Please take a look at the file SOL_AEO1.DOC which is an article I
did for Atari Explorer Online about how to get the most out of
Speed of Light. Check it out!
Speed of Light (here on referred to by SOL) has been tested on all
Atari computers and works on ST,MEGA,STE,TT, and Falcon computers. SOL
3.8 now runs in all resolutions of 256 colors or less, including
MONOCHROME (2 color) and medium (4 color) resolutions! It also runs
under MultiTOS, and allows switching from image to desktop in a flash.

and EZform registration letter. You will be asked whether you want
to print a filled out form to the printer or to a disk file called
REGISTER.TXT in ASCII format. A blank form is also included in the
file REGIFORM.TXT. Send an EZform (with all the information
required in the registration dialog box) and AT LEAST $25 United
States funds (see below for foreign registrations) to this address:
Stuart Denman
1751 N.E. NAOMI PL.
SEATTLE, WA 98115 <<==-- This was wrong in SPOFLT35.DOC!

Make checks or money-orders payable to Stuart Denman, or send CASH.
Please allow at MOST one month for a response (especially during the
summer) before you try to contact me again. PLEASE SEND YOUR E-MAIL
ADDRESS IF YOU HAVE ONE. If using E-mail, you will get your keycode
within one week (of when I received it), sometimes the day I receive
your letter (for cash shareware donations). I do sometimes go on

summer, thanks!
***** FOREIGN ORDERS READ BELOW *****
If you are registering from a country other than the United States,
you have two choices on how to register. You may either send your
registration money and form to me, or send it to a designated foreign
registration site.

(This is the preferred way, if you are in Europe).

Europe. He will accept UK cheques or cash, Euro-cheques, and Postal
Orders. Eventually, he may accept credit cards (you should contact
Denesh about this). The registration is 20 pounds UK.

IF REGISTERING FROM OTHER NON-U.S. COUNTRIES:
---------------------------------------------
Send your registration payment and form to me (Stuart Denman) in the
United States. Foreign orders must send AT LEAST $25 U.S. CASH or
money order, or you can send the EQUIVALENT of AT LEAST $30 U.S. MONEY
IN CASH NOTES OF YOUR FOREIGN CURRENCY. NO UNSTABLE CURRENCIES, only
things like Deutch-Marks, UK Pounds, and other stable currencies that
I can easily exchange with small fees. If you are in Europe, please
register using the prodedure above.

---===>>> RUNNING THE PROGRAM <<<===---
---===>>> AND IMAGE LOADING <<<===---
-----------------------------------------
I recommend that you use a program like Warp 9 or NVDI with SOL, as
it often can take a long time to draw the dialog boxes without these
software accelerators, especially the Options Dialog. SELECTRIC
Fileselector is now supported, so you can select multiple files if you
have it installed.
-----------------------------------
---===>>> IMAGE FORMATS <<<===---
-----------------------------------
SOL 3.8 now supports Brainstorm's DSP JPEG decoder for the Falcon030.
If you have this program installed in your AUTO folder, SOL 3.8 will
use it to quickly decode JPEG images.
----------------------------------------
---===>>> THE OPTIONS DIALOG <<<===---
----------------------------------------
B> ">>" Button - This calls up the Slideshow Settings Dialog. Here
you can move the slider bar to select the number of seconds to
display each image. When the direction is selected (forward,
backward, etc) SOL will automatically switch between images,
displaying each one for the specified number of seconds. The way it
switches between images is determined by the second popup menu.
"First" and "Last" allow you to select the first and last image for
display. Only images between and including these images will be
displayed. If the first image comes after the last image, the two
image numbers will be exchanged. If you display an image outside of
this range of images while in the middle of a slideshow, the
slideshow will terminate until you enter the range again. The
display time is calculated from the point where the image finishes
drawing. The Record Script button is described in the file SCRIPTS.DOC.
-------------------------------
---===>>> DITHERING <<<===---
-------------------------------
There are three dithering patterns built into SOL (ordered 1+2 and
random dithering). Others can be loaded into two empty slots. These
dithering patterns are the same as the ones used by GEMview and have a
.DIT extension. To load one of these, click on the Load button from
the Dither Settings Dialog, choose slot 1 or 2 from the alert box, and
select the .DIT file with the fileselector. Some dither patterns are
included in the folder DITHER.
Click on "Set" next to DITHER PATTERN in the Options Dialog to enter
the Dithering Settings. Here you can see what the different dither
patterns look like, and set other things. There are two "folder-tabs"
that control dithering patterns for normal and FIS (filter) dithering.
Filter dithering does not have contrast or step slider bars.
When you have the "normal" tab selected, the two sliders control
the number of dither steps and the dithering contrast. Slide the
dither steps bar to see the effect that it may have on your image.
The dithering contrast sets the maximum contrast that two dithered
colors can have between them. This is so that you do not get a lot
of bright specks in your image. Play with these settings to see the
results. These two slider bars have no effect on when FIS is used.
---------------------------------
---===>>> PREFERENCES <<<===---
---------------------------------
The preferences dialog can be selected from the Options Dialog by
clicking on the "three-bars" button in the upper right corner of the
dialog. The following options are available:
*** Preferences under the "Settings" tab: ***
>> Blank screen while drawing image. This displays a blank screen while
an image is being drawn to the screen. When the image is done
drawing, the image appears instantly. This is used mostly for
slideshows.
*** Preferences under the "Truecolor" tab: ***
>> No Dithering/Standard/Error-Diffusion. This selects the type of
dithering and turns dithering off and on for truecolor conversions
while loading in JPEG images. Error-Diffusion dithering is not
supported as of this version. No dithering is the same as random
dithering only when using "Fixed Palette" conversions. No dithering
is much faster when using "2-pass Octree" conversion, but does not
produce as nice results.
>> Truecolor Dithering. This popup selects the current dither pattern
used for "2-pass Octree" and "Fixed Palette" conversions. Loading a
dither pattern can be done from within the Dither Settings Dialog, and
can then be accessed from the Preferences Dialog for use in truecolor
conversions. Previous version of SOL used only random dithering for
fixed palette conversion, but standard dither patterns can now be used
for better (or just different) results.

---===>>> FINAL COMMENTS <<<===---
------------------------------------
Speed of Light version 3.8 represents over three years of very hard
work. I would like to thank Dan Aylward for his help in testing. I
would also like to thank all of those who registered for version 2.x
and version 3.x early on! If you have not registered yet, please do!
Your support helps me bring more quality software to the Atari
platform. Since Atari computers are a dieing breed (*sniff*),
Shareware is the only reliable source of good software, so if you see
something you like, SUPPORT IT BEFORE IT IS TOO LATE!!!
