                       PROFESSIONAL CAPTURE SYSTEMS

Welcome to the Professional Capture Systems (PCS). The PCS is made up of
two separate programs; one for the DOS environment and one for the Windows
environment.

The programs that make up PCS are called DosCapture and JasCapture. The
following is the guide to using both of these applications.

Required Equipment for DosCapture
DosCapture requires a 80286 or higher computer system with a VGA video
system.

Required Equipment for JasCapture
JasCapture is a Windows 3.1 or higher program. The required equipment is
the same as what is necessary to run Windows 3.1 or higher.



                               DosCapture


DosCapture is a program that will "capture" (or "take a picture of" if you
will) DOS screens.  This capture will be saved as a PCX graphics file.

Since the PCX is a standard graphics file format, the DOS screen can now be
used with most desktop publishing applications, word processors or other
applications that will work with graphics. If your application does not
support the PCX format, the image can easily be converted to another format
using a conversion program such as Paint Shop Pro. (blatant plug)

DosCapture is designed to capture screens when using a VGA card and while
running in a standard VGA 16 or 256 color mode. These VGA modes include:
   Text modes: (Characters per line x Number of lines x Colors)
        40 x 25 x 16
        80 x 25 x 16
      (??? x ?? x 16) - Extended VGA text modes, dependent on your video
                        card.

   Graphics modes: (Width x Height x Colors)
       320 x 200 x 16
       640 x 200 x 16
       640 x 350 x 16
       640 x 480 x 16
       320 x 200 x 256

You will notice that none of the "Super" VGA graphics modes are listed.
These modes are not standard from one VGA card to the next. To support them
would require that DosCapture become a much larger program, and therefore
take up more memory.

The extended text modes of "Super" VGA graphics are supported for the major
VGA chips. To support the various modes DosCapture reads a "MODE" file
called DOSCAP.MOD. We have provided various MODE files for the different
VGA chips.

   *     DosCapture ships with the DOSCAP.MOD file being identical to  *

   *     If you do not need the extended text modes you can use        *
   *   DosCapture just the way it is. Thus, you can skip over this     *
   *   section.                                                        *

   *********************************************************************

Before you can configure DosCapture, you will need to know the type of
video chip that is on your video board.  It is important that you don't
confuse this with the name brand of the video board.

There are numerous name brands for video boards (mine happens to be a XYZ
Super Ultra VGA), but the video chips that are used on these boards are
limited to just a handful of manufacturers. In order to find out the type
of chip on my video board, I first called XYZ. Guess what? XYZ is out of
business. No problem, I just opened the machine and looked at the big square
chip on the board. It said ATI. Thus XYZ was buying video chips from ATI to
build the XYZ Super Ultra VGA.

If you do not know what type of chip is on your video board, you will need
to consult your video board user's guide, or other documentation that came
with your computer.  If you cannot find this information, please contact
your hardware dealer. 

By displaying the contents of your directory (type DIR at C:\DOSCAP>), you
will notice that there are a number of "mod" files. These "mod" files are
your mode files. They are used by DosCapture to specify the type of video
chip that is on your video board.

When DosCapture is first started it will read the DOSCAP.MOD file and
support the modes that are described in this file. DosCapture ships with
the DOSCAP.MOD file being identical to GENERIC.MOD. This means that none
of your extended text modes are supported until you change DOSCAP.MOD. To
make this change, simply copy the "MODE" file for your VGA chip to
DOSCAP.MOD.  This is done as follows:

(In the example below, we will be using the file for an ATI chip. You can
substitute "ATI" with the name of the chip that your video board uses.)

At the hard drive prompt, get into the Doscap directory (CD\DOSCAP "enter")
and type in the following:
COPY ATI.MOD DOSCAP.MOD

DosCapture is now ready to run.


                    Starting and finishing DosCapture

To use DosCapture, get into the Doscap directory and type:
DOSCAP

DosCapture will now be installed and resident in your computer 
memory until it is unloaded or the machine is shutdown.

Note:  If you are running in a DOS window, under Windows, DosCapture will
be removed from memory when you shut down the DOS window. When you are done
with DosCapture, simply type the following at the prompt:
DOSCAP UNLOAD

(Note that DOSCAP must be in your path or you must be in the DosCapture
directory to type this command.) This will remove DosCapture from memory
(This does not delete the files from the hard drive.  DosCapture and the
screen captures already done will remain in the DOSCAP directory).


                             Screen Capturing

While DosCapture is resident in memory (see Starting DosCapture above),
start up the DOS program you want to do a screen capture of.  When the
desired screen is displayed, press the "ALT" and the "." keys at the same
time. You will hear one low toned beep followed by a series of clicks that
let you know a capture is in progress. When DosCapture is finished with the
capture, you will hear one high toned beep. If DosCapture does not support
the video mode that your video system is in when the "Alt" and "." keys
where pressed, then you will hear a high tone immediately followed by a low
tone.

Your capture will be saved as a PCX file and saved to the directory that
was current when you started DosCapture.  Files are named CAPxxxx.PCX
(x's representing digits) and will start from CAP0001.PCX and ascend by
one digit for each capture. When DosCapture is reloaded after being shut
down, it will scan the PCX files in the directory and begin the count at
one higher than the highest xxxx value.


                         Other DosCapture Commands

DosCapture recognizes the following commands:
  Help
  Status
  Reset

Commands are given by typing:  
  DOSCAP[space][command]

Help   -- will give you general information about Dos-Capture.
Status -- will give you information about the last capture you made. The
          information will probably be pretty useless to you, but very
          important to us if you need technical help.
Reset  -- will reset the filename that the next capture will be saved to.
          It will rescan the directory that the captures are saved to and
          determine what the next filename is that should be used. This is
          handy if you want to delete some of your prior captures while
          DosCapture is still resident in memory (the same thing happens
          when you unload and reload DosCapture, reset just eliminates the
          extra steps).



                            About the MOD files:

DosCapture is configured for your video board by reading the file
DOSCAP.MOD.  When you setup DosCapture, you should have copied the MOD
file for your video board to DOSCAP.MOD.  The following is an explanation
of how a MOD file is laid out. For the purposes of this example, we will
be using the file GENERIC.MOD.

All of the mode numbers listed in this example are standard for all VGA
boards.  Super VGA modes however are non-standard, so that a #33 for one
board may be completely different from a #33 of different board.  That is
why the MOD file of the board you are using must be copied into DOSCAP.MOD.

In a text mode, the BPP field is used to control DosCapture. It should
normally be set to 0 (zero) or left blank, but can be set to other values
to change the look of the text as it is saved out as a PCX file.  Anytime
you enter a value in the BPP field you will need to enter values for the
HRES and VRES fields.

When making changes to these files there are some do's and don'ts...
Do not remove or add the semicolons at the beginning of each line.  The
absence of a semicolon indicates that DosCapture needs this information
and can find it here.  A semicolon says that the line is descriptive and
should be ignored by DosCapture. When entering values in the fields other
than BPP, they must always be followed by a comma to separate them from
the next field.

On the following page is the file GENERIC.MOD. It not only shows the layout
of the file, but also describes the various components of the file.


;The following line is the text description of video board
GENERIC VGA CARD
;
; The following table is information that is used by DosCapture.
;
; This is a description of how the table is organized.
;
; The FIRST column is MODE#. This is the video mode that the card is running
; in. Note that the MODE# is in hexadecimal.
;
; The SECOND column is TYPE. The type must be either 0 or 1. 0 means that the
; mode is a text mode. 1 means that the mode is a graphics mode.

; The THIRD column is HRES. In text mode this is the character width in pixels.
; IT MUST BE EITHER 8 or 9. If you set it to anything else, DosCapture will
; use 8. This field does not have to be filled in text mode unless you set
; the BPP field.
; In graphics mode this is the width of the screen in pixels.
;
; The FOURTH column is VRES. In text mode this is the character height in
; pixels. This field does not have to be filled in text mode unless you set
; the BPP field.
; In graphics mode this is the height of the screen in pixels.
;
; The FIFTH column is BPP. In graphics mode this is the number of bits per
; pixel of the mode. It must be either 4 or 8. A 4 means 16 colors. An 8 means
; 256 colors.
; In text mode this field is used to control DosCapture. It should normally be
; set to 0 (or left blank), but can be set to other values according to the 
; following list:
;   a 0 means operate normally, getting all information from your video card.
;   a 1 means override the video card's character size information and take
;       the information from this mode file.
;
;
;MODE#    TYPE    HRES    VRES   BPP
0,	0
1,	0
2,	0
3,	0
D,	1,	320,	200,	4
E,	1,	640,	200,	4
10,	1,	640,	350,	4

13,	1,	320,	200,	8


                           About the Captured Screens:

Characters displayed in text modes are normally made up of 8 or 9 pixels in
width. The height of the characters vary widely. We will just talk about
the width. The same logic follows for the height (only in the other
direction).

When DosCapture captures a text screen it queries the video board for the
character characteristics. It also gets the currently used font from the
video board. These characters are turned into graphics and saved as a
graphics file.

If your video board is running in a mode that allows 80 characters across
the screen, and the character width is 8 then the resulting graphic would
have an 80 times 8, or 640 pixels wide. Thus you could then use an image
viewer to view the resultant graphic and the graphic would fit onto the
screen in a graphics mode. If instead of a character width of 8, we had a
character width of 9, the resulting graphic would be 80 times 9, or 720
pixels wide. Thus, viewing it with an image viewer, we would not be able
to see the entire width of the image at one time.

This situation is more pronounced when you start getting into the extended
text modes of 132 characters across. Although you can display 132 characters
across in text mode, it would take a graphics mode that had a width of 1056
to display the entire graphic on the screen. (This is assuming the
characters had a width of 8 pixels.)
