CyberShow Professional Version 4.2 (c) by Helmut Hoffmann 1995
======================

This is an universal shareware picture viewer/slideshow/presentation
program (incl. PhotoCD support, transition effects, ...) 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.

               for pictures now) incl. multiple icon selection for pictures/drawers
	     + Multiple file selection support in picture/path/pattern requester
             + Extended information window (now incl. file size, file comment)
             + Now ignoring .info files on default
             + next/previous picture now also selectable with space/backspace keys
New in V3.2: + support for RLE-compressed BMP images (8Bit or 1Bit)
(see version history for earlier versions...)

Supported picture file formats for loading:

1) IFF-ILBM (all standard formats 1 to 8Bit, EHB, HAM6, HAM8, 24Bit)
2) PhotoCD (Base format 768x512 or 512x768 (portrait); linear 24Bit RGB)
3) JPeg (color and greyscale)
4) PPM/PGM/PBM (P1&P4 b&w, P5 grey, P6 color)
5) QRT (also known as dump format by PD raytracers as POV-Ray)
6) Targa (RLE compr.&uncompr. 1/8/15/16/24/32Bit; incl. interleaved)
7) PCX (compr.&uncompr. EGA1-4Bit, VGA 8Bit grey/Colormap and 24Bit)
8) BMP (uncompr. 24Bit RGB,1Bit,4Bit or 8Bit Colormap; RLE compressed 8Bit,1Bit)
9) TIF (packbit-compr./uncompr. Motorola formats 24Bit RGB, 1-8Bit grey/Colormap)
10) EGS7.x window icons
11) DEEP (compr.&uncompr. IFF-DEEP 24Bit and 32Bit formats)
12) YUV (color 1:1:1, 2:1:1, 4:1:1 and greyscale)
13) VLAB raw (color 1:1:1, 2:1:1, 4:1:1 and greyscale)
14) RGB (IFF-RGB: RGB8 and RGBN compressed; RGB5 uncompressed)
15) HHsYUVSq sequence format (sequential or random access)
16) IFF-PBM (DPII) format
17) ACBM (IFF-ACBM: 1 to 8Bit, EHB, HAM6, HAM8)
18) FBM (8Bit grey/Colormap and 24Bit)
19) Sun raster (uncompressed formats for 1Bit, 8Bit grey/ColorMap and 24Bit)
20) MacPaint (b&w compressed 1Bit format; datafork only)
21) HHsXRL formats (1-8Bit ColorMap incl. HAM6/8, 8Bit grey, 24Bit RGB compressed)

and all picture and animation DataType formats under OS3.x.

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 or XiPaint
3) JPeg (variable compression rates)
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 and transition effects.

+ 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 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.

+ Pictures can be scrolled (with cursor keys or scrollbars) in their
  resizeable windows.

+ 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 (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 (are there any missing?)
 + zooming functions for magnification or downscaling)

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; smaller pictures
				are shown centered in the window; you can still
				resize the window manually. This presentation mode
				supports transition effects which are selected
				as default for TrueColor/HighColor windows
				(use Effects or NoEffects to manually control this)
       SlideShow		Show pictures on screen (no window borders); this
				works best if you select your own Screenmode. On
				Workbench or Public screens you will still have
				a depth arrangement bar on default (you can instead
				select a backdrop window with another option).
				As there are no scrollbars, you can only scroll
				with the cursor keys in SlideShow mode. The usual
				menue functions are still available.
				The slideshow mode supports transition effects
				which are selected as default on TrueColor/HighColor
				screens	(use Effects or NoEffects to override)
       BackDrop			Backdrop window for SlideShow on WB or Public Screens
       Black			For small pictures fill unused screen or
				window areas with the foreground pen (usual
				black) instead of background (usual grey); in
				SlideShow mode on private screens black is
				always used and even specifed as background to
				make presentations better e.g. for Video recording
       Effects			Select transition effects for window presentation
				or slideshow (effects are selected by default for
				TrueColor/HighColor screens only; use this option
				to get effects also on 2 to 256 color screens)
       NoEffects		Disable transition effects; if you use this option
				together with the Effects option, the effects will
				actially be disabled, but the usual palette locking
				for 2 to 256 color screens will remain active
       IgnoreErrors		Do not show requesters for unreadable files;
				they will instead be quietly ignored
       (Please note: SlideShow and presentation windows are not available
        in the CyberShow-Light version!)

  b) CLI usage: You can specify multiple pathes/pictures/patterns in the CLI
     command line, e.g.:
      CyberShow ram:#?.jpg tmp:#?.iff "CD1:Photo_CD/Images"
     Picture parameters can be included in " for better compatibility.
     This should work with directory utilites as well (I checked it with DirOpus
     4.12A+: E.g. specify CyberShow {F} as DOS command for your CyberShow button).
     There are many other parameters available as command line options, which are
     usually identical to the Workbench ToolTypes. Type CyberShow ? to get a list
     of parameters. Here are the additional parameters (incl. abbreviations):
	DS=Downscale (number)	-> see WB tooltypes above
	NR=NonRecursive		-> see WB tooltypes above
	SM=Screenmode (name)	-> see WB tooltypes above
	PS=PublicScreen (name)	-> see WB tooltypes above
	Icons			-> see WB tooltypes above
	Request			-> see WB tooltypes above
	PW=PresentWindow	-> see WB tooltypes above
	SL=SlideShow		-> see WB tooltypes above
	BD=BackDrop		-> see WB tooltypes above
	Black			-> see WB tooltypes above
	Effects			-> see WB tooltypes above
	NoEffects		-> see WB tooltypes above
	IE=IgnoreErrors		-> see WB tooltypes above

If you just start CyberShow without any picture parameters, a file/path/pattern
requester appears. With this you can specify a directory (path) with an optional
pattern or select one or multiple pictures (by holding shift during the selection).
You can select a new file/path/pattern by using the "New Directory" menu entry
at a later time (it will be shown automatically after displaying all files
if you select the Request option).

In any case subdirectories will be searched automatically if you don't restrict
searching by a pattern to one directory or use the NonRecursive option.

Default is to load pictures in full size. With the "Scaled-Loading" menue
or Downscale option you can select to load all pictures in reduced size.
For many file formats this downscaled loading will be significantly
faster. Please note that the pictures will be in small form in memory, thus
save or transfer operations will save or transfer the images in small form.

To show pictures as slideshow instead of windows, it is best to specify
a screenmode as well: E.g.
  cybershow #?.jpg SlideShow ScreenMode "PICCOLOSD64:800x600x16M"
You can also use the slideshow as backdrop e.g. on the WB screen.
SlideShows and PresentWindow presentations will by default use transition
effects on TrueColor/HighColor screens. You can switch them off with
the NoEffects option or select them with Effects for palette oriented
screens. Please note that effects on palette oriented screens can
be quite slow (due to this fact some effects are only available on
TrueColor/HighColor screens) and that the palette will be locked for
all pictures. This can lead to reduced displaying quality if you have
many pictures with different colors. On TrueColor/HighColor screens such
problems can not occur.

To advance to the next picture use the "Next Picture" menu entry
(Shortcut Amiga N), press the space bar or press the close button of the
picture window. During displaying the next picture will already be loaded.
Since version 2.0 you can now scroll or resize the window or select another
function while the next picture is preloaded (due to technical restrictions
of some file formats this is partially not available if pictures are not
stored line by line, e.g. FBM24, ACBM, DataTypes, vertical PCD images, YUV,
VLB, HHsYUVSq; during the color conversion phase you can still scroll and this
phase is often longer than the loading time unless you load from floppy disk).
Scrolling can now be performed with cursor keys or the scroll bars (scroll
bars are not available in slideshow mode).

You can also go back to previous pictures with the "Previous Picture"
menu entry (Shortcut Amiga P) or by pressing the backspace key.

If you try to select the next picture (or previous picture) before
automatic preloading has finished, the window title will inform you about
the already loaded part of the picture (in percent).

For the currently displayed picture you can get an information requester
by selecting the "Picture Info" menu item (Shortcut Amiga I). It includes
the name, dimensions, file format, file size, file comment and number of
frames (for animations). The file format string often includes the color
depths or other variation informations as well. For pictures loaded with
any DataType, the file type is "DTxx" with xx being the color depth.
For animations loaded with DataType the file type is "DHxx".

You can quit the program with the "Quit" menu item or by pressing the Esc
key in the picture window (or screen), by pressing Ctrl-C in the CLI or
sending a Ctrl-C signal to the task.

The "About" menu function gives an information requester (which includes
the personal registration information if you are a registered user with
a correctly installed keyfile).

Fast direct transfer and saving/conversion (not available in demo version):

You can directly transfer the image in full 24Bit quality very fast to
important image processing and painting programs (see transfer menu).
Currently supported applications: ImageFX, XiPaint and ArtEffect/PicoPainter
Unfortunately Photogenics seems to currently have no suitable port to
allow such transfers (at least upto V1.2). I hope this will change in
the future.

Transfers should at least be possible to ImageFX 1.5/1.6, ImageFX 2.x,
EGS-ImageFX, XiPaint 3.x, all versions of ArtEffect and PicoPainter 1.3.
For ArtEffect/PicoPainter you can transfer the image into a picture
project window or into a brush.

Please note that pictures will always be transferred in their loaded
size. If you have selected the downscaled loading, the pictures will
be transferred in small form.

The same restrictions apply to the save functions which can be used to
convert the currently loaded image into one of several formats (see
above for list of supported save formats). All pictures are saved as
24Bit images. This is not dependent on the screenmode. The size which
has been used for loading will be the size in which it is saved. For
JPeg saving you can select the quality between 50% and 95% in 5% steps
with a sub menu.

Problems with loading specific file formats?

If you have difficulties viewing a picture in one of the supported
file formats (or DataTypes) and you are sure that you have enough
memory left, check the following:

a) File systems: Some PD/ShareWare/Commercial add-on or replacement
   file systems are buggy (e.g. they do not support some rarely used
   DOS functions properly). Try to copy the picture to a standard
   device (e.g. RAM:) and to view it from there. If this works, you
   know that your specific file system is buggy. I really reccommend
   to only use official Commodore file systems (e.g. the AmigaOS3.1
   CD-Filesystem) in case of difficulties.

b) DataTypes: Some DataTypes are instable and can crash on certain
   pictures with odd dimensions or incomplete pictures. I have no
   influence on this.

Requirements
============

Any Amiga with

+ OS3.0 or higher
+ some memory (about 4MByte Fast-RAM should be enough for normal use)

For displaying in TrueColor/HighColor quality you also need

+ cybergraphics.library V40 or higher and a suitable graphic board
  (Cybergraphics is a Workbench emulation/True color software extension
   which is usable in conjunction with several graphic boards as the
   Cybervision, Piccolo, SD64, Picasso, Retina-BLTZ3, Spectrum, Domino.
   It is Copyright by Thomas Sontowski and Frank Mariak.)

Shareware modalities
====================

The unregistered demo version of CyberShow has an important restriction:

All pictures will be shown in greyscale only in the demo version!!!

Anyway, I have designed the loading functions so that the speed is the
same as with color loading so that you can check the real speed of my
fast loading functions, but please note: on screens with less than
15Bit color depths the displaying speed of the greyscale pictures could
be higher than that of color pictures due to the fact that the color pen
allocation is different. I have no influence on this; to see the real
speed, try it on HiColor/TrueColor screens (if you have Cybergraphics),
as no color pens are needed and it makes no difference if a greyscale
or true color image is displayed. If you want to see how the color
allocation works with 2 to 256 colors, take a look at CyberTVPlayer,
my freeware animation player for HHsYUVSq sequences (a sample sequence
is included in the CyberTVPlayer archive). CyberTVPlayer uses the same
color reducing functions as CyberShow.

Some other functions are also not available in the demo version (e.g.
fast direct transfer functions and save functions).

Currently you can choose between two levels of registration:

a) CyberShow Professional (incl. SlideShow/Presentation functions)

   Shareware fee 30DM (in europe) or 25US$ (outside europe); other
   currencies possible (see registration form)

b) CyberShow Light (without SlideShow/Presentation functions etc.)

   Shareware fee 20DM (in europe) or 18US$ (outside europe); other
   currencies possible (see registration form)

   Please note that the CyberShow-Light registration will probably only
   be available upto 31st October 1995 and if at all possible you should
   only register for the Professional version to encourage further
   development of high quality shareware products. New functions in
   future versions of CyberShow might be available to Professional users
   only as well.

To register send the filled in and signed registration form (included
in this archive) to my address together with the money as banknotes,
a cheque or international postal money order:

My address:             Helmut Hoffmann
			Rubensstrasse 4
			D-41063 Moenchengladbach

			Germany

Users in germany can also transfer money to my account (No bank transfers
from outside germany!!).

You can currently contact me by EMail (no registrations by EMail!):

		hhoff@pool.informatik.rwth-aachen.de

After registration you will receive a keyfile and the latest version of
this program. The keyfile will enable you to use future demo versions of
this program as full version. The processing of your order can take
some time. Usually it will be very fast (only a few days), but under raw
circumstances it could take some weeks.

Registered users might get another advantage: If I decide to port my
picture management software EGSPhotoAlbum for Cybergraphics and standard
Amigas, registered CyberShow users can register for a lower price.
The fast loading functions of CyberShow are the same as thoose in
EGSPhotoAlbum Professional 5.x.

Special note for Photogenics users: In addition to CyberShow you can order
my FastUniversalGioModule for a small add-on fee (see registration form).
The loader module is based on the same functions as CyberShow (only
JPeg is missing as this did not bring any significant speed advantage).

Special note for ImageFX users: In addition to CyberShow you can order
my FastImageFXModules for a small add-on fee (see registration form).
The loader module is based on the same functions as CyberShow (only
JPeg is missing as this did not bring any speed advantage). All other
loading functions were faster on my configuration or were not available
with the standard loaders. A saver module for some formats is also included.

                     during the next picture is loaded
                    Window position will now be left unchanged for newly
                     opened windows if possible; the scroll position will
                     be left unchanged between pictures of identical size

Special Thanks
==============

My special thanks go to:

 Kermit Woodall from NOVA-Design for providing me with ImageFX-EGS and ImageFX.
 Thomas Dorn for providing me with XiPaint.
 Almathera for providing me with Photogenics.
 Alexander Pratsch for providing me with ArtEffect (successor of PicoPainter).
 Without this support the fast direct transfer functions or loader modules
  would probably have been impossible.
 Thomas Sontowski and Frank Mariak for making the TrueColor/HighColor
  Workbench possible.
 The "Independent JPEG Group" for providing the portable C source code
  for JPeg compression/decompression. The JPeg functions are based on
  this code (This software is based in part on the work of the independent
  JPeg Group).
 and to all registered users of CyberShow, esp. thoose who reported bugs
  or made suggestions...

Hard- and Software used for developing
======================================

This program is written in pure Assembler (using the german assembler
O.M.A. 2.0). Only the lowlevel JPeg functions have been implemented
in C (based on the portable C source of the Independent JPeg Group)
and compiled with the german MaxonC++ 3.0 system.

My development system is:

Amiga 3000/030/25MHz / 18 Megabytes RAM / OS3.1

4MByte Piccolo SD64 (64Bit) graphics board (running in Zorro III-mode).

This program was tested with enforcer and mungwall running.
