DEGADISP.DOC
A Lightning Fast D.E.G.A.S. Picture Viewing Program
View Any Resolution Picture on Any Monitor
Oh, no! Not another D.E.G.A.S. picture converter? Well yes, but
this program is different. I got tired of always having to
switch to a monochrome monitor to view high res D.E.G.A.S.
pictures, and having to change resolutions to view pictures on my
color monitor. The existing conversion programs are so slow
(particularly in the low res color to monochrome conversion) that
you cannot just select a picture and view it. Instead you must
convert the picture to a new format and waste disk space with
several different versions of the same picture.
DEGADISP.PRG is written entirely in 68000 assembly language with
the picture conversion routines tweeked for the fastest
performance possible. The result is that a low res to high res
conversion takes about a second (D.E.G.A.S. Elite takes 75
seconds to do the same conversion). This allows you to start up
the program on either a monochrome or color monitor and view any
D.E.G.A.S. picture file in any resolution. DEGADISP will display
picture files from both the original D.E.G.A.S. program and from
D.E.G.A.S. Elite (in the uncompressed format only). In addition
it will display Neochrome picture files on any monitor if you
rename the .NEO picture to .PIN
To run DEGADISP.PRG, double click on the program icon from the
desktop. The program will display a copyright message and allow
you to continue (press "Return" or click on "Lets do it") or get
a short description of the program ("Tell me more").
DEGADISP.PRG then opens a file selector box of all .PI1, .PI2,
and .PI3 files in the current directory on the current drive.
Just select a file to view and click on "OK" to see the picture.
Pressing any key or clicking the left mouse button while the
picture is being displayed will return you to the file selector
box. Click on "Cancel" to return to the desktop or select
another file to view.
To view picture files on another disk or directory, click on the
line under the word "Directory:" at the top of the file selector
box. Press "Esc" to clear the default path and type in a new
drive such as "B:\*.PI?" This will select all D.E.G.A.S.
pictures on drive B. Then click the mouse pointer inside the box
showing the list of picture files to read the directory of files
off of the newly selected disk.
To view Neochrome pictures with DEGADISP, you can rename the .NEO
Neochrome picture name to .PIN at the desktop using the "Show
Info..." selection of the File menu. Another way of displaying
Neochrome pictures from within DEGADISP is to select a new disk
or path such as "A:\*.NEO" as described above. This will allow
you to select all Neochrome picture files on drive A.
DEGADISP.PRG is an experiment to see if there is a market for
Shareware on the Atari 520 and 1040 ST. Shareware allows you to
try out a program to see if it is useful to you without having to
purchase the program first. If you like DEGADISP.PRG and find it
useful, a donation ($15 suggested) to the author (that's me, see
below) not only would be appreciated but would inspire me to add
enhancements to the existing program. For example, I would like
to add support for D.E.G.A.S. Elite compressed files to the next
version of DEGADISP.PRG as well as support for the color
animation included in some Neochrome and D.E.G.A.S. Elite files.
Ultimately, I would like this program to provide a complete
slideshow for Atari pictures with programable display time and
user control of picture display order.
Well thats it folks. If you like the program, contributions will
be graciously accepted (and you will get the next version of the
program delivered directly to you). If you have suggestions for
this program or other programs you would like to see written for
the Atari, please write to me at the address below or leave me a
message on Compuserv [ID 73157,2364].
