COMP-U-SERVE ~ GENIE ~ DELPHI ~ THE SOURCE

From the Editor's Desk,
Having had the time to ponder the course of current events I find
many reasons to rejoice in the changes coming about in the Atari Corp.
and it's methods of dealing with the US Userbase.....In fact, I HOPE that
they will soon have the Federated, or whatever name they care to use,
stores all over the country and eliminate the goniffs they have now for
dealers.
Granted, not all the dealers are bad guys but, at this point in time
with all the doomsayers in full bloom the average "I got my life savings
tied up here" dealers are going to react unfavorably and thus "score" for
every buck they can. This type of situation warrants Atari to get the
national chain into full swing ASAP. To the doomsayers I say...you folks
are pure bad news unto yourselves and are doing more harm to the Atari
Userbase than any good you can possibly imagine. The time is at hand to
stand by the machine and company we have embraced, changes are being made.
We were extremely vocal in gaining the attention of Atari and we
did so. Now, with Atari being responsive to our input, we stand ready to
accept the changes we have clamored for. We dont expect total alignment
with the userbase suggestions. We do however, expect some similarities.
After all, we ARE the ones paying the bills (collectively) and should be
heard and responded to..and we have been. Atari is on a course of
corrective measures that can only lead to true and lasting success.
Having heard that certain members of the Harris types of online folks
from Atari had a "mini" conference a day or so ago with one of the
doomsayers amazed me. It would seem rather foolish to add fuel to the
fires of those that say, "THE ST IS DEAD" ! To insinuate that Atari will
have little or NOTHING to show at Comdex is truly a hypocrisy of the word
loyalty to one's employer! In addition, it is just plain vile to
perpetrate such acts while ONLINE representing ATARI!! That particular
department needs further adjustments.
Long Live Atari,
Rex.....

THE SKY IS FALLING!
===================
*******
NOTE:
-----
This is Dave Small's response to the announcement by Neil Harris
that he has resigned from Atari. For those who don't know Dave he is the
developer of the Magic Sac and Spectre 128: devices that emulate the
Macintosh computer on the Atari ST.
*******
This is really stunning.
If you think this is just another "Atari employee splits" note, consider:
1) Neil was the spearhead of Atari online. Here, Genie, Usenet, Delphi,
you would find Neil. The support other than Neil has been fragmented to be
charitable. (Due credit goes to Julius, though). Given the power of the
online networks for marketing, and Atari's upper management completely
missing that, this is big trouble.
2) Unless I am much mistaken, I'll guess Neil had Atari stock options.
What does it tell you that he's leaving? I don't know how Atari stock
could drop more (it's down to 6), but there's always a way. Maybe they can
"unsplit" stock to get it back to 12, *grin*. This means Atari is in big
trouble.
3) Neil is the *only* effective public speaker Atari had. Atari did
manage to waste much of it by forcing him to go say things that weren't
so, or were only a little bit true. Neil gave innumerable talks and
presentations to user groups at shows across the country. Just who is
going to replace him? You don't find people like that easily, or
sometimes, at all -- look at the number of corporations who have *no one*
like that. This means Atari is in big trouble.
4) This happened right before the "big" CO here online with Sam. Big
trouble.
5) This happened right before Comdex. Big, big, big trouble. Neil was one
of the few people in an autocratic, 1950's-style management office that
had any feel at all for reality. Now, what are we going to get? A
repackaged ST game machine with a laser tag pistol? A VCS / ST? You can
bet that when it appears (if) at Comdex, there will be ghostly vapor
surrounding it, the signal of a product not to appear for another year.
Big, big trouble.
6) Atari has no grasp of the current US marketing situation; you can't
stop support the instant the customer walks out the door with their ST and
you cash their check. Atari tries to do that, of course. I remember well
Alex Leavens getting canned for daring to support people who hadn't bought
the developer's kit (among other peccadillios). "Business is war", when
the people you are warring on are your *customers*, is dumb. We are in a
service economy now; people expect *service*.
No? Atari top management held up release of the auto hard disk booter
for a LONG time, claiming it would "cause a lot of tech support calls".
The author, one Landon Dyer, is now at Apple, disgusted with Atari. He
*wrote* most of the ST's BIOS; losing a lore-master like that is always
very painful for a company.
7) Neil Harris has been with Jack T. a *long* time. What does it tell you
that he's bailing out now? Do you think he would if he saw any hope of
things changing? Do you think he'd go through the shock of job loss,
moving, new company, etc, if he saw any chance at all? *Neil is not
stupid*. Atari made him say stupid things, and folks like ST-Report
interpret that to mean Neil is stupid. Wrongo.
8) John Skruch -- whose word I trusted, a rarity at Atari -- is gone.
Sandi Austin, who did those user group shows (remember?) is gone. Richard
Frick, who was *instrumental* in getting the Magic Sac going, only to
watch Atari's top management cold-shoulder it (Quote: "Why would anyone
want to run Mac software when they have TOS?"), is gone. They've all left
Atari recently.
9) Just who is going to get Atari publicity from folks like Jerry
Pournelle anymore? Neil sold a lot of Ataris that way, and made the
Tramiel people a lot of money.
10) Is it possible that Neil feels he's getting out before his reputation
is ruined by an Atari crash? Already it's been damaged by things he had to
say (Atari corporate policy).
11) The Comdex timing is especially significant. If Neil saw a future at
Atari, it would be new products announced at Comdex. I have heard from
other sources that Atari's top level management is now backing off from
introducing ANYTHING new or interesting at Comdex -- wouldn't want to
distract people from the ST, folks. Quote: "Atari's domestic market is
Europe. The US is Atari's international market". Unquote. This makes
Comdex look like a splash to me -- much like the May one, in the
Abandoned Booth.
12) It says a LOT to me about working conditions at Atari that even
Neil,
who is pretty tough and good at political infighting, is leaving. If
you've never seen a 1950's style autocracy, well, check it out. It is hard
to stand (look at the number of people Atari has gone through at top
management), clearly. Other companies don't tax their personnel like this;
they realize that this is not the 1950's anymore, people are scarce and
hard to find, and need to be *part of the company*, not just some
slave-employee. Many other reports of working conditions at Atari make it
sound like hell to work at.
13) If Neil doesn't think there's going to be profit in his stock
options, you ought to be thinking about it too. (Again, this is a guess).
It is possible that Atari is folding up; the collapse will just take
awhile to reach the public.
14) Most ST developers are seriously considering jumping ship; a lot
already have. Even Tom Hudson, arguably the best, is gone. Given how
little Atari supports its developers (something Neil fought for) and
gives online support (ditto), and that it could care less about selling
into the US, it seems a waste of time to develop for the ST for the US
market, when there's markets like Amiga, IBM, and Mac to develop for --
who have good documentation, people who aren't propeller-hat-heads
online, and so on.
15) I think this marks the end of Atari US. The Spectre 128 is almost
certainly my last ST product.

Fm: Neil 70007,1135
To: David and Sandy Small 76606,666 (X)
I refuse to allow my departure to be used as evidence for such a gloomy
scenario for Atari, even by someone I like as much as you, Dave.
Yes, I passed on some stock. But not nearly enough to qualify me for
the "golden handcuffs" club that binds some of the vp level and above.
To address a couple of minor points, John Skruch is most certainly not
gone. He seems to be doing very well -- with the success of Atari video
games, members of that division are being treated decently.
And as for Alex Leavens -- it was *my* call, period. He spent a fair
amount of time online, which was good. But he did not spend enough time
on the rest of his job with the tech support group, and that was why I
brought him in. It was painful to have to let him go, but that's the
price you pay when you're in management.
Yes, I share some of the concerns you expressed. Mainly I am concerned
for my coworkers at Atari who are underappreciated and underutilized.
There is also some concern over product directions, but it ain't over
until it's over, and that isn't quite yet.
Finally, for the record, I take with me a fair amount of Atari stock,
which I have no immediate plans to sell.

THE BEAT GOES ON
================
by T."Rex" Reade
AN APOLOGY FROM REX!
Having been given a line of seemingly credible information from a
very credible source within Atari, I now apologize to all concerned for
the information contained in the ST Report 54 article "The Beat Goes On".
There absolutely WILL be multi-tasking in the 68030 series of ST machines.
I doubt I will receive any further erroneous info from this person as they
are no longer with Atari.
It is very difficult to disagree with a people you know and respect,
but..
To credit ST Report with having caused the demise of certain Atari
employees is wild. Actually, to those who would say these things, we say
thanks ....but NO THANKS for such flattery.
We are flattered to see that one of the so-called leaders of the
Atari community feels we wield such power. I find it equally amazing to
see this particular item attempt to portray the idea that it is composed
of FACTS... it is NOT!...frankly speaking, this item by Dave Small is ...
HIS OPINION and HIS OPINION ONLY!
We all know the joke about opinions.....right? , <<<Big Grin>>>
All the crepe hanging going on is about to turn my stomach! Atari
is NOT going anywhere but on the sales and service improvement path. To
pointedly say, (as if armed with facts and figures), that the days of
Atari are "numbered" is a slanderous misrepresentation. A "better" way of
expressing this is..the days are "numbered" for certain detrimental
individuals in Atari's Employ.
To the respected members of the Atari Community I plead with you..
"TAKE DOWN THE PURPLE AND BLACK FLAGS there is no death of anything that
we must take notice of. Besides, there really are those of us who wish to
continue to support Atari and it's future. We may be critical towards
Atari at times but let me tell you this; We will support Atari until such
time that either they or us are no longer a viable enterprise.
Speaking of Atari needing to get the rest of it's "outspoken"
employees in line.....how about Mike Dendo, the new Vice President in
charge of Computer Sales, going to Michigan, telling the good folks there
that Atari had three soft quarters this year and that they needed the
fourth to be a huge success to "bail out"!!??? What is this guy? He
certainly is NOT an accomplished salesman let alone a VICE PRESIDENT!
Maybe he works for the other competition! This bird needs to hit the
revolving door! Also, the online folks need to concern themselves ONLY
with what they are there for, (representing Atari) stay out of politics,
personalities and endorsements of "other" related products for the ST
that are not manufactured by Atari. There is NO need to resurrect certain
practices Neil took with him.
In addition;
ALEX LEAVENS...was encouraged to leave because of his spending too
much time "online" and not enough time at his assigned duties.
John Skrutch has NEVER left Atari, in fact, his division is having a
very good year.......
Furthermore, anyone who attended the SPRING COMDEX will recall the
fact that Neil Harris, *** ex-ATARI SPOKESMAN *** spent the best part of
the time there online playing Games!!!! AND....when he was away from the
cpu, he left FLASH booted and the system online (he has a system wide free
flag) so no other person would attempt to use the computer. I saw this as
did a host of others. In my humble opinion, the handwriting was already
on the wall.....Neil didn't really care anymore at that time and his
departure from Atari would soon be forthcoming. I am NOT putting Neil
down, I AM saying he did the right thing in making a career change before
his depressed attitude caused him severe personal problems.
In conclusion, because of the recent shakeups at Atari, I am lead to
believe that the bosses and most of all, Sam Tramiel, are bent on making
the U.S. Marketplace Atari's best success story. If such is not the case,
then it would be wise to say ...."they had better go underground" because
a lot of "not so wealthy" people tied up some "big" bucks in the Atari
Dream........Personally, I feel all is well in Sunnyvale, and we still
haven't seen the end of the major changes in staff or in policy. Besides,
Mega 4s and Laser printers make terrible hats!

HARD DISK FACTS AND FIGURES
===========================
The Straight Info!
------------------
To begin, 99% of all hard disks are made to conform to IBM standards. With
this thought in mind we shall proceed.........
The most readily available and in my opinion, the most reliable hard disk
is from Seagate......next in line is the Miniscribe. There are
others but you must make sure they conform to the IBM standard.
IBM STANDARD: ST-506/ST-412
---------------------------
Most commonly found hard drives do not have controllers built in. These
are the most reliable and economical drives to use.
WHAT IS THE CONTROLLER???
=========================
This goodie is the custodian of your hard disk! It directs all I/O
functions to the hard disk and it points to and accesses each cylinder.
It "controls" everything.

Be Advised, as of 01/01/88, Seagate began using the new I'ntl light code,
the front light on the drive is GREEN ONLY if it is made after Jan.01 1988.
If you purchase one and the light on the front is red, it's either old
inventory, used or rebuilt. I do not advise the use of the "N" type H/D,
they're limited in their flexibility of use by the embedded controller and
are more expensive. Seagate may cost more, but they are the workhorses of
the industry. The Seagate Hard Disk is extremely RELIABLE. Seagate units
40mb, and above, have auto-park.
All of the above are:FCC,TUV/UL/CSA [CERTIFIED]
The list of other types of drives is large, some are, Disctron, Lapine,
Microscience, Micro-memories, Miniscribe, Priam, Rodime, Shugart, Tandon
and Tulin. The formatted size of these range anywhere from 5-???Mb.
I purposely avoided Brand Names of packaged drives because in most
cases they use Adaptek and Seagate or Miniscribe...I have found that
Atari and Supra have gone to the 3.5 hard disk. I will cover those next
time. As far as Atari is concerned, they would have saved a fortune in
R&D if they had used the standard assembly, as the method they used is so
typical of Atari, "they walked all 'round the barn to walk in the front
door", why did they have to change the 'prom, it made the SH204 a problem
maker, why the dip switches?,,do they really think the Atari user cant
handle Terminal resistor packs and jumpers??? Bad Move! Some of the
companies have gone to Miniscribe, (the coffee grinder) to cut production
costs, they will go back to SEAGATE as soon as they realize the RMA
numbers are eating their lunch!
Remember that all these drives (except for a few) come without a
controller, you really want it without a controller..it's less expensive
and works out much better for you in the long run.....you will see!
The actual chain of connection for a hard drive is:
1-hard disk
2-controller
3-interface..and the DMA port.
MFM- This is a format style most commonly found in use although recently,
RLL has been becoming far more popular as it is a condensed compact
format thus allowing more data to be stored on an equivalent size hard
disk. The major difference is the media itself in the hard disk is
PLATED to insure accuracy and longevity. Think of it like plain
recording tape and Cr02 Chromium Dioxide tape. The recording media in
the "R" drives (Seagate) is of a high quality and plated.
In most cases, the Interface, ( Host Adapter ) determines what type of
system the hard disk will comply with. It also (usually) has a clock/
calendar built in.
In reality you can take a hard drive system made for an 8bit XL/XE and
change the interface to one for an ST and it will now work on the ST
(after a format).
The two most widely used controllers, and I might add, ARE REALLY THE
BEST, are made by Adaptek they are designed with the user in mind and
provide for expansion for the future.

While Adaptek does offer other controllers, the 4000 series seem to be the

to the drive.
These hard disk systems are special in one way, they have embedded
controllers.

* These devices are SASI and are slowly fading into the sunset......
ADAPTEK CONTROLLERS
===================
ACB4000A / ACB4070 are highly recomended and of excellent design. These
controllers will handle most any application.
HARD DISK INTERFACE
===================
There are three types available for the ST: ICD, Supra, and Berkley
THE ICD ST HOST ADAPTER INTERFACE
=================================
The Host Adapter is designed for the 16 bit ST hard drive system or for
most anything you care to couple to it...ie, tape backup and hard disk
and laser printer etc..
The host adapter interface is also equipped with an setable clock
made non-volatile thru the use of a lithium battery.
SUPRA
-----
All of Supra's interfaces are quite good, and as flexible and have the
same features as ICD in fact, at this time we reccomend the use of the
Supra system as it has more recent updates. Also, Supra provides
additional chaining thru scsi ports.
The configurations for the hard disk systems are variable, for example,
if you wished to use the stand alone system with a different computer you
would be able to do so simply by changing the interface.
Expandable means you can add another drive at a later date in the
existing cabinet without major circuitry changes. The proper cabinets are
those made for the IBM twin half height disk drives. They take up less of
a footprint than the SH204 and have a 70watt switching power supply and
blower included in the cost. Also included in the price is a blank panel
for the empty drive space if you are using only 1 half height drive to
start with. The cabinet fits like a glove not like an old garbage bag..

-TANGERINE DREAM-
=================
REVIEW SEPT 24 1988 CONCERT, BERKELEY CA.
For those of you out there who do not know who or what
Tangerine Dream are, here is a short explanation.
Tangerine Dream are a 3 piece sythesizer group from Germany. They
have been around making music since the late 60s/early 70s. I
have been listening to them since around 1975. They are probably the
pioneers of modern electronic music. They have put out at least
20 albums and many soundtracks. The band has gone through lineup
changes a few times and of the original three only one remains,
Edgar Froose. They have retained much of their original style
although they have evolved as any group worth their artistic
talent should. As electronics itself has evolved in music so
comes the use of computers in electronic music. Tangerine Dream
has adopted the Atari ST into their world to control much of what
they do. The computers (they use 11, 5 in concert) control sound
patches and rhythms and do a lot of musical housekeeping.
Tangerine Dream performed live at the Berkeley Community
Theatre, Saturday September 24th. It was one of three tour stops in
California. They have criss-crossed their way from Canada through
the States and will finish up in Vancover BC this week. The tour
promoted their latest album 'Optical Race'. It states on the
back side of the album cover 'This album has been produced
on the ATARI ST using Steinberg/Jones Software'. Even though I
have been following them for many years, this was the first
concert of theirs I had ever seen. Atari Computers sponsored the
tour and you could tell the moment that you walked into the
theatre. We were greeted with a big banner with Tangerine Dream
and Atari logos plastered all over it, a treat for an Atari freak
like myself. The stage setup consisted of three stations with
many synths and a couple of ST's (Megas I think) at each one.
What a sight for these Atari lovin eyes, especially with
thousands of Tangerine Dream fans all around. Enuf' of this, on
to the performance.
Andy Summers (ex-Police guitarist) opened up the show for them
with a very short set (thank heaven), just a rhythm machine and a
guitar. It was not exciting. When Tangerine Dream began their
set they were greeted with cheers that told you were in
the company of some very excited and loyal fans. I had not known
they had such a following. The music was very well projected with
the complexity and synchronization that one rarely has the
pleasure of witnessing. About half of the material was from the
'Optical Race' album. The other must have been new, at least to
me. The rhythm tracks, synth drum sounds and lead keyboard work
was simply amazing. I found myself chuckling with the enjoyment
that I was in, sometimes wondering if I was listening to a giant
CD player. That is how clear and precise it all was. The music
was more mainstream, rhythmically 'rolling' and more intricate
than their past works I am accustomed to. Their previous stuff
was more spacy and eerie with a more heavy,synthetic sound. They
had a great light show that seemed to be controlled by one of the
sythesizers. Lights flashing,moving and pulsating creating
something visual out of the audio. A few times we were shown the
individual qualities of the group with piano solos and Edgar
Froose's electric guitar work. They were called out for two
encores which they played two or three more numbers each. It was
a evening that I enjoyed very much. I hope some of you also
share my feelings about the concert and were able to attend one
of the many tour stops. Some diehard Tangerine Dream fans are undoubtedly
feeling that they are maybe going commercial with their new sound.
Well, Yes I guess they are. But it is a healthy step forward to
reach a wider audience than they have had and they sure sound
GREAT. Don't get scared off, they are not nearly as commercial as
say Windham Hill, and I consider myself THE diehard Tangerine
Dream fan. I wish I could explain to you better what Tangerine
Dream are all about. The only way to know is to experience them
yourself. If you are a seasoned fan of electronic music buy
anything and everything by them. If you are new to the field or
are more mainstream (normal?) in your musical tastes then start
with 'Optical Race' and go backwards from their. If you share my
interest in Tangerine Dream drop me a line.
If anyone can tell me where I may find the video that they were
selling at the concert please let me know.

Professional GEM by Tim Oren
Column #6 - Raster Operations
This installment of ST PRO GEM, is devoted to explaining the
raster, or "bit-blit" portion of the Atari ST's VDI functions.
Please note that this is NOT an attempt to show how to write
directly to the video memory, although you will be able to deduce a
great deal from the discussion.
DEFINING TERMS
To understand VDI raster operations, you need to understand the
jargon used to describe them. (Many programmers will be tempted to
skip this section and go directly to the code. Please don't do it
this time: Learning the jargon is the larger half of understanding the
raster operations!)
In VDI terms a raster area is simply a chunk of contiguous words of
memory, defining a bit image. This chunk is called a "form". A form
may reside in the ST's video map area or it may be in the data area of
your application. Forms are roughly analogous to "blits" or "sprites"
on other systems. (Note, however, that there is no sprite hardware on
the ST.)
Unlike other systems, there is NO predefined organization of the
raster form. Instead, you determine the internal layout of the form
with an auxiliary data structure called the MFDB, or Memory Form
Definition Block. Before going into the details of the MFDB, we need
to look at the various format options. Their distinguishing features
are monochrome vs. color, standard vs. device-specific and even-word
vs. fringed.
MONOCHROME VS. COLOR
Although these terms are standard, it might be better to say
"single-color vs. multi-color". What we are actually defining is the
number of bits which correspond to each dot, or pixel, on the screen.
In the ST, there are three possible answers. The high-resolution mode
has one bit per pixel, because there is only one "color": white.
In the medium resolution color mode, there are four possible colors
for each pixel. Therefore, it takes two bits to represent each dot on
the screen. (The actual colors which appear are determined by the
settings of the ST's pallette registers.)
In the low resolution color mode, sixteen colors are generated,
requiring four bits per pixel. Notice that as the number of bits per
pixel has been doubled for each mode, so the number of pixels on the
screen has been halved: 640 by 400 for monochrome, 640 by 200 for
medium-res, and 320 by 200 by low-res. In this way the ST always uses
the same amount of video RAM: 32K.
Now we have determined how many bits are needed for each pixel, but
not how they are laid out within the form. To find this out, we have
to see whether the form is device-dependent or not.
STANDARD VS. DEVICE-SPECIFIC FORMAT
The standard raster form format is a constant layout which is the
same for all GEM systems. A device-specific form is one which is
stored in the internal format of a particular GEM system. Just as the
ST has three different screen modes, so it has three different
device-specific form formats. We will look at standard form first,
then the ST-specific forms.
First, it's reasonable to ask why a standard format is used. Its
main function is to establish a portability method between various GEM
systems. For instance, an icon created in standard format on an IBM
PC GEM setup can be moved to the ST, or a GEM Paint picture from an
AT&T 6300 could be loaded into the ST version of Paint.
The standard format has some uses even if you only work with the
ST, because it gives a method of moving your application's icons and
images amongst the three different screen modes. To be sure, there
are limits to this. Since there are different numbers of pixels in
the different modes, an icon built in the high-resolution mode will
appear twice as large in low-res mode, and would appear oblong in
medium-res. (You can see this effect in the ST Desktop's icons.)
Also, colors defined in the lower resolutions will be useless in
monochrome.
The standard monochrome format uses a one-bit to represent black,
and uses a zero for white. It is assumed that the form begins at the
upper left of the raster area, and is written a word at a time left to
right on each row, with the rows being output top to bottom. Within
each word, the most significant bit is the left-most on the screen.
The standard color form uses a storage method called "color
planes". The high-order bits for all of the pixels are stored just as
for monochrome, followed by the next-lowest bit in another contiguous
block, and so on until all of the necessary color bits have been
stored.
For example, on a 16-color system, there would be four different
planes. The color of the upper-leftmost bit in the form would be
determined by concatenating the high-order bit in the first word of
each plane of the form.
The system dependent form for the ST's monochrome mode is very
simple: it is identical to the standard form! This occurs because the
ST uses a "reverse-video" setup in monochrome mode, with the
background set to white.
The video organization of the ST's color modes is more complicated.
It uses an "interleaved plane" system to store the bits which make up
a pixel. In the low-resolution mode, every four words define the
values of 16 pixels. The high-order bits of the four words are merged
to form the left-most pixel, followed by the next lower bit of each
word, and so on. This method is called interleaving because the
usually separate color planes described above have been shuffled
together in memory.
The organization of the ST's medium-resolution mode is similar to
low-res, except the only two words are taken at a time. These are
merged to create the two bits needed to address four colors.
You should note that the actual color produced by a particular
pixel value is NOT fixed. The ST uses a color remapping system called
a palette. The pixel value in memory is used to address a hardware
register in the palette which contains the actual RGB levels to be
sent to the display. Programs may set the palette registers with BIOS
calls, or the user may alter its settings with the Control Panel desk
accessory. Generally, palette zero (background) is left as white, and
the highest numbered palette is black.
EVEN-WORD VS. FRINGES
A form always begins on a word boundary, and is always stored with
an integral number of words per row. However, it is possible to use
only a portion of the final word. This partial word is called a
"fringe". If, for instance, you had a form 40 pixels wide, it would
be stored with four words per row: three whole words, and one word
with the eight pixel fringe in its upper byte.
MFDBs
Now we can intelligently define the elements of the MFDB. Its
exact C structure definition will be found in the download. The
fd_nplanes entry determines the color scheme: a value of one is
monochrome, more than one denotes a color form. If fd_stand is zero,
then the form is device-specific, otherwise it is in standard format.
The fd_w and fd_h fields contain the pixel width and height of the
form respectively. Fd_wdwidth is the width of a row in words. If
fd_w is not exactly equal to sixteen times fd_wdwidth, then the form
has a fringe.
Finally, fd_addr is the 32-bit memory address of the form itself.
Zero is a special value for fd_addr. It denotes that this MFDB is for
the video memory itself. In this case, the VDI substitutes the actual
address of the screen, and it ignores ALL of the other parameters.
They are replaced with the size of the whole screen and number of
planes in the current mode, and the form is (of course) in
device-specific format.
This implies that any MFDB which points at the screen can only
address the entire screen. This is not a problem, however, since the
the VDI raster calls allow you to select a rectangular region within
the form. (A note to advanced programmers: If this situation is
annoying, you can retrieve the address of the ST's video area from low
memory, add an appropriate offset, and substitute it into the MFDB
yourself to address a portion of the screen.)
LET'S OPERATE
Now we can look at the VDI raster operations themselves. There are
actually three: transform form, copy raster opaque, and copy raster
transparent. Both copy raster functions can perform a variety of
logic operatoins during the copy.
TRANSFORM FORM
The purpose of this operation is to change the format of a form:
from standard to device-specific, or vice-versa. The calling sequence
is:
vr_trnfm(vdi_handle,source,dest);
where source and dest are each pointers to MFDBs. They ARE allowed to
be the same. Transform form checks the fd_stand flag in the source
MFDB, toggles it and writes it into the destination MFDB after
rewriting the form itself. Note that transform form CANNOT change the
number of color planes in a form: fd_nplanes must be identical in the
two MFDBs.
If you are writing an application to run on the ST only, you will
probably be able to avoid transform form entirely. Images and icons
are stored within resources as standard forms, but since they are
monochrome, they will work "as is" with the ST.
If you may want to move your program or picture files to another
GEM system, then you will need transform form. Screen images can be
transformed to standard format and stored to disk. Another system
with the same number of color planes could the read the files, and
transform the image to ITS internal format with transform form.
A GEM application which will be moved to other systems needs to
contain code to transform the images and icons within its resource,
since standard and device-specific formats will not always coincide.
If you are in this situation, you will find several utilities in
the download which you can use to transform G_ICON and G_IMAGE
objects. There is also a routine which may be used with map_tree()
from the last column in order to transform all of the images and icons
in a resource tree at once.
COPY RASTER OPAQUE
This operation copies all or part of the source form into the
destination form. Both the source and destination forms must be in
device-specific form. Copy raster opaque is for moving information
between "like" forms, that is, it can copy from monochrome to
monochrome, or between color forms with the same number of planes.
The calling format is:
vro_cpyfm(vdi_handle, mode, pxy, source, dest);
