This is some notes on changes between versions. Like all others
I find it very painful to update documentation. You will now
have a small document for NakedEye 1.10 in three formats: TEXT,
POSTSCRIPT, WINWORD 2.0. The files are nakedeye.txt, nakedeye.ps
and nakedeye.doc respectively.
Please refer to nakedeye.cfg, nakedeye.snd and nakedeye.trc for
fine tuning the way NakedEye 1.10 works.
Enjoy!
Changes from 1.02 to 1.10
---------------------------
NakedEye 1.10 migrates into the world of Object-Oriented
programming. It has been modified gradually to take advantage
of object-oriented approach to control the code size and add
some more functionality without getting the program too big.
However it is expected that an Object-oriented program is
a bit bigger than normal.
* PostScript generation for PostScript laser printer.
NakedEye offers to ways. The first way is to generate a
single postscript file for the current image. The user
will be asked to supply the output file name and the
mode Vertical, Horizontal or Automatic. The second way
is to generate postscript files for all loaded images.
The ones which have not been decoded will be skipped.
In this mode the user chooses the orientation of
the page for all images, and a compression option is
available. If compression is chosen then every output
file is compressed into a ZIP archive. This will reduce
the amount of disk space needed by a factor of 3
about times or more. In a test I generated 41 images
of size 640x480 and bigger in 45 minutes. This took
up 8Mbytes of disk space, and more than half of the
time was spent in compression. If compression was
not used then the diskspace needed would be close to
30Mbytes. TO set up for compression one must edit
the file nakedeye.cfg and add the name of the file
compressing program. The default is zip.exe that is
copyrighted C) 1990,1991 Mark Adler, Richard B. Wales,
and Jean-loup Gailly. This has to be installed on
your computer system. If it is not NakedEye will
know and does not prompt for this option.
The default compression format is ZIP. Every PostScript
output file is in a ZIP archive of its own. The program
UNZIP is used to decompress them. PKUNZIP can also be
used to uncompress them.
At the middle of processing NakedEye cannot be interrupted,
however any key will stop NakedEye when it finishes a
postscript file. The user is then asked to continue or
stop.
* A mouse click in the image area will now activate a pop
up menu. This menu allows popular commands to be selected
even when the control panel is not available in FullScreen
mode. It makes it significantly faster to activate a
command. This is probably the most significant enhancement
from NakedEye 1.02
* The arrows functions on the control panel have been
removed. They were accessible by the arrow keys on the
keyboard therefore wasting space on the control panel.
- Function VertFlip now looks if there is just enough
conventional memory to do a flip rather than using file
swapping. This makes it several times faster to flip an
image of size about 640x480.
- Minor changes to the presentation of images when a
slide show is on. Especially when the fullscreen mode
is chosen for the slide show, when ESC is used to get
back, NakedEye switches automatically to Control mode
to give access to the Control panel.
* A new function is added to support association between
text files and GIF files. You can display you favorite
poem at any place on the screen when you look at a
picture. When a slide show is on, the key T is used to
activate this feature. Other time, the function is
activated by mouse from the Control Panel.
This works the same way as the sound association file.
The exception is that there are two optional numbers
after the text file name. They tell where the window for
the text should be. The configuration file is
nakedeye.trc . To change the default extension look
at the variable textext in nakedeye.cfg
* The Control Panel can be flipped to the left or right.
Flag lefthand can be set to yes in the file nakedeye.cfg
to make this a default. The key F4 is employed to toggle
the mode on/off.
- When Glass is running, a click of the mouse stops it.
Similarly for Convex and Concave, but it only stops the
building of the mirror and let you choose a new area for
a new mirror.
- Significant faster refresh after prompting user for some
keyboard input.
Changes from 1.01 to 1.02
-------------------------
There have been little changes. In fact this is 1.01 released
again with the little bugs fixed up. I am preparing version
1.1 with a lot of changes. It still has some bugs to be fixed.
- Some known bugs have been fixed up.
- There is no more restriction on this software. There is
a key comming with the distribution to allow acess to all
functions. The software will not expire any more for this
version. Versions comming after this still expire.
- The Sound association file is NakedEye.snd . It is the
default association file for GIF and VOC files. If you
have a soundblaster card, simply edit this file to set
up the association and play the sound. The key M is used
to activate the sound when you are having a slide show.
- The TEXT association file is NakedEye.trc . It allows you
to set the association between GIF and TEXT files. The
text file can be displayed by selecting ShowText on the
control panel or T when a slide show is on. This is for
people who want to display some comments or poetry etc.
* Version 1.1 will be released later in the year when I get
the bugs out. It will be very different with pop-up menu
user interface. It will also support XMS memory. I will
also rewrite the documentation to make it simple and precise.
Changes from 1.0 to 1.0.1
-------------------------
There are several changes. I am not rewriting the manual
because it simply take too much time to be worth it. From now
on all new changes will be in this NOTE.TXT file.
There have been changes from version 1.0 to version 1.0.1
Most features are the same but the internal implementations
may have changed for better or for worse. You will find
the version number changes very slowly because the software
is fairly complete in what it is designed to be: a GIF Viewer
Here are the changes from 1.0 to 1.0.1 (Oct 1991). A * means
important.
* The executable is now abbreviated to ne.exe . Many
people have found NakedEye is too long to type.
- NakedEye will swap itself to EMS or XMS memory if DOS
escape is invoked by F9 or SHELL. If it cannot find
either types of memory it will spawn the DOS shell
without swapping itself out of conventional memory.
* NakedEye is now an overlay program. It will have only
active segments in conventional memory. The rest is in
a memory cache in EMS or XMS. This has released about
60K extra out for general use. Typically after start-up
there will be 370K of memory left for general use. You
should set up your system with some EMS memory if you
have 2Mbytes or more of memory. A line like the
following (or similar) can be added to your config.sys
device=c:\dos\emm386.exe 1024 ram
If you have a lot of memory then the more memory is set
up for EMS the faster NakedEye will refresh display and
paint the next picture. I prefer to reboot my machine
with a different set up when I want to use NakedEye
with a lot of GIF files. There are many programs on the net
for this purpose.
It is recommended that NakedEye is installed on your hard
disk. Running NakedEye from a floppy disk is too slow.
- Rotation and Resize are now faster if there is enough
memory. NakedEye will swap itself out of conventional
memory and invoke a tiny program outside to do the job.
If there is about 500K left when NakedEye starts, it
will be able to deal with images of size 800x600 or
similar sizes very effectively.
* A small change to user interface. Option /m alone will
put it into a selection menu which was the default in
version 1.0. It is nicer to start NakedEye into the
first picture for experienced users.
- NakedEye will now deal with about 97Mbytes of information
after decompression from GIF into normal indexed raster
image. About 200 GIF files can be opened in a session
if they are not all too big.
* Command Shake'it and ShLevel are added for the pleasure
of the eyes. The Shake'it command add vibration to a
selected region. The other tells NakedEye how much to
shake the region. Use the mouse to pause for selecting
more regions to be set into motion. Type ESC will get you
back to normal control.
* Command Curtain and Curmode are added. Curtain draws a
curtain of 50% visibility across the area selected. Curmode
controls the direction of drawing. This set is another
chewing gum for the eyes. These weird commands and the
lenses etc ... are the unique features of NakedEye.
* A sound player is incorporated in the distribution. It is
called SPLAYER.EXE . This program will play a VOC format
file for the Sound Blaster card continuously. Two commands
are added into NakedEye 1.0.1 called Music and Mfile.
Music plays the sound file associating with a gif file.
Mfile let you name the associating file for GIF and VOC
files. You need a Sound Blaster board to play music/sound
while looking at the GIF files. This SPLAYER.EXE program
takes an optional argument -ns standing for non-stop playing.
The format of the sound association file is simple. A line
starting with # is a comment line. The rest contain two
formats; one for the sound player and the other for GIF and
VOC files
Example: File NakedEye.SND
######################################################################
# This is the sample sound association file. #
# The character # is used to comment a line. #
# #
# player should be set to your favourite VOC player. The default one #
# is SPLAYER.EXE distributed with NakedEye 1.0.1 . There can be more #
# than one player. The last one immediate before the correct #
# GIF = VOC association entry will be used to play the VOC file. #
# #
######################################################################
player=.\splayer.exe
paradise.gif=.\oxygen.voc
wgardn1.gif=.\waltz1.voc
The above file shows an example of the sound association file
between GIF files and VOC files for NakedEye 1.0.1. You can see
that the sound player is .\splayer.exe and for every GIF file
there is a VOC file name. Also note that the file name on the
right hand side of = is with full directory path name.
The name on the left is the filename of the GIF file without
the directory path.
Now you can set up the association file between GIF and VOC
and play music or sound when you view the picture. BE CAREFUL
and make sure that FULL PATH NAMES are used for the sound
player and the VOC files. If this is not set correctly NakedEye
will simply complain "Cannot open". You will have to edit
your own association file or modify the sample file NakedEye.SND
to make sure that it works even when you run NakedEye from a
directory different from where you install NakedEye.
The key M was used for displaying the memory status in 1.0
Now it is used to play sound (Music). When you first request
for music, NakedEye will ask for the association file name. It
will scan the file for GIF <-> VOC association and play the
VOC file. Subsequent request will cause NakedEye to scan the
same association file. You can change the association file any
time by the command Mfile which must be selected from the
control panel.
* Slide show with MUSIC is possible now with NakedEye 1.0.1
You simply type M when the slide show is on (using F2).
NakedEye will play the VOC file associating with the current
GIF file, when finished it will display the next GIF file and
play the next sound file and so on ...
When the slide show and music are on at the same time, to stop
them you have to type ESC twice.
