使用說明:

Installation
------------

To install Screen Thief for DOS, unzip the ST201F.ZIP archive
with a utility which can handle the ZIP archive format. You
should find enclosed five files:

ST.EXE
SCANCODE.COM
README.TXT
HISTORY.TXT
CONFIG.ST

Create a new directory somewhere on your hard disk and copy
these files over. You can delete the ZIP archive once you have
verified these files exist and the program runs correctly. We
suggest that you use the directory C:\ST. All later examples
assume this.

Running Screen Thief for DOS
----------------------------

To run Screen Thief with the default settings, change to the
"\ST" directory and simply type "ST". Screen Thief will then be
installed and you can run whatever program you need to grab a
screen from. To actually grab a screen, press the <CTRL>, <ALT>
and <T> keys together and you will hear a clicking noise from
your PC speaker as Screen Thief is working. The image file
produced will be in colour BMP format and given a name
consisting of the first 6 letters of the name of the program
currently being run followed by a number, eg, "FILENA01.BMP".
This file will be saved to the current directory but you can
specify a different directory when you run Screen Thief as
follows:

ST C:\CAPTURE

This will save all captured image files to the "C:\CAPTURE"
directory.

The Command Line
----------------

All of Screen Thief's operational characteristics are controlled
by command line parameters, mostly switches. Once installed, all
changes to the way Screen Thief operates can only be made via
the command line. All the various command line parameters are
covered in detail in the Reference Section of this manual, but
the more commonly used ones will be covered here. These
parameters are:

/OUTPUT Sets the Output Image File Format to either BMP, TIFF,
PCX or TXT. The default setting is BMP and the syntax of this
switch is /O:TIFF.

/MONO Enables and disables Mono Translation, ie, producing a
black and white image. The default setting is disabled and the
syntax of this switch is /M+ to enable and /M- to disable.

/UNLOAD Removes Screen Thief from memory. This is the only way
to correctly remove Screen Thief from memory; do not use
programs such as MARK and RELEASE. The syntax of this switch is
/U.

Example

To use Screen Thief to capture screens and output them in mono
PCX format to a directory called C:\PICTURES, type the following:

ST C:\PICTURES /M+ /O:PCX

Once Screen Thief is loaded in this way, you could then, for
example, change the output file format by typing the following
from the \ST Directory:

ST /O:GIF

Each time you make a change, the Screen Thief window will pop up
showing the new setup.

The SCREENTHIEF Environment Variable
------------------------------------

If you regularly use a particular setup for Screen Thief that is
not the same as the default setup, you can avoid having to type
all the command line switches each time, as in the example
above, by using an environment variable. This is a string
containing the required command line parameters that is placed
in the AUTOEXEC.BAT file using the DOS SET command as in the
example below:

SET SCREENTHIEF=C:\PICTURES /M+ /O:PCX

This will then use these parameters every time Screen Thief is
run, overriding the defaults so that you only need to type "ST"
to access your most used setup. The command line parameters will
override the environment variable so you can still run Screen
Thief differently as necessary.

The Screen Thief Configuration File
-----------------------------------

Although the Environment Variable allows you to set Screen Thief
up to a certain extent, you may have various configurations for
specific tasks that you would like to automate. This is possible
using the Configuration File. Any parameters on the command line
(or within the SCREENTHIEF environment setting) which do not
follow a switch character will first be compared against the
Configuration File. This is a simple text file such as can be
created with any text editor or word processor in ascii mode. It
must be called CONFIG.ST and exist in the same directory as the
ST executable file.

Configuration entries are implemented in the same way as the
environment string, but each is preceded with a unique name.
Each configuration must start on a new line, with a maximum line
length of 255 characters including the config name. Any
characters beyond this are truncated. For example:

REVIEWS=N:\PUB\REVIEWS\PCX /RGB+ /M- /O:PCX /K:50 /SH:OFF
BOOKS=N:\PUB\BOOKS\GRABS /RGB- /MONO /O:BMP /K:01 /SH:CL

This allows easy switching between different configurations
based solely on a customer, project or user name. However, note
that any option changed in one configuration will need to be
changed in every other configuration unless valid for all cases.

Configuration names are allowed within the environment string
and on the command line. Multiple configuration names are also
permitted, but nesting is not. This means that a config entry
cannot name another within its command line. Configurations can
also be used in isolation or in addition to other command line
switches.

If no matching entry is found within the CONFIG.ST file Screen
Thief will then attempt to use it as an image file directory
name and check its validity accordingly.

第二種 Dos 抓圖程式:
[/color][/size]

[url]ftp://mirrors.aol.com/pub/simtelnet/msdos/screen/vthf007.zip[/url]

VideoThief 0.07 20K 不錯的屏幕抓圖軟件,可以抓各種文本方式或圖形方式的屏幕,支持VGA/SVGA/VESA等,我使用后感覺效果很好.它是TSR方式的,運行后隨時可按其快捷鍵抓圖,默認是F12鍵,可用/Kxx參數修改(具體鍵值可用其自帶的SCAN命令查看),可用/R參數退出.保存的VTF格式圖像文件可以其自帶的VTFVIEW命令查看.

使用說明:

1. Supported video modes
------------------------

VideoThief supports (at least it tries to):

- standard VGA modes (both text and graphic);
- non-standard VGA X-Modes (like 376x564x256, 752x564x16, etc);
- non-standard VGA text modes (like 80x28, 80x30, etc);
- VESA BIOS Extensions version 2.0 modes, including LFB modes.

Thus, all (NO exceptions!) VESA SVGA modes should be supported. But this only
applies to _VESA_ SVGAs. For example, if you have Trident 8900 and a certain
program (or game) uses that board's specific mode, then I can't guarantee
that VideoThief will work correctly. And I won't.

2. Requirements
---------------

The minimal requirements are so modest that I'm not sure whether one'll be
able to find a machine VideoThief will not run on. Namely, what is required
is 286, VGA, DOS 3.0 and 128k of free RAM. I had not seen any CGAs or EGAs
for so many years now that I can't even imagine VideoThief's behavior with
these boards.

3. Supplied programs
--------------------

3.1. VideoThief
~~~~~~~~~~~~~~~
Filename: vthief.com
Syntax : vthief[.com] [key [key [...]]]
Keys:
/?, /h display a little help
/k<xx> set hot key scan code to xx hex (default is 58h, F12 code)
/r release program from memory
/d<dir> set directory for VTF files to dir
/p program PIC (this gives VideoThief more possibilities to
hook control)
/l LFB support mode

Register doesn't matter and slash is equal to minus, thus you're free to use
either "vthief.com -k29" or "vthief.com /K29" syntax, whatever you like.

VideoThief is a little TSR program. This leads us to the fact that first of
all it should be loaded. Then when you have run VideoThief you have two ways
to steal a picture from screen:

- press a hot key, which is F12 by default;
- run a program you'd like to explore under FreeGame and then press
<~><tab><enter><~>; VideoThief hooks int 2Fh, ax=0FEDCh, as FreeGrab
(native FreeGame Toolkit grabber) does.

With the introduction of /p key in version 0.07, which makes VideoThief use
the very same control hooking scheme as in FreeGame, this latter way is of
pure academic interest only. Should the default first way fail, just use
that /p key. Or maybe one just wouldn't run VideoThief without /p key.

Note: FreeGame Toolkit is a game cheating utility (very similar to Game
Wizard) I use sometimes. May be found on [url]www.kiarchive.ru.[/url]

3.2. VTF Viewer
~~~~~~~~~~~~~~~
Filename: vtfview.com
Syntax : vtfview[.com] <filename.vtf> [key [key [...]]]
Keys:
/i indirect video memory reading (for certain PCI-based machines)
/d set RGB-masks for direct color mode to default values

This one is a viewer for VideoThief files. While viewing, you can try
pressing the following keys:
<g> gray palette (doesn't affect HiColor/TrueColor mode)
<p> restore palette
<n> restore all registers but palette
<q> decrease logical screen width
<w> increase logical screen width
<a> move screen split line up
<s> move screen split line down
<z> move screen split line to the very bottom
<r> re-read picture data
<d> toggle double scan on/off
<+> increase scanline scaling coefficient
(font height in text mode)
<-> decrease scanline scaling coefficient
(font height in text mode)
<b> save to BMP
arrow keys scroll view window (hold shift for faster scrolling)
<pgup/pgdn> up/down one screen
<esc> exit

3.3. VTF Viewer 386
~~~~~~~~~~~~~~~~~~~
That's just VTF Viewer with 386 instructions used. It does faster BMP saving
in Direct Color modes and has a few other minor optimizations.
