- GIF FILE CROPPER 1.1
- __________________________________________________________________
-
- If you like this program, please do one of the following:
-
- Go down to your local bookstore and buy a copy of "Coven: A
- Novel", by Steven William Rimmer, published by Ballantine Books.
- In Canada, try Coles... they usually have it. Read the book and
- tell your friends about it if you like it. Send us some comments
- about the book or a photocopy of the cover and we'll consider you
- a registered user of this program.
-
- Alternately, send us $25.00, the normal user fee for this
- software. (The book is $3.95 or $5.50 in Canada: considerably
- cheaper than cash.)
-
- Registered users of this software are entitled to phone support,
- notification of upgrades and good karma. Our address can be found
- at the end of this file.

-
- 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.
-
- 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
- doesnt 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) and should
- be available in August 1990. It features code to pack and unpack
- MacPaint, IMG, PCX, GIF and TIFF files, as well as chapters on
- screen drivers, dithering and printing.

- 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 $25.00. 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.
