Introduction
JPG2GIF and GIF2JPG are a set of shareware programs which convert GIF
images to JPEG images and JPEG images back to GIF images.
Why would you want to do this? Typically JPEG files are several times
smaller than GIF files. So by converting images from GIF to JPEG you
save on modeming time, long distance charges, and reduce disk storage
requirements. The disadvantage is that you can't view JPEG files
directly, you have to convert them back to GIF files so that you can
use your favourite GIF viewer.
How to Use GIF2JPG & JPG2GIF
To convert .GIF files to .JPG files:
GIF2JPG [options] [files...]
If any .JPG files with the same name already exist, or if the program
encounters any GIF89A files, you will be asked whether or not to
proceed.
To convert .JPG files to .GIF files:
JPG2GIF [options] [files...]
If any .GIF files already exist you will be asked whether or not to
overwrite them.
Each program has two options:
-a: automatically proceeds (overwriting any existing files and
converting GIF89A files).
-k: kill (removes) the original files after they are processed.
Examples:
GIF2JPG *.gif
Will convert all .gif files in the current directory to .jpg files.
JPG2GIF -k test.jpg madonna.jpg n?.jpg
Will convert the specified files back to .gif files, deleting the .jpg
files.
Hardware Requirements
An IBM PC or clone (at least a 80286 for any kind of performance).
A hard drive (JPG2GIF needs to open temporary files while processing,
you must have at least 3 times as much disk space available as the
largest image you are converting (for example, a 640 by 480 file
requires 1 Megabyte of free space].
MS-DOS or PC-DOS 3.1 or later.
380K of available RAM.
