- Textshot Description
- --------------------
-
- Textshot is a pop-up TSR (Terminate and Stay Resident) program
- designed to be a text screen counterpart to ZSoft's FRIEZE(tm),
- producing output files for use in word processors and desktop
- publishing applications. The user loads Textshot into memory,
- presses the hot key from within a character-based application,
- and a menu pops up permitting entry of a filespec and a choice of
- various file options. When the [ENTER] key is pressed, the
- screen is restored and is saved to disk in the form of either a
- 16-color or monochrome (2-color) PC Paintbrush-format .PCX
- graphics file. This file can be loaded into any application that
- accepts .PCX files or into ZSoft's PC Paintbrush(tm) itself, for
- editing. PC Paintbrush is not needed to use Textshot. Textshot
- also permits image "clipping" prior to writing an image to disk,
- as well as the optional preservation of image settings between
- pop-ups. Textshot should work on any DOS computer running DOS
- 2.11 or above.
-
- Hardware Requirements
- ---------------------
-
- Textshot will work with any of the common PC video standards.
- Specifically: MDA/Hercules, CGA, EGA and VGA. Textshot is
- intended to work only in text modes, not in graphics modes.
-
- Textshot will capture 80x25 screens (all standards), 80x43
- screens (EGA and VGA) and 80x50 screens (VGA). Screen formats of
- other than 80 columns are not supported.
-
- Since Textshot relies on a computer's internal graphics fonts for
- its output, the computer on which it's run must have, at minimum,
- a complete CGA font set. In instances where this is not the
- case, a DOS utility called GRAFTABL must be run to supply the
- "upper half" of the necessary font set. EGA and VGA cards supply
- their own complete font sets.
-
-
- Loading Textshot
- ----------------
-
- Textshot is loaded into memory by typing
-
- TEXTSHOT [ENTER]
-
- at the DOS command line. If you use an expanded memory manager,
- Textshot will function happily in high memory, leaving your DOS
- memory free for other things. For example, if you use
- Quarterdeck's QEMM, you can load Textshot into high memory by
- typing
-
- LOADHI TEXTSHOT [ENTER]
-
-
-
-
- 2
- When Textshot is loaded a message appears telling you so. As
- mentioned above, on some machines a full (256-character) ROM font
- set may not be available; Textshot checks to see before loading.
- If this is the case, you are told to run the DOS GRAFTABL utility
- before proceeding. Screen printing is disabled while Textshot is
- resident.
-
- Removing Textshot From Memory
- -----------------------------
-
- To remove Textshot from memory simply type
-
- TEXTSHOT [ENTER]
-
- from the command line, just as if you were loading it. Note: If
- you loaded Textshot into high memory through a memory manager,
- don't bother invoking the memory manager a second time to remove
- Textshot. Just type "TEXTSHOT [ENTER]".
-
- Textshot will tell you it's unloaded itself, else it will tell
- you that it CAN'T unload itself. There are many reasons why a
- TSR could be unable to remove itself from memory, but most of
- them come down to some other program, used after Textshot was
- loaded, altering the computer's interrupt table. In these cases,
- the only way to unload Textshot is to reboot.
-
- Activating Textshot
- -------------------
-
- Textshot's hot key is [PrScr] or, on some machines,
- [SHIFT + PrScr], which means hold down the [SHIFT] key while
- pressing [PrScr].
-
- If the hot key is pressed while in a graphics mode, you'll hear
- two beeps. This is Textshot's way of telling you to stop doing
- that. You will also hear two beeps if your video adapter is in
- other than an 80-column text mode. In the special case of the
- Hercules adapter, it doesn't seem to be possible to tell with
- 100% reliability when it is and isn't displaying graphics;
- sometimes, if you press the hot key while Hercules graphics are
- being displayed, instead of hearing beeps you'll see "splotches"
- appear at the top of the screen. This means that Textshot has
- failed to accurately gauge modes and you'll see what ASCII
- characters written to a graphics screen look like. Solution:
- press [ESC] to leave Textshot. Your graphics screen will be
- restored.
-
- Another potential problem lies with other programs that play with
- a computer's interrupt table, particularly the keyboard
- interrupts. Textshot attempts to be good to your computer's
- interrupt table, taking over and using no more of your computer's
- resources than it absolutely has to; but it has to have access to
- some things simply to function. If Textshot refuses to pop up,
- or if you have trouble typing inside Textshot, try changing the
- loading order of any other TSR programs you might be using. If
-
-
- 3
- you're not running any other TSRs simultaneously with Textshot
- and it still refuses to function correctly, the problem probably
- lies with the running application, and there may not be much to
- be done about it.
-
- Using Textshot
- --------------
-
- After pressing the hot key in text mode, a menu will appear at
- the top of your screen. On the first line is a prompt saying
- "Enter filespec:". This is where you type a name for your screen
- capture file. Textshot's default pop-up mode is black-and-white.
- Pressing [F6] (described a little later on) will switch you to
- color output mode.
-
- On the second and third lines are what might be called "status
- prompts", giving you your options: [ESC] and [F1] through [F6].
- Here's what they do:
-
- [ESC] Leaves the program, "pops it down".
-
- [F1] Controls image inversion in monochrome mode. Textshot
- pops up with this option set to "OFF". The correct
- setting of this toggle (called a "toggle", because
- when you press it, it goes to its opposite state; pressing once
- produces "ON", pressing again produces "OFF", and so on) can only
- be determined by examining the final printed output of whatever
- document or file you've loaded your screen image into. Some
- applications will print a normally-output ("OFF" setting) screen
- black-on-white while others will print it as white-on-black.
- What you want your output to look like will determine the setting
- of this switch. Try it both ways. Note that this option is
- disabled ("NA", for "Not Applicable" is shown) when color output
- is active.
-
- [F2] The state of this toggle determines whether dot patterns
- are used in the file to simulate, to the degree it's
- possible, what the background colors of a screen look
- like in monochrome mode. 6 of the 8 possible background colors
- have their own pattern. No patterns are necessary for white-on-
- black and black-on-white areas. Whether or not it's worthwhile
- to use color patterns will depend entirely on the nature of the
- screen you're taking a picture of and what you want the final
- output to look like. Again, give both a try. This option isn't
- available (or necessary) in monochrome screen modes, and "NA",
- for "Not Applicable", is shown in color output mode.
-
- [F3] On MDA/CGA-equipped machines, pressing this key does
- nothing; CGA fonts are all there are. On EGA/VGA-equipped
- machines, you can tell Textshot to use any font available
- in your computer by pressing this toggle. For an EGA, this means
- CGA and EGA fonts. For a VGA adapter, it means CGA, EGA and VGA
- fonts. Where you have a choice, each option represents
- tradeoffs: EGA or VGA fonts will give a higher-resolution
- picture, but at the cost of increased file size. CGA fonts
-
-
- 4
- produce the smallest output files, but with the coarsest picture
- resolution. The resolution question must be decided by what
- you're using the output files for, and what quality is necessary.
- The file size issue might become important if you're loading
- screen images into an application that already hogs most of
- memory, when a change in font resolution could mean the
- difference between using or not using a file. Also be aware that
- .PCX file editors that don't use scroll bars may be unable to
- load higher-resolution Textshot files.
-
- Textshot pops up with the font switch set to the highest possible
- resolution by default. This can be changed by using the [F4]
- key.
-
- [F4] This key preserves Textshot's toggle settings, including
- the position of the clipping box (discussed next).
- Filespecs are not preserved. The color mode (described
- under [F6], below) is unaffected by this toggle.
-
- [F5] Pressing this key enables you to tell Textshot which areas
- of your screen to save. When pressed, it causes the menu
- to (temporarily) disappear and a white "clipping box" to
- appear on your screen. The first time this key is pressed, the
- box will be as large as your screen; changing the box's shape
- tells Textshot which part of the screen you want saved -- those
- parts that are covered by the box. The clipping box is
- "inclusive", which is to say that whatever is covered by the
- edges of the box will be included in what is saved. This would
- permit, for example, collapsing the clipping box down to the size
- of a single character, if that's what you wanted, and saving that
- single character to a file.
-
- The clipping box is controlled by pressing the arrow keys. When
- [F5] is pressed and the box first appears, the arrow keys control
- the "upper left" sides of the box. The top and left sides.
- Pressing [ENTER] with the box still visible "flips" the arrow
- keys, which then control the "lower right" sides of the box. The
- right and bottom sides. Pressing [ENTER] again toggles sides yet
- again, which can be repeated as many times as necessary.
-
- Pressing [SHIFT + ARROW] accelerates the clipping box's
- movements, allowing you to "cover more territory" quickly.
-
- After setting the clipping box, pressing [ESC] makes the box
- disappear and the menu reappear.
-
- If you should want to quickly restore the clipping box to its
- default (whole screen) size without having to use the arrow keys,
- make sure the [F4] toggle is set to "OFF", pop down Textshot, by
- pressing [ESC] from the menu, and then pop it up again by
- pressing [PrScr]. The box dimensions will then be reset.
-
- Note: At least one older version of PC Paintbrush has
- intermittent difficulties with less-than-full-screen (clipped)
-
-
-
- 5
- color Textshot files. No other editor or viewer we've tried has
- any trouble with these images.
-
- [F6] This toggle controls Textshot's color mode setting.
- Textshot's default pop-up mode is monochrome, displayed as
- "B/W". Pressing [F6] changes this to "COLOR", and all
- subsequent output will be in color. Note that pressing the [F4]
- toggle has no effect on the color setting, which will remain as
- set until [F6] is pressed again.
-
- Color output files are considerably larger than an equivalent
- monochrome file, and so will take correspondingly longer to write
- to disk.
-
- Saving A Screen
- ---------------
-
- Textshot doesn't care whether or not you use a .PCX file
- extension in your filespec. So if you want your files to be
- "real" PC Paintbrush files, it will be necessary for you to give
- them a .PCX or .PCC extension.
-
- Filespecs can be as long as the available screen space. The
- cursor will stop automatically when you've reached the limit.
-
- After entering your filespec and selecting the desired options,
- pressing [ENTER] causes Textshot to restore the screen and write
- the file you've specified. Since a high-resolution file might
- take a little while to write, especially on slower machines,
- Textshot will beep when it's finished writing to disk. That will
- mean your picture is complete.
-
- Textshot does not include the cursor in the pictures it makes.
- If whatever you're using the picture for requires a text cursor,
- one can be "faked in" by loading the file into PC Paintbrush (or
- some another .PCX file editor) and drawing it. Concerning which,
- be sure to read the "Image Editing" section immediately
- following.
-
- Image Editing
- -------------
-
- As with any other .PCX-format file, screen images produced by
- Textshot can be loaded and edited inside a .PCX file editor.
- Your editor may need to be reconfigured (PC Paintbrush through
- PBSETUP) to match the color mode of the image.
-
- Depending on the "match" between Textshot's output and the
- current default aspect ratio of the .PCX file editor you load it
- into, some image distortion may be apparent. If, for example,
- you capture a VGA- or EGA-resolution screen image with Textshot,
- in monochrome mode, and load it into a CGA-configured PC
- Paintbrush, all the characters will seem elongated. Don't worry.
- These files can be edited easily enough inside PC Paintbrush.
- When, however, the images are imported into an application they
-
-
- 6
- will automatically assume the aspect ratio (the ratio of height
- to width) of the "frame" into which they're "poured". A
- computer's video screen has an aspect ratio of about 3:4. If the
- frame you pour the image into, inside your application, has this
- same aspect ratio, the screen images will look natural. If your
- Textshot images are saved using the CGA font, the resulting
- images would appear to have a "natural" aspect ratio inside PC
- Paintbrush to begin with, when it is configured for CGA.
-
- It may also happen that a Textshot image might not completely
- fill the screen of an editor. A full 25-line VGA screen image,
- for instance, will have a resolution of 640 x 400 pixels, less
- than the standard VGA graphics screen resolution of 640 x 480
- pixels. What this means is that if, after editing such a file in
- VGA screen mode, the file is saved back to disk, those blank
- areas on the bottom -- and on the right as well, if editing on a
- Hercules-configured screen -- will go with it. This is something
- to take into account.
-
- Every word processor or desktop publishing program we are
- familiar with has no trouble importing PC Paintbrush images,
- regardless of resolution or mode, and that includes Textshot
- images; mode translation is always automatic. Final judgements
- regarding hardware and software compatibility, though, as with
- any shareware product, must be yours. Please make sure Textshot
- works with everything you might need it to work with before
- committing to it.
-
- A Word About Palettes
- ---------------------
-
- In color output mode, when running on CGA- and EGA-equipped
- machines, Textshot uses the default color palette. On VGA
- machines, Textshot uses the active palette.
-
- In monochrome output mode, Textshot uses a generic, default CGA
- palette for its output, which has the virtue of at least making
- Textshot images visible in all screen modes. The monochrome
- palette has no effect that we've seen on how monochrome Textshot
- images are handled in any word processor or desktop publishing
- application.
-
- If There Are Problems
- ---------------------
-
- If Textshot has any trouble when writing the file, you'll hear
- two beeps, a message window at the top of the screen will appear,
- and whatever the problem might be is described. You are then
- asked to press any key, and the message window disappears. Press
- [PrScr] again to try the operation over.
-
- Make sure you've typed a correct pathname (a directory that
- exists) and that the disk you're writing to has enough room for
- the output file. Textshot tells you specifically about most
- common disk problems. If you see the general message "Disk
-
-
- 7
- error", though, it's something sufficiently obscure that Textshot
- (and probably you) can't do much about it.
-
- Finally, if there ever should be any difficulty in loading a
- Textshot file into an application, you might try loading it first
- into a .PCX file editor, saving it back to disk with the same
- filename, and then trying again.
-
- Tips For Getting A Good Picture
- -------------------------------
-
- As mentioned previously, the first things to try when saving an
- image is to use the toggle switches available when Textshot is
- "popped up". In monochrome mode, image inversion, the use of
- color patterns and changing the image resolution should make it
- possible to get an acceptable image under most circumstances.
- But what do you do if none of these work? This section has some
- additional ideas.
-
- If your video adapter is able, try switching to a monochrome
- display mode (VGA, MDA, or Hercules). Most programs make their
- screens differently, using ASCII characters and character
- intensity only, when running in monochrome.
-
- In cases where the color patterns aren't what you want, but you
- don't want to switch Textshot to color output, you can sometimes
- solve the problem by changing the patterns used by changing the
- top application's screen colors. Since you are dealing with
- Textshot's color patterns, remember that it doesn't matter what
- the colors on the screen look like, whether they are pretty or
- ugly; all that matters is that the color patterns turn out
- acceptably. If all else fails, try changing the application to
- sheer black-on-white, or vice versa.
-
- If you need to put something into a captured image that wasn't in
- the original, or take out something that doesn't belong, you must
- resort to a .PCX file editor. There, it will be possible to add
- cursors and to capture small bits of an original file as .PCC
- (cutout) files.
