This program is produced by a member of the Association of
Shareware Professionals (ASP). ASP wants to make sure that
the shareware principle works for you. If you are unable to
resolve a shareware-related problem with an ASP member by
contacting the member directly, ASP may be able to help. The
ASP Ombudsman can help you resolve a dispute or problem with
an ASP member, but does not provide technical support for
members' products. Please write to the ASP Ombudsman at
P.O. Box 5786, Bellevue, WA 98006 or send a Compuserve
message via easyplex to ASP Ombudsman 70007,3536
This share ware utility program: GEMCAP.COM, allows you to
capture screen images from other programs, save them in separate
GEM .IMG files, and later load them into other programs that can
read the same .IMG format such as Ventura Publisher and
WordPerfect version 5.0.
!!! Note !!!: GEMCAP.COM works with IBM CGA (color) text and
graphics modes. It will work on monochrome systems and Hercules
in text mode only. It will not work on Hercules displays in
graphics mode. GEMCAP works with EGA and VGA display adapters in
text modes and 640 x 200 graphics mode only! If the program you
wish to capture screens from uses a bitmapped display with EGA or
VGA, it probably uses a higher resolution. If this is the case,
to use GEMCAP you must reconfigure that program to use CGA
graphics mode (usually you must run through the installation
process and tell it that your display type is CGA 640 x 200).
This version (3.0) of GEMCAP automatically adjusts for monochrome
and Hercules adapters. Earlier versions used a separate program
(GCMONO.COM) for these display types.
GEMCAP is a Terminate and Stay Resident (TSR) program. When you
run it from the DOS command line, it will announce its presence
and quietly sink into the background and wait to be called into
action (when its "hot key" is pressed). When you run GEMCAP, you
must provide it with the location and starting file name to use
to store the screen images it captures. For example, you might
start GEMCAP with this command:
GEMCAP C:\SCREENS\SCREENA.IMG
Now GEMCAP will store its screens in the SCREENS sub-directory.
Note that the SCREENS sub-directory must already exist. The first
screen it saves will be called SCREENA.IMG, the second will be
called SCREENB.IMG. Each subsequent .IMG file will increment the
character in the filename just before the extension. These files
are graphic bit image files compatible with any program that
reads GEM .IMG files, regardless of whether the original screen
was in text mode or graphics mode.
To activate GEMCAP and save the current screen to a .IMG file,
you press the [Alt + .] keys (that's the period key and the Alt
key) together. You will hear a beep when GEMCAP is called. Three
beeps means it successfully wrote an .IMG file to the specified
directory. Only one beep means it was unable to create the file
(could not find the directory?). Only two beeps means it created
the file, but could not write the full 16k screen buffer, (disk
full?).
GEMCAP will detect the current video mode and adjust. It converts
text mode screens into bit mapped graphics.
Like any other TSR, GEMCAP may have compatibility problems with
other software, especially other TSR's. If you have trouble, try
installing GEMCAP by itself and adding your other TSR utilities
one at a time after you get GEMCAP to work.
New for version 3.0:
--------------------
GEMCAP converts reverse video areas of the screen appropriately.
Any color attribute combination that results in darker characters
with a lighter background will be converted to reverse video. The
following color attribute combinations on the captured screen
will result in reverse video:
any of these background With these foreground
----------------------- ---------------------
green black grey
cyan blue lt blue
brown red lt red
white magenta lt magenta
If you wish to reverse the entire screen, for example from white
on black to black on white, load GEMCAP with the following
command line argument (-R) as shown below:
GEMCAP -R C:\SCREENS\SCREENA.IMG
New for version 3.1:
--------------------
GEMCAP now will capture EGA text mode screens with 43 lines and
VGA text mode screens with 50 lines. You must decide which mode
you want when you load GEMCAP via one of the following command
line arguments: (-E) for EGA 43 line mode, and (-V) for VGA 50
line mode. For example, the command:
GEMCAP -E C:\SCREENS\SCREENA.IMG
loads GEMCAP set for EGA 43 line mode. Note that when you load
GEMCAP in this way, you cannot also capture graphics mode
screens. You must re-boot to unload, then re-load GEMCAP normally
for graphics screens.
Different sized images:
-----------------------
Note that with Ventura Publisher or WordPerfect 5.0, the size of
the image when incorporated into your document is dependent on
the size of the frame (VP) or figure (WP). For best results, you
must adjust this size (within VP or WP) so that pixels are not
truncated or compressed. Alternatively, you can change the size
characteristics within the IMG file itself.
The size of the captured image is controlled by two words in the
.IMG file. These are constants in the GEMCAP program. However if
you wish to adjust this size, you can experiment with different
values (that is if you really want to tinker around with debug).
The first word specifies the pixel size in width, the second word
specifies the pixel size in height (unit of measure is in
microns). The default values are: (in hexadecimal):
Address Value
0108 00D5 (width)
010A 01AA (height)
To make the displayed image one half the size of the default,
change these values to:
Address Value
0108 006A (width)
010A 00D5 (height)
The steps using Debug to do this are: (you enter the keystrokes
marked ^^)
DEBUG SCREENA.IMG (Load the image file)
^^^^^^^^^^^^^^^^^
E 0108 (Enter data at address 0108)
^^^^^^
XXXX:0108 00.00 D5.6A (change 00D5 to 006A,
^^ ^^ space bar between entries)
E 010A (do the same for address 010A)
^^^^^^
XXXX:010A 01.00 AA.D5 (change 01AA to 00D5)
^^ ^^
W (write the changes to the
^ file)
Writing 4020 bytes
Q (return to DOS)
^
You can experiment with other values. However, some combinations
will cause truncations of pixels when the image is displayed.
If you find a set of values that work for your application and
wish to make them the default values for all captured images,
change the corresponding values in the program (GEMCAP.COM)
itself. These values are at location 095E and 0960 (hex) when
GEMCAP is loaded into Debug. (These locations may be different in
other versions of GEMCAP).
ShareWare:
----------
The GEMCAP package is being distributed as shareware. This means
that it is not free. This means that you must pay to use it.
However, you do not have to pay to try it, test it, and to
determine if it is going to be useful to you. You are probably
familiar with the concept by now. ShareWare programs give you the
advantage of "test driving" them. The advantage to the developer
is a relatively inexpensive distribution method. For this concept
to work and keep working for our mutual advantage, you really
must register and pay for the software you actually find useful.
Please feel free to pass along a copy of this disk to others for
their trial use. But please distribute it in its original
unaltered state. The compressed arc file: GEMCAP.ARC is intended
for uploading to your local bulletin boards.
To register your use of GEMCAP, send $20.00 to Natural Software
at the address above. This entitles you to one upgrade to the
next new release for free (please specify the version you
currently have when registering). We will also send you a
description of our other software offerings (including PC-Draft
II which allow you to edit and enhance your captured images) and
provide free telephone support as needed.
If you have suggestions for improvement, or problems please write
or call.
