specify a CLI parameter "Screenmode": e.g.
CyberShow Screenmode "NTSC:HighRes Interlace"
This parameter will override the ENV: variable as well as a
PublicScreen parameter.
This is also available as tooltype for WB start (e.g.
Screenmode=NTSC:HighRes).
b) Named Public Screens: If you want to make CyberShow use a non-default
Public Screen, you can also specify this with the ENV: variable, e.g.:
SETENV CyberShowScreen "*CoolScreen"
To distinguish between a screenmode and a public screen name the *
character has to be specified before the screen name. To find out the
public screen name of your applications, look into their manuals! The
screen title of the public screens is often NOT the public screen name.
If the named public screen can't be used (if it is not found or private)
then the default public screen is used (after an information requester).
Alternatively you can specify a CLI parameter "PublicScreen": e.g.
CyberShow PublicScreen "CoolScreen"
This parameter will override the ENV: variable. Please note that the *
has not to be specified for the CLI parameter. If you also specify a
Screenmode parameter, the PublicScreen parameter will be ignored.
This is also available as tooltype for WB start (e.g.
PublicScreen=CoolScreen).
To save the screenmode or name specification for automatic use after booting,
just copy it from ENV: to ENVARC: (or use the WB Tooltype).
If you want to use the program on the default public screen again, just
SETENV CyberShowScreen "" or delete the variable from ENV: or from ENVARC:
for permanent effect (or delete the Tooltype).
Parameters: CyberShow now accepts multiple picture/path/pattern and
configuration parameters both from Workbench and CLI.
a) Workbench usage: To specify pictures, you can multi-select one or several
pictures or even drawers by holding shift and selecting with the mouse
before double clicking.
Another method is to make icons for the pictures and specify "CyberShow"
complete with it's path as default tool.
Other options can be specified as tooltypes in the icon for WB start.
The options are similair to the CLI options. Take a look at the icon
to see the available parameters which are enclosed in parentheses to
make them inactive.
DefaultPath=path Provide default path for path/pattern/file
requester after startup or for save requester
Downscale=number Select downscaling with factor 1:number
(number range 1 to 16 supported in increments of 1)
NonRecursive Switch off recursive subdirectory search
Screenmode=name Select screenmode name for private screen
(Overrides ENV:CyberShowScreen)
PublicScreen=name Select named public screen
(Overrides ENV:CyberShowScreen)
Icons Do not ignore .info files. This is only useful if
you have some Icon-Datatype and want to take a look
at the icons of files. By default, .info files are
now completely ignored. Please note that in
addition to this option you might have to remove
the ~(#?.info) pattern from the file requester if
this is used.
Request Show file/path/pattern requester after
displaying all files
PresentWindow Leave window size unchanged between pictures;
window will open at screen size; sma
