- OKSCRN.COM is an experiment. It is a program which should be able
- to do screen captures of Text or Graphics screens. I have tested
- it on my CGA screen and it seems to work. I would like verification
- that it works on a variety of other screen types.
-
- INSTALLATION: OKSCR.COM is installed by entering OKSCR followed
- by any valid DOS command. OKSCR is not technically a memory resident
- program. It loads itself temporarily while another program is
- executing and then unloads itself when the program is done. Although
- OKSCR is a very small file (even smaller after I ICE'd it) it grabs
- a healthy chunk of memory (about 74k) so it can process any graphics
- screen.
- Typically you would enter a command such as:
- OKSCR BRUSH
- which would load in PC PAINTBRUSH or:
- OKSCR GIFVIEW MARILYN.GIF
- which would load in a GIF Viewer and a picture of Marilyn Monroe.
- (please note that you have to have PC Paintbrush, Gifview and Marilyn
- before you can load them, The point is that OKSCR loads another program,
- any program, and cannot operate alone.)
-
- Once you have loaded OKSCR and a program you may, at any time
- trigger the screen capture by pressing the Alt and Left shift keys and
- holding them down while you tap the O key (letter O - not zero).
- OKSCR will attempt to identify the graphics mode that you are in and
- grab a screen accordingly. If you are in text mode the program will
- grab a text screen and save it.
-
- SPECIAL INSTRUCTIONS FOR HERCULES GRAPHICS MODE: Hercules is the
- single non-standard mode that does not use BIOS calls to set the
- screen. It is difficult to be sure that a program is using
- Hercules mode and impossible to tell which of two screens is active.
- By pressing Alt Left-Shift H you can grab the Hercules Graphics
- screen 0 as a PCX file. If you are not in Hercules graphics mode,
- you still get a PCX file, but it is not usable.
-
- SUPPORTED VIDEO MODES:
- Text:
- modes 2,3 and 7
- Graphics:
- modes 4,5 and 6 - CGA
- modes D and E - EGA
- modes 10 and 11 - VGA
- modes 25 and 50 - 640*480 Paradise and Tseng Labs
- mode 40 - AT&T 640*400
- mode 43 - Hecules Screen 0
-
- I will be adding to the list and including color.
-
- TEXT FILES: If you are in a valid text mode, OKSCR will produce
- a file named ########.CAP on the current disk and directory. The
- CAP files are timestamped by using the current time as the name of
- the file. This allows many screen captures in a session. The file
- is an ordinary ascii text file. All screen attributes are stripped and
- a carriage return and line feed is added every 80 characters and an
- end of file marker is added. You can use these files directly in most
- word processors.
-
- GRAPHICS FILES: The graphics files produced are in PC Paintbrush
- format and are readable by OPTIKS and some other conversion programs
- for inclusion as a graphics file. They are readable by Ventura.
- The file produced is a black and white file (color will follow in
- a few weeks). The extension of the files produced is PCX and the
- name is a time stamp in order to uniquely produce many files.
-
- TIPS: You may make OKSCR.COM "resident" by entering:
- OKSCR COMMAND
- Enter EXIT at any DOS prompt in order to "uninstall" OKSCR.
-
- You may convert the .CAP files to .PCX files with OPTIKS by
- loading the files as TEXT and saving them as PC Paintbrush files.
- This way you can accurately present text screens in Ventura as
- a graphics file, including all of the box drawing characters.
- If you decide to try this, do not let Ventura do the scaling to fit,
- always use an even amount scale factor such as 2 by 2 to prevent
- strange distortions and loss of detail.
-
- VIRTUAL LAST WORD. I am still messing with this program and don't even
- have a version number. If something strange happens, you machine
- might lock up (I haven't gotten it to lock up on me lately, but
- my users are much more inventive than I am.) Until you are sure
- that OKSCR works correctly, don't do anything non-recoverable.
-
- REAL LAST WORD. Please don't send money. For the time being, OKSCR
- is free. I remain the copyright owner and I will not allow it to
- be distributed with commercial products or sold except for disk
- copying service who charge a nominal fee. I hope to be updating and
- improving OKSCR and at some point will charge for it. Please do not
- call me. I am never home an I cannot return phone calls on a free
- product. I can be reached at PC Rockland BBS. I do not mail diskettes
- except for the complete OPTIKS commercial package. Do not mail me
- diskettes with return postage with requests for mailings.
- I am very moved that people want to support shareware, but I have
- found that running the business is a full time job and I already
- work all day and teach at a local college evenings. I program
- shareware because I like to, not because I expect to make any
- money. When the money aspects start getting in the way of programming
- I have to put my foot down. I thank you for your support. Please
- use OKSHR and enjoy it. I hope it helps you.
