Welcome to GIF Descriptor V1.0(3/29/91)
by Rollin White
INTRODUCTION
GIF Descriptor is a pair of utilities that reads and writes
descriptions of your .GIF files. Adding descriptions using
GIFWRITE does not interfere with the image itself and completely
complies with the Compuserve GIF 89a and 87a specification.
These utilities are useful under many circumstances. First,
when uploading a file, no longer to you have to shell to your
viewer and bring up the GIF to remember exactly what the GIF is,
the description is more easily available. Second when searching
through your collection, it is much easier to find that picture
you are looking for when you have descriptions to read instead
of just filenames. This is especially helpful if you have 100's
or 1000's of GIFs(like D.D.). Let's face it 8 characters is not
a lot of space to describe a picture.
HOW TO USE THE GIF DESCRIPTOR UTILITIES
There are two programs that make up the GIF Descriptor
utilities GW and GD which stand for GIFWRITE and GIF DIR
respectively. The process begins by running GW which adds the
actual comments to the file. Then GD allows you to have
directory of your GIFs including their comments. A detailed
description of each utility follows.
GW(GIFWRITE)
To start GW use the following command line syntax:
GW <d:\path\filespec>
Where d is stands for any valid drive, path is any valid
path, and filespec is either a valid file or a valid set of
wildcards. An example is:
GW e:\gifs\*.*
Drive letter and path are optional, but you must include a
filespec whether it involves wildcards or is and exact file
name.
Once GW finds a file it takes one of two courses of action.
If the file is not a GIF file it lists the name and tells you
that it is not a GIF file. This might be the scenario if you
were to use the "*.*" filespec.
If the file is a valid GIF file, GW informs you of the file
name and its current description. If the file has no
description or if GW has not been run on the file before GW will
provide a description of "No description given". You will then
be prompted to enter your new description of thirty characters
or less. You also have the option of pressing enter which leave
the current description unchanged. An example is given below:
The current description for CAT85.GIF is:No description given
Enter your new description or press Enter for no change.
<-30 limit of 30 characters or less
As you can see everything is pretty straight forward. This
process will continue for every file that qualifies under
filespec.
GD(GIF DIR)
GD provides a directory of files including name, size,
dimensions, and description. The command line syntax for GD is:
GD <d:\path\filespec>
Where d represents drive letter, path represents any valid path,
and filespec represents and valid DOS filespec. If no
parameters are given, GD will use the current directory. If the
number of files requires more space than is available on the
screen, GD will pause with a "--more--" prompt waiting for any
key to be pressed.
REGISTRATION
Well if you've read this far you must be interested in the
program. I originally intended for all of my programs to be
free or to collect money for charity, but things have changed
since I came up with that idea. Recently the Governor of
California decided that the UC system would have to take a 20%
increase in students' fees would be necessary to help balance
the state's budget. Even worse, the UC Regents, the body of
wealthy businessmen who are responsible for running the UC
system decided that a 40% increase in student's fees would be
needed to balance their budget. As a result my financial
situation is looking grim. As a result I have decided that a
$10 registration fee would be in order. This money will be for
the sole purpose of paying my tuition. The benefits of
registering include free upgrades for one year. If you decide
to register, please fill out the form in the file REGISTER.TXT
and mail it to the address below.
COMMENTS
All comments and criticisms are appreciated. What can I do
to make this better? Do you have ideas for other programs? I
WANT TO KNOW! I can be reached my mail at the address below or
at the KANDY SHACK BBS at (714)-636-2667.
