Contained in this package are six GIF utilities
They are:
GDIR : Program to display info about all GIF files in a directory or of
the GIF files specified on the command line such as size, number of
colors used, and presence of a global color map
CHK4GLTE : Program that checks all GIF files in the current directory on the
presence of the GIFLITE header
STRIPHDR : Program that strips the GIFLITE header of all specified files
(This is only possible with the REGISTERED version of GIFLITE, so
that's no reason to register anymore)
GIFPALET : Program that shows all colors that are used in the specified GIF
file on screen
GIFBGRND : Program that sets the background color of a GIF file. GIFPALET can
be used to pick the appropriate color
GIFSIZE : Program that changes the size of a GIF file to the nearest standard
size, not changing the image in the GIF file but putting it in the
middle of the screen (e.g. a 325 x 416 GIF file will be sized to
640 x 480 and the image will be in the middle of the screen)
It is also possible to size a GIF file to a user specified size
To find out how to use each program just type in the program name without
any parameters. This will tell you how to use each of them.
This doesn't work for GDIR and CHK4GLTE however.
CHK4GLTE does not take any arguments but lists for all GIF files in the
current directory whether the GIFLITE header is present or not.
GDIR takes about the same parameters as the DIR command does (no /p or /w or
that kind of stuff however).
Examples : GDIR
GDIR paulina.gif (note: GIF extension should be specified,
otherwise paulina is assumed to be a directory)
GDIR d:\gifdir\ (note: do not specify *.* or *.gif, the GIF
extension is already assumed)
Questions about the programs:
Q) Why would I wanna strip the GIFLITE header?
A) Some programs, like DTP256 or earlier versions of GDS, do not know how to
handle GIF files with a GIFLITE header. Strip them off and everything
works fine.
Q) Why would I wanna size a GIF file to a standard size?
A) I had the need for this when I was using GDS (Graphic Display System, program
to view GIF, PCX (and more), and to make index files (the accompanying GIF
file was made with this), great program by the way). It stretches a GIF file
to fit in the window. This led to the result as shown in the first picture
of each row in the accompanying GIF file. GIFSIZE the files and the result
is as shown in the second picture of each row. Picture number 9 was sized
to 1024 x 768 just by specifying
GIFSIZE oct90_3 1024 768
on the command line (by specifying "GIFSIZE oct90_3" the size would have
become 800 x 600 (nearest standard size))
Q) Why would I wanna change the background color of a GIF file?
A) Because it looks better. Look at the third picture of each row in the
accompanying GIF file. To choose a nice background color, GIFPALET can be
used.
And here's for the good news: ALL UTILITIES ARE FREE.
Nowadays, almost every nutcase who wrote 3 lines of code thinks he can ask $20
or so for his program, but I wrote them for myself in the first place and if
anyone else can use some or all of them he/she is free to do so. Use whatever
you need and pass it on to anyone you know (provided you give him or her the
whole package as distributed by me)
