- Introduction
- ------------
-
- Can't you get that great picture of your favorite game? If your screen
- grabber is not as powerful as you need, don't worry... Capture It! has arrived
- to save you!
-
- The ordinary screen capture utilities use the keyboard interrupt to copy
- the screen when you press a hotkey. The problem is that the latest games
- intercept INT 09 (the keyboard interrupt), what prevents the grabber from
- receiving keyboard commands.
-
- Capture It! has an exclusive timer system that captures the video memory
- contents automatically every "x" seconds! You are still able to get the screen
- manually, using the hotkey CTRL-ALT-C.
-
- The program currently captures graphic screens of the following modes:
-
- Hercules 720x348 monochrome
- CGA 320x200 4 colors
- CGA 640x200 2 colors
- EGA/VGA 320x200 16 colors
- EGA/VGA 640x350 16 colors
- VGA 640x480 16 colors
- VGA/MCGA 320x200 256 colors
-
-
- How does it work?
- -----------------
-
- Capture It! is a TSR (Terminate-and-Stay-Resident) program. Once installed
- it runs in background waiting for a request to get the screen (when you press
- the hotkey or the specified time interval has been reached).
-
- While resident, Capture It! uses about 9 kbytes of memory and it CAN be
- loaded high, if you have an expanded memory manager and you need as much base
- memory as possible.
-
- The syntax is:
-
- CAPTURE <path> [ <time> <number_of_screens> ]
-
- <path> - The path where the captured screens are to be saved.
- This item is required.
-
- <time> - Time in seconds between each screen captured.
- This item is optional. If not specified, the program will
- capture the screen only when you press CTRL-ALT-C.
-
- <number_of_screens> - Maximum number of screens that should be captured
- by the program. Useful to avoid filling up your disk with
- dozens of screens! If you use the <time> parameter, you must
- specify the <number_of_screens>.
- The maximum <number_of_screens> is 255.
-
- Examples:
-
- capture E:
- captures the screen when the hotkey is pressed and save
- the files in the current directory of drive E:
-
- capture D:\GRAPHICS\PICTURES\ 10 20
- captures the video contents every 10 seconds, or when the
- hotkey is pressed. A maximum of 20 screens will be captured,
- and the files will be saved in d:\graphics\pictures\
- (DON'T FORGET THE LAST BACKSLASH!)
-
- capture OR capture /?
- will show you a brief help text.
-
-
- The program will only capture the screen if the video mode at the moment
- of the capture request is one of the valid modes (see above). Otherwise, the
- request will be noted down and, as soon as the video mode is set properly, it
- will be attended. When the screen is captured and saved successfully, the PC
- speaker beeps twice.
-
- The captured screens are saved in files named PICTxxx.CAP (where xxx is
- a number from 1 to 255).
-
- After capturing all the screens you want, press CTRL-ALT-R at the DOS
- prompt to uninstall Capture It! from memory. If you want to change any
- parameter (such as the time, or number of screens) you will also have to
- uninstall the previous installed copy, and install it again with the new
- parameters.
-
- ATTENTION! When you install a new copy of Capture It!, it starts saving
- the screens as PICT1.CAP. So, you must rename previous captured files to
- prevent the program from rewriting them.
-
-
- Now what?
- ---------
-
- | The Capture It! files are saved in an uncompressed form, to speed up the
- | capturing process, but these .CAP files are not a standard format. Well, at
- | least the CGA captured screens can be BLOADed via BASIC. :) :)
- |
- | But..... thanks to Oliver Fromme you can now convert these .CAP files to
- | the great (and well-known) GIF format.
- | There are two ways to do it:
- | - using directly the command-line driven CAP2GIF program (please
- | refer to the CAP2GIF.DOC file for instructions);
- | - or using SCReen LoaDer that lets you view and choose the pictures
- | you want to convert to GIF (if you are capturing by time you'll propably get
- | some undesired screens, so SCRLD lets you also delete files).
-
- The SCRLD syntax is:
-
- SCRLD [<path>] [/T<time>] [/F] [/L]
-
- <path> - Path where to search for the .CAP files.
- If not specified assumes the current path.
-
- <time> - Time in seconds between each picture shown.
- If not specified waits for a keypress to change file.
-
- /F - If specified, uses fade effects between screens (VGA only).
-
- /L - If specified, turns on loop. Use ESC to quit.
-
- | While viewing a picture, the following command keys are available:
- | G key - Calls the CAP2GIF program to save the picture as a .GIF file
- | D key - Deletes the picture.
- | Using the /T<time> option disables the above keyboard commands.
- |
- | PLEASE NOTE THAT CAP2GIF AND SCRLD PROGRAMS *MUST* BE IN THE SAME DIRECTORY
-
- Examples:
-
- scrld
- displays all .CAP files in the current drive and directory
-
- scrld F:\
- displays all .CAP files in the root of drive F:
-
- scrld D:\GRAPHICS\TEMP\ /T5 /F /L
- displays all .CAP files in d:\graphics\temp\ with an interval
- of 5 seconds between each one. Uses fade in and fade out effects,
- and stays in loop until the ESC key is pressed.
-
- scrld /?
- shows a brief help text.
-
- SCRLD can also read standard BASIC BSAVED screens (CGA only).
-
-
- Known problems
- --------------
-
- As you know, MS-DOS isn't a multi-task environment. TSR applications run
- in background, using hardware interrupts to have the processor's attention.
- These applications are somewhat "intruders" in the system, and may not run
- properly all the time.
-
- After capturing a screen, Capture It! may cause the system to hang up, or
- may confuse the screen display. In both cases, the first screen captured must
- be ok, so you may need to quit the game and run it again to get more screens.
- (Using a RAM drive to store the captured screens may be not a good idea if you
- have to reset the system!).
-
- If you are capturing manually, try not to use the hotkey during long disk
- transfers, specially if you are running from floppies.
-
- Only uninstall the program at the DOS prompt. If you use CTRL-ALT-R to
- uninstall Capture It! while running another program it will abort and the
- system may hang up or become unstable.
-
- Remove unnecessary TSR programs while using Capture It!. Two or more TSR
- applications may be incompatible with each other.
-
- Some programs may access the video board in a non-standard way in some
- video modes. Newer games access the VGA 256-color mode differently from the
- MCGA, what causes most of screen capture utilities to read the video information
- incorrectly. Version 2.1 of Capture It! corrects this problem. Anyway, if you
- get a distorted image of the captured screen, try using another video
- configuration in your program.
-
- | A friend reported me problems using the Write Cache of SMARTDRV (the
- | screens didn't get saved). I personally use only the Read Cache and it
- | works fine.
- |
- | Attention EGA card owners:
- | - Screens captured on EGA cards won't be correctly displayed by
- | SCRLD on a VGA card; convert them to GIF to assure compatibility.
- | - Screens captured on EGA cards with the old version 2.1 won't be
- | properly converted to GIF by CAP2GIF, so you must capture them again using
- | the new version 2.1a.
