Thanks for checking out CropGif.

This program will allow you to crop fragments from existing GIF
files. The fragments will be written to new... smaller... GIF
files.

Unlike other GIF cropping programs, this one doesn't involve the
use of any tricky measurements. It works like the cut and paste
functions of a paint program. It requires that a Microsoft
compatible mouse driver be present before it will work, as the
mouse does all the work.

In order to make the program work reasonably fast and in a
decent amount of memory, the image you'll get to work with
will not be a full colour one. Instead, CropGif will show you a
dithered monochrome version of your source GIF file. However, the
destination file will have the same colours as the source file
did.

Because the CropGif display works with monochrome graphics, it
can be used with pretty well any display card. It supports:

- CGA (ugh!)
- EGA
- VGA
- Hercules monochrome

and, of course, anything which can emulate these modes. It should
automatically sense your display card type.

Here's how the beast works. Let's assume that you have a GIF file
called ANGELA.GIF, from which you wish to crop a fragment to be
called FACE.GIF. We'll allow that the fragment will probably
contain Angela's face, although the program itself probably won't
care.

Note that FACE.GIF, the destination file, will be created by
CropGif. ANGELA.GIF, the source file, will not be modified in any
way.

Making sure that you have previously loaded your mouse driver...
and that, prior to doing so you have indeed remembered to buy a
mouse... you would type the following:

CROPGIF ANGELA.GIF FACE.GIF

In fact, you can leave off the .GIF extensions, as CropGif
assumes these. You will see a beg notice... please don't merely
ignore this... with the program status below it. CropGif will
begin by loading ANGELA.GIF. It will then proceed to dither
ANGELA.GIF, that is, to create a temporary black and white
version of it. When this is complete, your screen will pop into
graphics mode and you'll see the dithered image.

The dithered image probably won't look too great, but don't worry
about this. It's only used to help you decide what to crop out,
and has no effect on the final image.

Move the mouse cursor to the upper left corner of the part of the
image you want to crop out. Hold down the left mouse button and
drag your mouse until the bounding rectangle encloses everything
you want to crop into FACE.GIF. Release the mouse button.

If you discover that you've selected the wrong bit of the picture
you can click your mouse to erase the bounding rectangle and try
again.

When you've got the right part of the picture enclosed, hit the
End key and your screen will return to text mode. The beg notice
will return... once again, please don't ignore this... and you'll
see a line at the bottom of your screen informing you that your
fragment is being written to FACE.GIF.

When this is done, you'll return to the DOS prompt.

If you change your mind and decide you don't want to crop a
fragment once you're in graphics mode, just hit Esc to return to
DOS.

Note that if you attempt to crop a fragment in which either
dimension is less than eight pixels, CropGif will assume you've
made a mistake and abort.

Also note that the cropped fragment will include everything
within the bounding rectangle and the pixels under the lines of
the rectangle.


OTHER DETAILS
_____________

CropGif uses a fair bit of memory, especially for large GIF
files. It might refuse to function on machines with restricted
memory, or on computers which have a lot of resident stuff
already loaded.

If your computer has expanded memory... EMS... CropGif will
attempt to use it to store the GIF file it's working on if there
isn't enough DOS memory. Note that this is not the same as
extended... XMS... memory. A suitable EMS driver must be present
in your system for this to work.

Some of the more voluminous GIF files around might be larger than
your screen. This probably won't occur if you use a VGA card...
which will show you up to 640 by 480 pixels in monochrome mode...
but it could happen on an EGA or Herc system. In this case, you
can make the picture scroll around by simply moving the mouse
cursor to the edge of your screen.

If your computer refuses to go into graphics mode, chances are
you have a multimode card which is confusing CropGif. In this
case, you can manually force the screen mode by adding a third
command line argument. For example, this would make CropGif use
Hercules graphics.

CROPGIF ANGELA.GIF FACE.GIF /HER

The following are the mode switches which CropGif recognizes.

/CGA- CGA card
/EGA-EGA card
/VGA-VGA card in 640 by 480 monochrome mode
/HER-Hercules card in 720 by 438 monochrome mode

Some low rent Microsoft compatible mice seem to have a problem in
some graphics modes, in that their cursors will refuse to move
more than about halfway down the screen, flash on and off, vanish
and so on. The Agiler mouse, for example, is a problem. This
doesn't happen with real Microsoft mice, or with the better
compatibles, such as the LogiTech mice.

Some versions of the ATI EGA Wonder card refuse to go into the
Hercules graphics mode under CropGif. The EGA graphics mode works
fine. We're looking into this.


ROLL YOUR OWN
_____________

This is another book plug. If you're interested in writing
programs which use graphics, you'll find everything you need to
know in "The Book of Bitmapped Graphics", also by Steven William
Rimmer. It's published by TAB books, (TAB book 3558). It features
code to pack and unpack MacPaint, IMG, PCX, GIF and TIFF files,
as well as chapters on screen drivers, dithering and printing. If
you can't find it locally, you can mail or phone order it from
the bookstore listed at the top of this file.


MORAL DOGMA
___________

If you like this program and find it useful, you are requested to
support it either by buying the book mentioned at the top of this
file or by sending us $35.00. We'd rather you bought the book.
This will entitle you to telephone support, notification of
updates and other good things like that. More to the point,
though, it'll make you feel good. We've not infested the program
with excessive beg notices, crippled it or had it verbally insult
you after ten days. We trust you to support this program if
you like it.
Oh yes, should you fail to support this program and
continue to use it, a leather winged demon of the night will tear
itself, shrieking blood and fury, from the endless caverns of the
nether world, hurl itself into the darkness with a thirst for
blood on its slavering fangs and search the very threads of time
for the throbbing of your heartbeat. Just thought you'd want to
know that.
