Installation
~~~~~~~~~~~~
System Requirements
   * 386sx or better (Pentium 90 is nice)
   * 256 colour or better graphics card (high/truecolour 
recommended)
   * 4 Megs of RAM (8 Megs or more recommended if running in 
high/truecolour)
   * Windows 3.1
   * ~300k of disk space

Installation Procedure
If you obtained your copy of ACDSee on disk, then just run 
the setup.exe program to install.  Otherwise, you need to 
follow the following steps:

1)	Copy the ACDSEE files anywhere you like
2)	Create an icon for ACDSEE.EXE in Program Manager
3)	If you do not already have CTL3DV2.DLL in your 
        WINDOWS\SYSTEM directory, then install the copy included in 
        the ACDSee distribution with the DOS prompt command, 
		expand ctl3dv2.dl_ c:\windows\system\ctl3dv2.dll
	Then delete the CTL3DV2.DL_ file from your ACDSee 
        directory.
4)	You will probably want File Manager associations for 
        image files with ACDSEE.EXE  This will allow you to view 
        pictures from File Manager by simply double-clicking on 
        them.

Running ACDSee
~~~~~~~~~~~~~~
You can start ACDSee from the Program Manager by double-
clicking on its icon. You will immediately be presented with 
the Image Browser dialog where you can browse your 
directories for images to look at.

If you have made a File Manager association between image 
files and ACDSee, you can also start ACDSee from the File 
Manager by just double clicking on an image file. 

You can supply one or more image files as the command-line 
arguments to ACDSee.  You can even use wildcards.  e.g., 
acdsee.exe *.jpg would start ACDSee and have it slideshow 
all the files in the current directory.

Note:	When ACDSee is run in this manner, pressing Escape 
will exit the program, rather than take you to the Image 
Browser.  The reason for this is  to avoid confusion when 
using the Spawn Viewer option

Image Browser
~~~~~~~~~~~~~
This is where you can pick an image to open.

Image Browser - Current Directory
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This bar contains the current directory the image browser is 
looking into.  You can change the current directory by 
clicking on one of the directories or drives in the File 
List.

Image Browser - File List
~~~~~~~~~~~~~~~~~~~~~~~~~
This is a list box that contains a number of entries.  There 
are several different kinds of entries in the file list:

Parent Directory [..]
Current Directory [.]
Files
Subdirectories
Drives

You can change the currently selected entry by:
*	clicking on another entry with the mouse button
*	moving the selection bar with the cursor keys
*	pressing a lowercase letter, which will take you to the 
next entry starting with that letter
*	pressing an uppercase letter, which will take you to 
        the previous entry starting with that letter

You can select several entries by:
*	clicking on one entry with the mouse and dragging down 
        or up the list
*	holding down shift and moving the selection bar with 
        the cursor keys or by clicking on another entry with the the 
        mouse
*	pressing Shift-F8 to enter Multiple Selection Mode.

Various actions may be taken on the selected file(s) with 
the Buttons below the file list.

Adjusting The Amount Of Space Available For The Preview Area
You can control how much room is available for displaying 
the Image Preview as follows:

Horizontal	adjust the horizontal size of the Image 
                Browser window.
Vertical	adjust the vertical SplitBar

Image Browser - Split Bar
~~~~~~~~~~~~~~~~~~~~~~~~~
	The split bar is an invisible control located in the 
space just below the File List and above the Buttons and 
Preview Area.
	You can adjust the relative amount of vertical space 
alotted to the File List and Buttons/Preview Area by 
clicking on this control and dragging it up and down.  The 
File List, Buttons and Preview Area will automatically 
resize themselves accordingly.

Viewing Window
~~~~~~~~~~~~~~
This is where the images are displayed.  If ACDSee is 
viewing more than one image, they will be shown in slideshow 
mode.

If the image is larger than the size of the ACDSee window, 
you can pan (scroll) the image 

The View Window (and the ACDSee icon, when ACDSee is 
minimized) is Drag-and-Drop aware, which lets you view 
images by dragging them from File Manager onto ACDSee.

Pop-up Menu Commands

You can activate the pop-up menu in the Image Viewer by 
clicking anywhere in the window with the right mouse button.

	Next Image
	Prev Image
	Stop Slideshow
	Resume Slideshow
	Browser
	Options
	Reload Image
	DecompressionTime
	About
	Help
	Exit

System Menu Command
Always On Top

Image Panning
~~~~~~~~~~~~~
	When the mouse cursor appears as a hand, the image is 
larger than the size of the Image Viewer window.  To pan 
(scroll) the image being viewed, click anywhere on the image 
and drag it.  Alternatively, use the cursor keys to move the 
image within the window.
	This can be quite fun, especially on an accelerated 
video card.  For those of you that don't like to wait, the 
scrolling feature can be used even while the image is being 
decompressed!

SlideShow
~~~~~~~~~
	When more than one image is selected for viewing, 
ACDSee enters SlideShow mode.  Here you can look at each 
file in sequence by using the Prev and Next menu commands.

Registration
~~~~~~~~~~~~
ACDSee is ShareWare
	ACDSee is "ShareWare".  This entitles you, the 
customer, to try out the software for up to 30 days without 
obligation to pay for it.
	Shareware (non-registered) ACDSee is a "full" version.  
This means that the same capabilities available in the 
registered software are present in the non-registered 
software.  In fact, the non-registered software includes a 
bonus feature - the shareware nag box
	If you use ACDSee beyond the 30 days, you should 
register it.  Registration entitles you to free upgrades to 
the software, which is nice.  

How To Register
	Before you register, please take a look at the 
Licensing section of this help file.

	You may register by credit card over the phone, via 
Compuserve, or by money order.  In any case, the cost of 
registration is a modest $US 15.  

	If you are part of a business and wish to use several 
copies of ACDSee within your company, greatly reduced site 
licensing rates are also available.  Please call 1-800-414-
ACDS for a quote.

	CD-ROM publishers please contact us if you are 
interested in including a special non-shareware CD-ROM 
version of ACDSee on your CDs.

Unlocking the Software
	You will receive a notification of registration from 
ACD Systems which contains your personal registration name 
and number.
	First, bring up the Reigistration Dialog by first 
invoking About dialog box, then clicking on the Register 
button. (Or you can select Help|Register from the View 
Window menu.)
	Enter your name in the registration dialog.  Be sure to 
type your name exactly as it appears in your notification, 
as capitalization, spaces and punctuation are all taken into 
account when computing your registration number.
	Now enter your personal registration number, and select 
Register  If all is well, ACDSee will respond with a message 
thanking you for your registration.  Otherwise ACDSee will 
complain that your name and number don't match, and you will 
have to correct the information.

        when the height of the Image Browser window is changed, 
        rather than moving proportionally
o	The Image Browser buttons will align into a single 
        column when there is enough vertical space
o	Executable is smaller and loads faster
o	Moved all Viewing Window options into a single dialog 
        box
o	Retired the Chunk Decompression option - the 
        decompression rate (lines per tick) is now inversly 
        proportional to the image width
o	Fixed bug which sometimes caused ACDSee to crash after 
        changing Image Browser options
o	Fixed bug that arose in version 1.22 where ACDSee 
        didn't close itself properly when lauched in Image Viewer 
        mode
o	Popup Image Browser menu now works properly in a 
        multiple column file list

Version 1.22 - Mar. 1995
+	Created the nifty on-line help file (using ForeFront's 
        ForeHelp software)
+	You can now independently turn on/off the display of 
        associations, file sizes, image dimensions and descriptions, 
        as well as control whether the file list is multi-column or 
        single-column
+	Added option to start up in the directory that ACDSee 
        was in when it last exited
+	Added option to show image dimensions only on fixed 
        drives, which should bring some relief to CD-ROM owners
+	Added option to *not* cache image dimensions in 
        descript.ion, which seemed to annoy some people
+	Added pop-up menu to Image Browser file list
+	Image Browser options moved into a separate dialog box
+	The location of the split between the Image Browser 
        file list and the buttons/preview area may now be changed

        Viewer window position
+	ACDSee now accepts wildcards (eg, '*.jpg') on its 
        command line
+	The unregistered ACDSee nag box appears less frequently 
        while ACDSee is viewing images, (although you shouldn't 
        notice any difference, right?   ;-)
o	The font in the Image Browser's file list may now be 
        set by editing ACDSEE.INI (FontName=fontName)
o	ACDSee now recongizes JPEG files with the extension 
        ".JPE"
o	ACDSee now runs properly under Windows NT and Windows 
        '95 as a 16-bit Windows application (tested under version 
        3.5 of NT and Windows '95 final beta)
o	ACDSee no longer "looses your place" in the file list 
        after deleting a file
o	Files can now be selected/deselected with the space bar 
        (using the Shift-F8 selection mode)
o	Fixed bug in v1.21 that caused ACDSee to complain that 
        "Dropped file could not be read" when a single image was 
        dragged and dropped into the View Window.
o	It turns out that the smaller executable of version 
        1.21 was the result of accidentally excluding a resource 
        from the EXE.  (ACDSee generated the missing resource 
        automatically at run-time, however this increased the 
        application startup time.)  The resource has been re-
        included so that the EXE is larger, but loads faster.
o	Reading in large directories is much faster now
o	Fixed a bug that caused ACDSee to show blank images 
        and/or crash when another application deleted files that 
        ACDSee was attempting to slideshow
o	Fixed a bug that sometimes caused ACDSee to delete file 
        descriptions created by another program while ACDSee was 
        running in the same directory
o	Fixed a bug that prevented ACDSee from recongizing 
        descript.ion files with upper case file names
o	When you switched from ACDSee to another application 
        and deleted the descript.ion file, and then switched back to 
        ACDSee, it would not realize that the descript.ion file was 
        deleted and not update its file list accordingly
o	Fixed bug that potentially caused ACDSee to report the 
        wrong associated application for certain file types
o	ACDSee now displays only one delete confirmation box 
        for a multiple file deletion
o	With image information turned off, ACDSee was still 
        trying to write the image information into the descript.ion 
        files, which caused a rather long wait when changing 
        directories or quitting the program.  My apologies 
        particularly to owners of CD-ROM drives!
o	CTL3DV2.DLL now distributed in compressed format, to 
        avoid the warning message if the user forgot to delete it.

Version 1.21 - Jan. 1995
o	Uses CTL3DV2.DLL instead of CTL3D.DLL
o	Executable is a lot smaller
o	Fixed bug that caused images in the root directory of a 
        drive to not be recognized properly
o	Fixed bug that caused ACDSee to crash if the root 
        directory of a drive contained no files or subdirectories
o	Having two top-level windows was the source of some 
        grief for the Windows window manager.  Now the Image Browser 
        and View Window are both child windows of an invisible main 
        window.
o	Targa (TGA) images which are RLE-compressed are now 
        read properly
o	Thumbnails are now generated properly for Grayscale 
        Targa (TGA) images 
o	Fixed bug that caused thumbnails to sometimes be 
        displayed in full size and colour
o	ACDSee will now spawn itself to view an image even if 
        no association has been made to ACDSee for that file type

Version 1.2 - Jan. 1995
+	Replaced the Open Image dialog with the Image Browser 
        window, providing
	+	optional quick image preview
	+	coloured filenames
	+	optional 4DOS descriptions and image information
	+	4DOS descriptions may be edited
	+	window may be resized
	+	option to spawn a new copy of ACDSee for each 
        image opened
+	allows launching of other application via file 
        associations
+	Added slideshow support
+	Added option to automatically resize the viewing window 
        or not
+	Added Always-On-Top option
+	Added Full-Screen option
+	Added Drag-and-Drop support
+	The view window may now be scrolled using the cursor 
        keys
+	Added GIF interlaced support, and GIF preview
+	Added PCX support
+	Added TGA support
+	Added BMP support (no OS/2 or RLE right now)
+	Added new quantization/dithering routines:  No 
        dithering, Ordered Dithering and Floyd-Steinburg dithering 
        (except for JPEG Ordered, which is hard-coded into the 
        decoder)
+	Added Floyd Steinberg dithering process to the 
        thumbnails when the source image is highcolor or truecolor 
        (except to JPEG, which is Ordered and hard coded into the 
        decoder)  No dithering for paletted images right now.
o	Removed support for scroll bars in the view window
o	Fixed a bug in the registration dialog box that 
        prevented people with long names from registering

Version 1.1 - Dec. 1994
+	Added support for non-interlaced, single-image GIFs
+	Added JPEG quick preview feature
+	Added the #colours in the image to the title bar 
        display
o	Improved the registration system
o	ACDSee uses less memory now
o	Changed the halftone palette system

Version 1.01 - Dec. 1994
o	Fixed bug that caused ACDSee to crash when multiple 
        copies were running simultaneously (the problem was that I 
        was grabbing a device context
        and holding it during compression, which is a no-no -- 
        windows only supports five concurrent device contexts)
o	Vast improvement in image quality when displaying 
        grayscale JPEG's in 256-color mode.
o	Reorganized code to make it easier to add other image 
        formats, such as GIF (yes, it's coming...).

Version 1.0 - Nov. 1994
o	Initial release.

Possible Future Enhancements
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
o	support for Photo CD, TIFF, Amiga IFF and other file 
        formats
o	faster decoding of all image formats
o	faster JPEG colour preview
o	2-pass quantization support for 256 colour users
o	faster dithering
o	copy image to clipboard function
o	optional command buttons and status bar for the Image 
        Viewer window
o	image info - display image format information
o	ability to copy, rename and move files

Frequently Asked Questions
~~~~~~~~~~~~~~~~~~~~~~~~~~
1)	Where can I find the latest version of ACDSee?
The latest version of ACDSee is available via anonymous 
internet ftp from:
	wuarchive.wustl.edu in pub/msdos_uploads/win_graphics

2)	ACDSee says, "ACDSee will not run in less that 256 
colours".  What do I do to make it run?
This message indicates ACDSee has determined that Windows is 
running in fewer than 256 colours.  If you know your video 
card is capable of  displaying 640x480x256 or better (most 
512k + cards can do this) then you can change your video 
driver with Windows Setup (in the Main program group in 
Program Manager).

3)	When I run ACDSee, I get a nasty message saying "Cannot 
find CTL3DV2.DLL" and it won't run.
See the note about CTL3DV2.DLL in Installation procedure 

4)	When I run ACDSee, I get a message saying "This program 
uses CTL3DV2.DLL, which is not correctly installed."
The file CTL3DV2.DLL exists in the same directory as ACDSee.  
This file must be moved into the WINDOWS/SYSTEM directory 
for ACDSee to work properly.

5)	ACDSee is generating hidden files in all my 
directories.  What are they for?
These are 4DOS description files.  They hold file 
descriptions and information about the images in the 
directory.  You can delete them, if you wish, with File 
Manager by selecting View|By File Type... and checking Show 
Hidden/System Files.  To prevent ACDSee from generating 
these files, use the Dont Cache Image Dimensions option.

5)	Will there be a 32-bit version?
A 32-bit version of ACDSee is under development.
