1 Technical Info
My email address will change more than once nexttime. Due to this reason I
have an alias, pointing to my actual location - and if it's in the
MAUS-Net: G.Castan@physik.uni-stuttgart.de
For easy location of this document at servers and mailboxes, I ask for
using the following name(s) and saving the ascii AND TeX versions:
FILENAME = gdosi23e
CR+LF should be used when saving at UNIX-Fileservers too, not just LF
2 Introduction
Actually I'm writing a program, that makes his print-out via GDOS. Looking
for printer drivers I faced the problem, that many times no documentation is
included to the drivers.
Otherwise it may happen that there are different drivers with the same name.
Here I have briefly collected my experiences with printer drivers.
This collection doesn't generally want to describe coders how to use
printer drivers (except to problems not mentioned in literature). And you
wont find information about the concept or how to install printer drivers.
To get this refer to the list at the end of this FAQ.
What I want to exclaim here is more information about the several drivers:
o Where are the drivers available?
o How to distinguish them?
o What are the problem with them?
o Which drivers can be used for certain printers?
If anybody has more experience or questions, please write me. I will face
the work to update this FAQ.

3 Motivation
With GDOS it took me ~2 hours of coding, to get the screen-output to the
printer in maximum quality. And (almost) with no extra work I get output to
printers I even don't know.
I there's anybody who wants to write a program with printing options, should
better care of the main job of the programm.
Nobody wants to pay for printer drivers if there's another program that
didn't take the coder extra work with such stuff making this program less
expensive (and surely better).
The User has - besides the lower price - another advantage. If he uses
several programs he need place for the driver and the fonts only one time on
the disc.
SpeedoGDOS is available from Atari shops (Atari Competence Center in
Germany) now.
The (qualified) feedback to my FAQ has - compared to autumn '92 - raised
remarkable. Due to Speedo the interest in GDOS coming from the coders seems
to be bigger.

Note: The drivers named HP_LJET and DESKJET can be used for (HP compatible)
ink and laser printers. The difference is in the transfer to the printer:
Packed (p.) or not packed (n.p.). 'Delta' means that the data is delta
packed.
PAINTJET:
180X180: 2-8 colo(u)rs
90x90: 16 colo(u)rs
MT90 is made by Patrick Dubbrow.
Using ink drivers produces a problem with bitmap fonts. Using 300dpi all is
ok. But 360dpi fonts are optimised for best efforts with pin printers having
thick pins. Using ink printers makes the fonts look much too thin.
Solution: either use 300 [ 600, 1200 :-) ] or exclusively use vector fonts

SLM_HS is a SLM driver for the Falcon (when using the Heatseeker interface)
5.6 Screen drivers
The screen is (if VDI functions are used) seen as an output device just
like printer, plotter etc. That's why fonts for the screen can be installed
in ASSIGN.SYS just like for printers.
Normally this isn't remarked because the drivers are in ROM. But they can be
used like printer drivers.
Note: For system fonts only (like the original ones) non proportional fonts
with a 8*8 or 8*16 matrix can be used. That's limited by the AES not VDI.
With newer AES (from 4.0?) it's no problem to use fonts of free choice
(Variable AE_FONTID and AE_FONTSIZE in GEM.CNF, see [15]). Coders should
make sure their programs can take that. (even like scrollbars of free width)
Bitmap fonts not assigned for screen driver 1 are not available for other
screen drivers.
5.6.1 LineA
The so-called LineA-routines are subprograms of the screen drivers from the
ST series, to bee seen undocumented. This is the hardware depending part of
these drivers.
The attentive readers discovers it: Exchanging the drivers removes the
LinaA routines too. As happened with the TT for example.
So never use them!
/Reading/ acces can be taken to the LinaA-variables. But Why?
5.6.2 Setscreen & Getscreen
These XBIOS-Functions (mostly Setscreen) should'nt be used.
But what am I talking. For those useing them or those being tortured
because someone did it:
The video hardware of 1040STE and Mega STE has an hardware bug. When defining
a new physbase with Setscreen (and if it's the same gotten with Getscreen),
it may happen that the screen is 'folded'. This happens due to the movement
of a register at a special moment, which is only allowed to be moved at
special phases of the screen output.
What has to be done?
Users: The programs NVDI and FALT_OFF stop this error. Or give this FAQ to
coder.
Coders: Either even don't use Setscreen.
If You use it though: If physbase isn't changed, the value taken
with Getscreen may not be used. Use the
value -1 than physbase!
5.6.3 NVDI and WARP 9
There are two often used programs exchanging the ROM drivers: NVDI and WARP
9 (earlier QuickST). TurboST was distributed by BELA but isn't updated no
more.
If these are used once, one will never want to miss them: the Desktop seems
to be terribly slow. I will never want to work without NVDI on my Atari.
Others say the same about WARP 9.
NVDI uses strongly optimised drivers for the ST and TT resolutions. Sadly I
don't know which drivers are used by WARP 9.
NVDI is available from Behne & Behne and contains not only the drivers but a
GDOS and a manual describing exactly all VDI calls.
WARP 9 is available from CodeHead.
Due to this NVDI is spread in Germany and WARP 9 in the US
Different to NVDI WARP 9 only speeds up the text output. Grafics stay slow
as before. AND the newest version doesn't work with MultiTOS. It Works on
the Falcon too, but I don't know if it supports *all* resolutions there
(Like with Screenblaster, BlowUp030 or others)

IMG-0300 can be copied (non commercial). The other IMG-0??? drivers are by
SciLab. ZEBRA is for the Zebra Labelprinter.
5.7.1 Memory drivers
A memory driver doesn't do anything else than a screen driver (see [15] and
[13]). But the output doesn't get to the screen driver, but in another
memory to be influenced there.
The usual v_openwk binding doesn't have all parameters needed to open this
driver. If not included to the language this binding must be made by
yourself. A listing is found at [15].
The memory driver listed above is only capable of b/w output only and has
a logical resolution of 300dpi. The (matrix) drivers tested by me have no
problems with fonts installed that are for other other drivers. The memory
driver should take screen fonts - due to the 300dpi.
Problem could appear because of the aspect ratio (relation of pixel width to
height) - normally not similar to the screen resolution.
Due to this circles can be displayed as ellipses.
With NVDI V2.5 or higher output can be made to offscreen bitmaps. There can
be made any GDOS outputs and the result can be copied in the screen windows.
5.7.2 Plotter drivers
A HPGL driver seems to be distributed with the program DATA. On PD disk ST
458 (German PD series) is one too. If I get more about it I'll include this
info here.
5.7.3 NVDI 3 drivers
NVDI 3 has its own driver concept. Only a small quantity of drivers is
included, but they're very fast, small and flexible.
The drivers are:
___________________________
|_Treiber______|_Datum____|
| PINPRN.SYS | 19.10.94 |
| PAGEPRN.SYS | 19.10.94 |
| IMG.SYS | 30.10.94 |
| MEMORY.SYS | 18.10.94 |
| META.SYS | 18.10.94 |
|_ATARILS.SYS__|_18.10.94_|
Depending to the colo(u)r printing capability of a printer (this can be set
in the MAKEPRN.APP), the drivers have to use different offscreen drivers to
create the graphics (this can't be found in the manual coming with NVDI 3
[Stef: A manual like for NVDI 2.x is in work]
Gerd: It will be an ascii file for FTP servers and BBS, not a printed one)
The Offscreen drivers are:
_____________________________________
|_Treiber_______|_Datum____|Farben__|
| OFF002.NOD | 06.11.94 | 2 |
| OFF004IP.NOD | 06.11.94 | 4 |
| OFF016IP.NOD | 06.11.94 | 16 |
| OFF256IP.NOD | 06.11.94 | 256 |
|_OFF32KFL.NOD__|_06.11.94_|_32768__|
The actual NVDI 3.01 can't handle colo(u)r printing though :-(
3.02 will.
The flexibility to create a driver's INF for printers is great. To code a
driver for SpeedoGDOS you have to become a developer for SpeedoGDOS.
It isn't that easy ...
With NVDI you only have to enter you printer's codes in MAKEPRN.APP. So you
only have to check you printer's manual, not learn or do C coding.
The codes driving the printer are saved in the INF files belonging to each
driver. A flaw is that these assignments aren't simply exchangeable.
There's no documentation about the file format and no program to extract or
add codes yet. The only way is to exchange the complete INF file.
Another problem not even noted in the manual occurs when assigning pixel
fonts in the ASSIGN.SYS. Guess that you have assigned 180dpi fonts to the
PINPRN.SYS. It's easy to change the output resolution to 360dpi by the CPX.
*Then* the printout will be catastrofugly.
A workaround is to duplicate the driver with another name (close to the
first ...) and assign this one to in the ASSIGN.SYS too, but with different
fonts.
At last I think those drivers conceptionally are much better compared to
the ones coming with SpeedoGDOS 5. No colour printing yet though.
5.8 What's missing
I don't know drivers using the abilities of the following printers:
o Canon BJC 600 - A colour printer with 4 heads (CMYK) 64 nozzles each.
In the colour mode he's compatible to:
- Canon BJC 800
- Epson LQ 2550/2500
It's resolution is 360x360. I dont's know any GDOS driver
supporting the BJC's capabilities directly (or via
compatibility mode) when using colours.
6 Errors
Errors in the printers drivers - that I know - are the following:
1 These drivers display Fonts with the attribute 'light'
2 Doesn't work on TT
3 The EXTENDED ENQUIRE FUNCTION (VDI 102, vq_extnd) doesn't give back the
parameters as listed in the German 'Profibuch' (Jankowski, Rabich,
Reschke - Sybex)
4 Using the attributes 'italic' and 'outlined' the letters of bitmap fonts
are cut off on the right side. This error appears independent from other
attributes being used.
This error was in the Libraries of the driver sources from Atari and
seems to be included in all drivers except to NVDI and SpeedoGDOS.
If theres nothing written about an error I don't know if this error appears
or not.
Seems it's no accident, that Xact only uses the attributes 'fat', 'italic'
and 'underlined'. (See [4])
Another reason against using 'outlined' is the following:
If You make a driver calculate an outlined font from a normal one it get's
'wider' by two pixels. Due to the reason that a pixel has a width depen-
ding to the resolution (other than a fitted font) a text gets different
widthes in each resolution. But who wants to have different textformat on
different printers? The only way to stop this is letterspacing -
typographic 'bullshit'.
7 Fonts
First: What's the difference between a fonts and a face?
When calling a font selector there may be Swiss 721, Swiss 721 italic,
Swiss 721 Bold and Swiss 721 Bold Italic. These are 4 faces, alltogether
creating a font.
This separation isn't that simple at bitmap fonts, because all attributes are
created from only one file (this can be made with vector fonts too, but it's
quite nonsens In my opinion). That's why I first didn't note that this
attribute creation is buggy in some versions of SpeedoGDOS (see 13.3.3).
Me I'm not always using this separation of font and face in this FAQ.
Especially in the chapter about font formats.
7.1 Bitmap fonts
The fonts used are bitmap fonts in the DR standard format. They have to be
saved in Intel format. Motorola format isn't supported by any GDOS.
(See [1] and appendix)
GDOS bitmap fonts have their width information defined in both, screen font
and printer fonts. Sadly the designers were a bit too zealous and fitted the
width of the sreen fonts to make them look very beautiful. They've done a
good job, but they're not similar to the printer fonts and don't allow
WYSIWYG.
There are many fonts on the Internet only for the screen and maybe useable
for one printer. Everybody using these fonts should know that he can't print
documents in an acceptable quality via GDOS.
But in the Atari and former BELA package there are containedthe fonts for
all printer drivers in this package (the 360*360dpi fonts are missing in the
Atari package). If you have a useable program you can print every document
with every driver.
7.2 Vector fonts
Vector fonts don't use pixels, they are created with algorithms - supported
by shapes and hints. These algorithms (see METAFONT for a good example) make
the fonts copyrighted like normal programs. (See [24] for this)
Here I'll write a bit about vector formats. Why should a pure user try to
understand it? Nowaydays you'll just get a cheap Font CD, choose 17 of the
most interesting fonts for your first poster an print out the creation.
Problems are: I have one face in different formats. Which one should I
take? Sometimes I have problems on screen, when I print out something or
only when using a specific size. So what?
(When you have 17 Garamond styles from 17 different distributors it's
better to read a magazine about typography or DTP to get help)
7.2.1 FSM-GDOS fonts
The vector fonts with the old FSM-GDOS format are named with OTL.
These fonts and drivers should'nt be used no more and are listed to only for
completion of this FAQ.
7.2.2 Bitstream Speedo onts
The vector fonts in SpeedoGDOS format are named with SPD.
They are supported by all SpeedoGDOS releases and by NVDI 3.0 or higher.
7.2.3 Type 1 fonts
Type 1 fonts are available for MacIntosh abd MS-DOS/Windows. They only have
differences in the internal representation, not in the information.
At least one of these formats is supported by SpeedoGDOS from V5.0a. But I
already found some that SpeedoGDOS 5.0a can't display.
7.2.4 TrueType fonts
This format is available for MacIntosh and MS-DOS/Windows too. The MS-DOS
format is a superset of the MacIntosh format.
SpeedoGDOS from V5.0a can handle both, no matter if it's for MacIntosh or
MS-DOS/Windows.
NVDI from V3.0 is able to handle it too.
7.2.5 Calamus fonts
Can YOU tell me more about these?
7.3 Comparison of vector formats
(This chapter is to be completed yet)
There's no noncommercial program on any platform that can convert one format
into the other. A lot of fonts are only available in one format.
But what makes a conversion so difficult? To ask different: Which infor-
mations are stored by which way?
7.3.1 Curves
First the shape of the chars should be saved. But that for many ways are
used:
Type 1: Uses cubic Bezier curves aka cubic B-splines
TrueType: Uses square Bezier curves aka square B-splines
Speedo: Uses cubic Bezier curves aka cubic B-splines
(How has v_bez_qual to be set to make an output with
v_getoutline and v_bez_fill have the same result as the font engine?)
Square B-splines are much faster than cubic Bezier curves but you have to
store about 4 times as much points to achieve the same quality.
7.3.2 Hints
The next problem is the display on media with low resolution. For a neutral
observer Speedo fonts always look quite good on the screen (well, some fonts
are ugly by nature).
But I've found TrueType fonts that look as ugly as nothing else on the
screen. For example the two vertical lines of an 'n' are not the same, one
is 1 pixel and the other is 2 pixels thick.
The way to prevent those errors are hints. This method is used by Speedo,
Type 1 and TrueType (but not by Type 3 and CFN). But hints given by the
format don't mean that they're used too!
So, finally: All these three font types can look very good on the screen,
Type 3 and CFN can't [ever tried to print CFNs on a printer with less than
360x360dpi?]
Now I've noted, what hints are doing and in which formats they're used. But
*how* do they work? Specific parts of a character have a specific >>job<<,
like serif, bow etc. This is saved besides the font's outline. This way the
scaler e.g. can create similar vertical lines of a >n<. More is found in
[26]
Type 1 only can handle very few different hints compared to other formats.
Note:
with v_getoutline you get the outlines in the workstation's actual
resolution. Remember that using hints depend of the resolution. Plans
exist to make v_getoutline independent from the actual hint size.
7.3.3 Internal resolution
After the problem with low resolution now there's the problem with the high
resolution. Even if you think there shouldn't be any; there are! (See [27]
too)
To display a vector font first an internal system of coordinates has to be
selected. To do this the em-square is devided in units. CFN has one from
0 to 16000, Type 1 (which was created when there were no high-res printers)
one from 0 to thousand. Due to this there are 'corners' visible at large
letters or high resolutions (in the professional league)
Referring to [25] the internal resolution can be raised by the
DIV operator. But this has to be supported by the font editor.
(Is this done regularly and does the scaler get remarkably
slower by this?
CFN can make the big deal here.
(Which internal resolutions do Speedo, TrueType and OTL have? Is the
Bitstream format mentioned in [25] identical to the Speedo format?)
7.3.4 Linear and optical scaling
[Gerd: even the German readers didn't understand the original German
version of the following paragraph. Wait for version 2.4 of this FAQ.]
Do we now have - with the description of the shape, a high internal
resolution and the hints - a scalable font? Sure not!
A font being designed for 16pt has a totally different shape as a doubled
8pt fonts (see Knuth: The METAFONT book; Kopka: LaTeX etc.). A well designed
font isn't linear scalable.
In large fonts vertical lines are much thicker than the empty space between
them. But this information for optical scaling can be saved in a font too.
So a font, being 20 pixels high on the screen (this is usually a large font)
should look different to one being 20 pixels high on a laser printer (this
is a small font that should have small vertical lines).
(Which formats do save these informations?
to COMPO and 2B:
If it's saved in Speedo, Type 1 or TrueType: How can I tell SpeedoGDOS or
NVDI that a printout has to be downsized in a photomechanical way and has
to be scaled different to a font that don't have to be changed?
Does this make it useful for programs setting the font size in pixels and
points too? If it's so, then which has to to set first)
There are rumours about Type1 fonts supporting optical scaling automaitcally.
But I think this should be supported by the font engine because there may be
one window with a title and one with an enlarged document. Here scaling has
to be made different - with same size of pixels. This the font and the font
engine CAN'T know.
7.4 Font Format convertition
From what I wrote above I hope you'll realize that converting a font from
one format to another is about as easy as converting a highly optimized
program from one language to another ...
Problems:
o The only converting program I (Stefan) know for Atari
is TypetoType fby Hasso Baudis, converting Type1 to CFN
o There isn't any program on any platform that is accepted by the
comp.fonts community (according to the comp.fonts FAQ)
o For a program capable of converting fonts you'll pay a big
amount of money. But even good programs need manual corrections.
Looking for a PD or shareware program won't be
successfull ...

Drivers in parantheses work but don't use the ability of the printer totally.
This means - for 24pin printers - that these are used in 9pin mode. At
HP compatible Laser and Ink printers this means that the data isn't packed
though being supported by the printers.
Some Deskjet drivers are told to make problems. In this case try the Laser-
jet driver. The printing takes longer then (due to more data) but the
problems should be removed then.
The BJ10 drivers use the Proprinter emulation. Don't use them in the epson
mode!
The Stylus shouldn't be used with 24needle drivers. The needles overlap
(the ink dots of the stylus don't) and so the drivers just don't print some
dots.
The meaning of compatible normally is made by the producers of the
compatible printers.
Notes:
o If You don't find your printer in the list and knows a fitting driver,
please write me a note.
o Try other drivers even if you have found one fitting to your printer.
o Of course the FontGDOS drivers have a lot of problems with the memory.
But the speed of'em is faster than the other (Speedo not considered).

This list is no commercial. I'll include every program I get to know.
(Comment by the Translator: Sorry for mentioning Atari Works three times,
but I wanted to keep the 'Text/DTP' and 'Spreadsheet' Chapters')
Notes:
o Programs listed in the Speedo column with 'y*' support Speedo but don't
use it - don't output text too.
o 7up only uses non proportional fonts (e.g. Monospace 821 from Speedo)
o Xact can print Speedo fonts without Speedo too.
o FSM-GDOS is included in the Wordflair II package.
o Platon only outputs metafiles via GDOS.
o I didn't make it to print via GDOS in OPUS.
(I've been told, OPUS doesn't chose the fonts it can handle with,
and doesn't print if even one of these fonts is installed. See 7.1 too)
o Programs only printing via device 21 (like OPUS and CLA are out! (see
16.2 too)
o Tempus Word only supports Speedo Fonts but prints with its own drivers
This seems to be due to the capablity of handling CFN and its own fonts
o That's Write & 1st WordPlus 4 both can use Speedo fonts without
Speedo. TW 4 will be able to use TTF and Type 1 without SpeedoGDOS
(well, TW and the SpeedoGDOS 5.x font extension to TTF and Type 1
is created by the same coders ...)

Gerd: but not on any FTP-Server)
10 Utilities
10.1 fontfix
Problem: The font height is included wrong at some fonts. fontfix discovers
this error and corrights it.
In the Internet fontfix can be found here:
ftp.uni-muenster.de /pub/atari/Applications/Dtp/Fonts/Gdos
ftp.cs.tu-berlin.de /pub/atari/utils
10.2 Outline fonts
Outline Fonts Accessory by CJG
What for: This utility edits the EXTEND.SYS for SpeedoGDOS. This file
contains a description of the volume from the Speedo caches, the
fonts and the font-sizes. The caches can be saved to disc and loaded
again from there too.
A good done program except to the preset cache sizes fitted to
FSM-GDOS not Speedo.
Filename: OUTLINE.PRG alias OUTLINE.ACC, 67644 Bytes (49254Bytes at
Speedo 5)
Spread with SpeedoGDOS.
(Why doesn't Atari make it to make programs including a display of the
version?)
10.3 Printer drivers
GDOS Devices Accessory by CJG
What for: To edit the ASSIGN.SYS
Filename: DRIVERS.PRG alias DRIVERS.ACC, 64878 Bytes (41592Bytes with
Speedo 5)
Before starting this program it's better to create a backup of the
ASSIGN.SYS!
The (at least) two reasons are the following:
1. The informations about the bitmap fonts are removed without comment.
2. ASSIGN.SYS is removed by a new one if 'Benutzereigen'-'Hinzufuegen' (in
the German release) is selected wihtout any chance to get it back.
(The English Version should have a Dialog like 'Own drivers' 'Add' or
similar). To all coders: Don't copy that style!
If this utility should display no drivers sometimes simply start ASSIGN.PRG
(see next subsection)
DRIVERS.PRG/ACC only displays the Speedo drivers of my collection. Does
anybody know, how it does this? Even it doesn't display the Filename but a
name being included as string in the driver. How does one get there?
10.4 ASSIGN
ASSIGN 1.0d is by Dirk Sabiwalsky (PD).
It tests three things:
o Are there several fonts using the same ID and have different Names
(Typefaces)?
o Are there several fonts using the same ID and the same Pixelheight?
o Are there several fonts with the same name (Typeface) and different
IDs?
10.5 FONTCHK
FONTCHK tests GDOS fonts if they have possible errors.
It's spread with ProList for example.
10.6 FONTCNV
Converts GDOS fonts from Motorola to Intel format.
Comes with ProList too.
10.7 GEMFont
Fonteditor being able to read Signum- and PK (TeX)- Fonts too.
Internet: ftp.tu-clausthal.de:pub/atari/systools/gdos/gemfo120.lzh
Use the chance to get a new unlzh or lhxarc.
10.8 FontMonger
Converter and editor for different vector formats including Speedo. Only
works on IBMs or MAC though.
10.9 Font-ID
Font-ID is a little freeware tool made by Frank Schneider. In a window it
displays the fonts installed with GDOS or SpeedoGDOS including the Font-ID
in different sizes. So you can get an overview when you don't have a program
with font selector/ID display function at the moment.
10.10 X4U
Speedo fonts have much more glyphs than the ones displayed in the ASCII
charset. With this program by Peter Hellinger you can setup, which char is
to be used at which ASCII code. It's distributed by R.O.M.
11 Font selectors
We all know this useful thing about file selectors:
The Operating system soesn't only offer a file selector, it's got an interface
to use own file selectors in every application.
A scaled interface for FONT selectors doesn't exist, normally they're
offering their jobs by cookies. The work to make a program support font
selectors via cookies is much smaller than writing one for yourself. If there
wouldn't ... but let's take a look at the candidates first.
11.1 UFSL
UFSL from Michael Thaenitz is freeware and is allowed to be distributed with
any application. The last version is 0.97 from April 30th 1994.
Fonts (faces) and size can be selected comfartable. But I didn't get a face
displayed after selecting a free size.
Attributs are missing and the dialoge is only modal.
UFSL sadly isn't in development no more.
11.2 XUFSL
This font selector is the one with most features - compared to the other
ones mentioned here. It even can handle Speedo 5 (and NVDI 3, note by
Stefan) too.
Version 1.03 is stable and UFSL compatible. The following setting are
possible:
- Font size
- Kerning informations (Pair & Track kerning)
- Skewing angle
- Color
- Attributes
*And* it is (almost) totally keyboard controllable and shows the actual
font ID.
At first test I only found some non-important flaws (flat hand on popup).
But it would be a nice feature to (totally) hide disabled setting.
This file selector is to be supported further on (1.05 is the actual
release) and - public - beta, until there's a fix definition about
font selectors.
11.3 Magic from Peter Hellinger
This selector is part of Magic 4.00 from Peter Hellinger and not available
separately. Magic itself - NOT MagiC! the multitasking OS - can be copied
freely. But the information how to use it must be paid.
It's nice that this selector can be set in a non modal dialog, FlyDial or
normal dialog. Scrolling through the list is fast too.
Attributes aren't selectable and the size selection in the edit line isn't
acceptable the way it's done.
The selector only can be used when the event handling is completely done by
Magic, what makes the coder use a fixed code structure (working parts must be
rewritten, other things don't work anymore) and produces new errors.
11.4 FontSel
FontSel from Holger Weets is totally cmpatible to UFSL for the programs.
It's small size and the selecteable attributes are a very nice feature.
Version 1.00 from May, 11th 1994 only shows the System Font when using
Speedo 5.0a.
11.5 Minimum requirements
A Font selector should work with all OS-releases (TOS, MiNT, MultiTOS,
MagiC!, Geneva). Plus with every video hardware supported by the VDI and
should show each font available from every GDOS version. (Pixel fonts,
Speedo fonts, Type1 and TrueType).
11.6 Characteristics liked to be seen
Its quite complicated to make the user set further characteristics of fonts
in an extra dialog. So, at least the standard attributes (bold,
outlined, ...) should be directly made available. If a program doesn't
support them they should be made non selectable.
Same with the skew angle.
Not every program can handle all fonts. According to this every program
must be able to set, which faces have to be invisible or disabled.
An example:
Some programs (like 7up) only use non proportional fonts.
A further feature (but not exlusively, due to BASIC) it should be possible
to pipe a procedure variable to the selector setting the kind of displaying
for each face.
It would be nice if the program could set the selector in a window or normal
dialog too. It can be done much easier and more flexible than in Magic.
The font selector opens a window in the calling program's name and gives back
the window handle to it. The application further handles the events and if one
is for the font selector's window it is passed to it via a procedure call. This
simple mechanism enables the use of multiple (system wide) selectors, colour
pickers (and more) distributed by different producers being in windows on the
screen the same time.
Once more:
This parallel work only is possible when every selector doesn't use
evnt_multi.
Finally an application should be able to set if it doesn't matter if a font is
proportional or not (the user can have displayed it if he really wants to).
When not using this information the call of a selector can happen much faster!
My favourite selector actually is the one of papyrus, but it only works in
papyrus (yet?) [ Stefan says: It's my favourite too ;-) ]
11.7 About dialogs
This subtopic is quite off topic to this FAQ, but I think it fits here.
Take it as a note by me about Tim Oren [22]
I was quite curious about why I like papyrus' font selector much more than
XUFSL. This one does include all features offered by the new libraries.
*And* it doesn't break any design rule I've read.
So I'll try to write, what's disturbing me intuitively [hrrrgn, note by
Stef] And that's not about font selectors but about dialogs in common - but
fixed to a concrete example ...
The popups (with sliders) are, what's disturbing me most.
State-of-the-art user interfaces (Gerd writes "Benutzeroberflaechen", but
in German it's "Benutzungsoberflaechen", the first is the user's skin <g>)
offer selection instead of input (like those *S&" MS-DOS programs). To make
this possible, the selectable thing have to be visible at first sight.
Popups surely can't show everything. And if there are more of'em it's
impossible to take a short look, but one has to take a deeper check what's
available too. Plus one more mouse click to open the popup.
For the theory: Popups are modal parts in non modal (or worse: in modal)
dialogs and modal dialogs are quite interrupting (not only to the user!)
Popups don't fit to the ideas of intuitive user interfaces. I know you're
proud of using Popups (even with sliders) but please: don't use them if
possible.
(Note by stef: file selectors are soon not out of concurrence, there's a
new - non modal - one, released early '95! Looks nice, I recently got it.
FREEDOM 1.0 beta;
Note by Gerd: It uses a different mechanism than described above; it
needs an additional process)
12 Distribution
12.1 Atari
The drivers named with Atari are availabel from Atari. Send three disks,
Money for shipping and a letter to them and you'll get them with printer
drivers and fonts.
This Package is available at Atari shops too.
No docs but for this price ...
(That's the way in Germany - other countrys may differ!)
12.2 BELA
The fonts named BELA were available from BELA
There were two disks with packed printer drivers and fonts for them.
The fonts DO have the same IDs like the ones from Atari, but the internal
font NAME is different. Due to this these fonts are correctly not accepted
by some programs if used with Atari fonts.
There's almost no documentation. Not even a hint about the one owning the
copyright for the drivers or about the author(s)
One last thing about BELA: R.I.P. ;-)
12.3 Language
The driver named Language is spread on the language disc of the MegSTE
12.4 Internet
The drivers signed with 'I' are to be found in the Internet.
For example: ftp.cs.tu-berlin.de
12.5 Working Title
The WT drivers are spread with Calligrapher. They are (c)Working Title, the
wt driver are licensed by Working Title.
No drivers are on the Calligrapher DEMO-disc. The drivers coming with
Calligrapher-lite (15DM) are signed with CL in the tables.
Screen fonts are on both discs.
12.6 XWindow System
There are PD Speedo fonts from Bitstream. These can be used with Speedo 4.2.
I (Gerd) have no problem using them (even the umlauts are correct)
To find them let Archie (see 11.12 FTP) search as follows:
set search sub

12.7 COMPO
COMPO offer two Bitstream Speedo packets with 100 fonts each. One costs
DM99.-
(At your own risk)
Since some time COMPO also offers a CD-ROM with TrueType and Type1 fonts/faces.
These seem to be the same ones as on the StarType CD, but TrueType and Type1
on a single CD-ROM.
The price is DM99.-
12.8 IMG-0300
In the Internet:
ftp.uni-muenster.de /pub/atari/Gdos
12.9 Others
I don't make a choice of drivers. The limit is all of them. The authors (and
users) of the programs are asked now to write me, which GDOS drivers come
with the programs (With information of: Codelenght, Date and known bugs).
11.10 FTP
Many students can get software worldwide via ftp. Prices for steady
connections are constant, but connections between America and Europe
have to be paid depending to the volume of data transferred.
Please try not to ftp across the big blue and use short ways.
Use transferring times not in the range of working at the server!
('9 to 5')
Files with known names can be found by Archie.
In Germany:
telnet archie.th-darmstadt.de
login: archie
help
In the US e.g.:
archie.ans.net
Archie will automatically display other archies. use the one thats' closest
to you.
The Archie databases ask about once each month one ftp server after the
other for freely available files
One more small hint: atari.archive.umich.edu ist always totally busy. Not
even mirroring to other servers helps.
Better connect to
- amiga.archive.umich.edu
and type cd atari from there.
This computers have the same HD mounted. BUT: First search your own vicinity!
12.11 SciLab
SciLab's GDOS drivers are not mentioned in the driver's tables though they
are very favourite - specially the colour drivers.
These drivers no langer can be ordered without a program. This is due to the
programs that lots of programs have when using the colour drivers. SciLab
would be blamed then.
You only can get these drivers by ordering a program from SciLab or making
the distributor (of the software you use) licensing those drivers. SciLab
always has 'an open ear' for that. Those are especially the Speedo capable
drivers for HP 600dpi and HP 500C/550C. Actually these are distributed with
Speedo 5 too.
12.12 Star Division
Star Division sells two CD-ROMs (StarType) with 500 TrueType/Type1 fonts/
faces. These are mostly complete packages of fonts.
One example:
Zapf Humanist 601 is available as:
o roman
o italic
o bold
o bold italic
o demi
o demi italic
o ultra
o ultra italic
A lot of Bitstream fonts are included. (e.g. Zapf Humanist 601 as noted above)
There are two ITC faces too. In Germany these two CDs are (at least)
available for DM69.- from Vobis. A booklet with a short overview is available
there too.
13 GDOS versions
13.1 The ones from the bones
Atari-GDOS, AMCGDOS, ABCGDOS, NVDI and possibly G+Plus use the same drivers.
13.1.1 Atari-GDOS and AMCGDOS
The Atari-GDOS is the father of each GDOS coming after it. It's most
remarkable character are lots of bugs and it's horrible slow speed. But
that's history.
AMCGDOS is faster and has less bugs. But it almost has the same capabilities
and was distributed together with Atari-GDOS. (stef: This one works with the
pre-release of MagiCMac!)
13.1.2 ABCGDOS
Comes from The Netherlands (I think so) and is almost totally unknown. I
only mentioned it because it's a GDOS.
13.1.3 G+Plus
Does anyone know anything about it?
13.2 One step forward
Even though there was a very good GDOS in NVDI, Atari had an open ear to the
request of users and coders and tried to raise the capabilities of GDOS.
13.2.1 FontGDOS 2.0
This is a GDOS still using bitmap fonts. It uses own drivers.
The drivers from this package are really much faster than the former ones.
(Only bitmap fonts and graphics are comparable of course)
I didn't have any problem using these with other GDOS versions but you must
limit to the old fonts.
FontGDOS is the follower of the Atari GDOS. Mainly it differs with the
Bezier function and faster (and color-able) drivers. It's got nothing to do
with FSM-GDOS or SpeedoGDOS.
FontGDOS is availabel from several firms which use it for their programs.
13.2.2 FSMGDOS 3.0
During the development of FontGDOS, Atari created a GDOS that can handle
vector fonts (named OTL in this FAQ). So FSMGDOS isn't a follower of FontGDOS,
but was developed the same time. FSMGOS practically was ready to be released
but due to massive protest by the developers it was cancelled in the last
moment. Except to bundles it never has been distributed officially.
13.3 Actual developments
13.3.1 SpeedoGDOS 4.0 and 4.1
See [5]
The information if it's a Speedo or bitmap font can be found in byte 33 of
the Fontname (vqt_name, INQUIRE FACE NAME AND INDEX, VDI 130). zero means
bitmap font and one means FSM- or Speedo font.
Some Problems are inportant to be mentioned:
A coder can't find out if a driver can handle Speedo fonts (see last
question in 10.3)
Some font IDs are used by bitmap AND Speedo fonts, though different fonts
with similar IDs may never be installed the same time.
If you don't take care of this you'll get bombs.
It depends to the user to install the right drivers and fonts. The coder
can't help here to stop errors.
The best way is only to install bitmap fonts with the right drivers or to
use a Speedo only system.
The monospace font coming with SpeedoGDOS 4.0 has no umlauts (ae, oe, ue ...)
For installation and coding best is to refer to [6-8]
Remember starting NVDI before SpeedoGDOS in the AUTO-Folder!
The ones that bought Speedo got 4.0, the Falcon buyers got 4.1
13.3.2 Speedo 4.2
Let's see, what Ulli Ramps has to say:
Huhu! [TM]
The following is a list of changes made to SpeedoGDOS.
1) Line-A - Due to many requests from developers, SpeedoGDOS is now no
longer Line-A dependent. All output is done through VDI calls. This
was done to make Speedo compatible with various graphics cards, and to
make it more multi-tasking-friendly. In addition, users should be
able to use various VDI replacements with GDOS.
Another benefit from removing the Line-A dependency is that we no lon-
ger have to worry about the scratch buffer used for algorithmic spe-
cial effects. We have implemented the special effects inside of Spee-
doGDOS and the drivers, so that the user/program does not have to wor-
ry about the memory needed to accomodate arbitrary sized characters.
Unfortunately, this means that old drivers need to be relinked with
the new independent library (found in the new driver kit).
There are plusses and minuses of the new implementation of special
effects. In many cases, the special effects will be slower. With
all previous incarnations of GDOS, you could not use 'bolding' or
'skewing' at non-90 degree rotations; now both of these work at all
rotations. On the other hand, 'lightening' used to work at all angles
and combinations of effects; now 'bold' mixed with 'lighten' only work
at 90 degree rotation angles.
Miscellaneous Note - When using special effects, many applications
have a hard time placing the cursor. In both the v_gtext() call and
the v_ftext() call, the only cursor compensation to be made is for
bolding. Bolding adds the thicken value to the number of pixels of
each character. For rotated characters, note that the extra pixels
can be considered a vector along the positive x-axis which is rotated
at the same angle as the text and added to the advance vector; there-
fore, the length of the text string should remain the same at any ang-
le. This is true even when SpeedoGDOS generates characters on a scan-
line basis (when the character does not fit in the character cache),
although it does not implement the special effects. Also, applica-
tions should watch for the case when they keep track of the cursor
position with vqt_advance() or vqt_width(), instead of vqt_extent() or
vqt_f_extent(). In versions prior to 4.2, the application could accu-
rately place the cursor by adding two pixels for every outline charac-
ter and by adding left and right skew offsets for a skewed string.
Now these effects are generated by the outline font engine, so the
application must either rely on the extent calls or it must inquire
for the advance vectors for characters that are skewed and/or outlined
separately. For compatibility purposes, it is recommended that the
version number of SpeedoGDOS is checked so that programs can handle
both old and new characteristics.
2) Font ID's - Speedo font id's have been promoted to a higher range
of ID numbers. This was introduced to avoid conflicts with bitmap
fonts and more importantly, with the system font (which conflicted
with a variation of Swiss 721). For those applications which use the
usual interface with Speedo (i.e. use vqt_name() to find out what the
font ID's are), there should be no problem, except if documents have
font ID's embedded into formatting information. Of course, all the
user has to do is substitute the font. If the application actually
goes into the font file header to read the ID, note that we are adding
5000(decimal) to all Speedo font ID's.
3) Printer Driver Incompatibilities - Speedo will now check the prin-
ter driver it is trying to load for the '_FSM_HDR' cookie embedded in
the driver header information. If GDOS does not find the cookie, it
will not allow the loading of any fonts; therefore, you can still use
your driver for non-text applications. For future reference, please
be sure that the driver header begins on a word boundary for all dri-
vers to be used with this version and any future versions of GDOS.
4) Vst_load_fonts() - We have made two optimizations to the loading of
fonts. The first is when a load_font call is made, GDOS checks the
date of the extend.sys file to see if it was modified since the last
load. A reload used to be mandatory because a bigger scratch buffer
might have been required. Since we no longer need a scratch buffer,
GDOS only checks to see if a change has been made to the list.
The second change is that GDOS no longer deallocates the global list
of fonts if there are no more workstations using GDOS fonts. There-
fore, application launches will be faster. On the other hand, the
miscellaneous cache never gets cleared of font header information,
unless a reboot happens.
5) Memory.sys - The memory driver used to mistakenly open a printer
handle.
6) vst_height() - Vst_height used to have a bug in which a maximum
point size is reached and then the size begins to shrink. This is
fixed.
7) Postscript table - The Postscript table has been fixed (i.e. the
indexes were off by 32 for certain Postscript files).
8) Fixed vrt_copyfm() in the drivers.
9) When in 'bicsmode', character 0 was not passed through to the font
engine.
10) Negative point and set sizes - The handling of negative point and
set sizes has been made consistent with the original handling in
FSMGDOS.
11) The handling of fractional setsizes was incorrect in the drivers,
and is now fixed.
12) V_ftext() in the drivers can now handle the offsets passed into
the ptsin array.
13) Screen drivers can now safely load as device 10.
14) The memory driver can be loaded residently.
15) vqt_devinfo() - Vqt_devinfo() now returns information, whether or
not the device has been opened. Furthermore, the device drivers name,
found in the driver header, is copied into the ptsout array; the name
is 26 bytes long. Note: if the driver is not SpeedoGDOS-compatible, a
null string is returned, and if there is an error, a -1 is returned in
ptsout[1].
16) vst_width() - A new call has been added to Speedo. The call is
similar to vst_height() except that it sets the width. The bindings
are identical except that the opcode is 231. Note: As with
vst_arbpt() and vst_setsize(), you must call the general call (i.e.
vst_arbpt() or vst_height()) before using the width calls (i.e.
vst_setsize() and vst_width()). In addition, the general calls always
reset the widths.
Miscellaneous Note: Although these have been published before, many
requests have come in for the SpeedoGDOS error codes. Here they are:
Code 1 Out of memory
2 File open
3 File read
4 File write
5 Speedo engine error
6 Character too large (not used, defaults to line output)
7 No room for scratch buffer
8 Character cache error
255 Miscellaneous
These errors are placed in the error code address that applications
should provide. Note that if you have MultiTOS installed, GDOS will
report the error to Salert, the system alert box. A revision of the
error handling is overdue, since some of the errors are no longer re-
levant (e.g. code 6), and error code 5 is returned for the lack of
availability for pair and track kerning (in addition to the serious
errors).
Well, again a big thank you to Ulli!
Now it's me again:
The Installation program for Speedo 4.2 had a small bug yet. If a NEC P
printer is selected, NEC_P.SYS ist written into ASSIGN.SYS. But the
distributed driver hat NECP.SYS as filename. R.O.M. fixed that.
13.3.3 Speedo 5.0
SpeedoGDOS 5.0 was developed by COMPO/no!software using the sources by
Atari.
More than Speedo 4.x it can scale TrueType and Type 1 (see 7.2). Price:
DM129.-
(at your own risc)
Now 9 printer drivers are included - the additional ones. Speedo 5.0 is an
upgrade, so you have the other drivers. But: Which are the old divers? The
ones before Speedo 4.1 don't work (and only falcon users have 4.1; the ones
who bought Speedo from COMPO in the beginning only got 4.0)
So I at once printed a text using Speedo 5.0, NECP.SYS (Speedo 4.2) and
ProList. And? Surprise! It works. That's really astounding because ProList
and my own program (see 2) had problems with this driver and Speedo 4.2.
Using the drivers of Speedo 4.0 at least shouldn't work due to the changed
jobs of Speedo 4.2 and the drivers.
(Could anyone test Speedo 4.1 drivers with Speedo 5.0? I don't quite believe
this works)
Here's how I think an upgrade works (be careful satire)
===================
User: Dear Mr. Compo [...] but my Speedo 4.0 drivers don't work any more.
COMPO: ... best wishes to your decision ... BUT: Speedo 4.2 isn't an
official release. It's especially made for papyrus and not useful
for other programs. On the other hand...though...seen from a
different point...maybe...possibly...Finally you need the drivers
from Speedo 4.2. But we don't distribute them. Ask R.O.M. about
it ...
[later]
USER: Dear Mr. R.O.M., ...I'd like to get a downgrade, free of course.
R.O.M.: ...don't work...our own costs...bla...etc...better wait for NVDI
3.0, we certainly can put you on the list.
User: "S$&"S$/(!S&!^#
====================
Well, *I'm* full of anticipation how users that only had Speedo 4.0 will be
able to make printouts.
Versions of Speedo 5.0 until now:
5.0a (Aug. 3rd 1994)
First release
5.0b (Aug. 8th 1994)
From now T1 & TT font loading works faster.
Known Bug: After calling vqt_headerinfo() the files arent' closed again.
Whe using programs making this with all fonts there maybe can be no more
filehandles (the amount of them differs from one TOS release to another).
Since Speedo 4.2 the 'outlined' attribute only works in special conditions.
It depends on the font used, the SpeedoGDOS version, the point size ... and
which Mantra's are mumbled at full moon.
5.0c (Aug. ? 1994)
From here LOWMEM=0 works like noted in the manual.
Now LOWMEM=0 works as stated in the manual.
13.3.4 NVDI up to V2.51
These releases were made of very fast screen drivers and a very fast GDOS.
Compared to Atari-GDOS, NVDI had almost no bugs. But there functions weren't
almost any more functions.
13.3.5 NVDI 3.0
From 3.0 NVDI is capable of scaling Speedo and TrueType fonts. Different
from SpeedoGDOS it can't scale Type1. The Behne brothers (correctly!) say
this format has least capabilities and only would blow up NVDI. But lots of
special fonts are only available as Type1 and I could use some of them. A
(by principle very good) conversion of the formats is possible but very
difficulty (see chapter 7.4) and no Atari program doing this exists yet. So
the Behne's decision has advantages and flaws.
NVDI's printer drivers are found in 5.7.3
13.4 Comments
Users and coders should be happy with the speed of development. Even the
numbers of font format included in the programs doesn't have anything
comparable on any other platform.
The time between the releases of SpeedoGDOS 5.0a to 5.0c - making one think
there wasn't much of betatesting - doesn't satisfy a lot but, on the other
hand it's nice to see that the competition by NVDI 3.0 makes the developers
hurry.
SpeedoGDOS 5.0 creates problems in some applications that worked perfectly
with Speedo 4.x. This may be due to the negative handles that 5.0 uses for
the new formats. That's not a bug, because one shouldn't calculate with
handles. But some apps do it though.
For coders the manuals coming with SpeedoGDOS 5 and NVDI 3 are only a bad
joke. Even simple user's questions aren't answered:
TrueType (and Type1 with SpeedoGDOS) are handled. But these fonts are
created in platform specific formats. Which ones are handled and what files
with what extensions are needed? Without this information both programs
aren't very useful.
Here some more differences between NVDI 3 and SpeedoGDOS 5. Get your own
clues.
o The driver's concept
A real plus for NVDI 3. They're small, fast and
easy to be configured by the user. But they're not able to print with
colours yet! And setups aren't to be copied, due to everything set in
one file.
o Print to files
NVDI drivers can print in a file and the program won't
notice this (SpeedoGDOS can't)
o Need of RAM. NVDI 3 needs about as much RAM as SpeedoGDOS 5 and NVDI
2.5
o Installation
NVDI 3 is begginer-friendly to install BUT: Everything
having the same name as a file to be saved is overwritten without any
request to the user: META.SYS and the old Screen drivers. This makes
different configurations for testing quite difficulty.
o VDI Speed
NVDI 3 is faster than SpeedoGDOS 5 and NVDI 2.5, which is
much faster than SpeedoGDOS 5 without NVDI. But SpeedoGDOS 5 and
NVDI 3 can be enough.
o Bugs
Current changes here. I don't know, who actually has more bugs.
o Support
Compared to SpeedoGDOS 4.2, NVDI had a big plus here up to
Version 2.5. Since NVDI 3 and SpeedoGDOS 5 me and others don't get
answered by the Behnes but no|Software is quite active in public.
I guess after the hard work with updating (stef: They were busy with
updating/selling NVDI at the proTOS fair all day long) the brothers
will have more time for support.
o Number of font formats
Only SpeedoGDOS has Type1 capability. Some of those fonts are very
expensive, but there are special fonts not available in other formats.
14 Source
Being a developer it's possible to get an almost complete printer driver in
object code. This one only must be adapted to the special printer.
This package is available for GDOS and SpeedoGDOS.
15 Tips'n tricks for users
15.1 Pixel trash at printing
Printing graphics on a NEC P6+ (maybe other printers too) including a lot of
black in a line I often had the problem that one line was left out (Speedo-
drivers NB15, NECP) or two lines were printed displaced in one line (Speedo-
drivers FX80, NX1000).
This happens when printing directly and via CENSPEED. When using VARSPOOL
this effect is gone.
VARSPOOL can be found on the driver disk of the NEC-printers.
15.2 NEC P6+
Once in a while a NEC P6+ will get noisy (rrrrrrrrrrraattatatattaa).
When You open the front you'll see a round stick (about 1cm thick).
Put two drops of sewing machine oil on it each year (you'll get it from
Mom)
15.3 Overwritten Speedo faces
Sometimes Speedo writes in face files producing interesting effects. To fix
this I have a second order besides GEMSYS filled with the Speedo faces on my
harddisk. If I get strange effects again I copy these files to the GEMSYS
folder. The almost fixes it in most cases.
15.4 SpeedoGDOS & MagiC! (VT52.PRG)
Andreas M. Koepfer:
SpeedoGDOS 4.1, 4.2, 5.0b used together with MagiC! (former Mag!X) have a
problem. When VT52.PRG has to be used it already has to be in memory to
correctly start a TTP (or TOS??). Otherwise VT52.PRG scans the fonts, what
takes longer than the time it has been given for that. Putting VT52.PRG
into the APPS folder of MagiC! is a workaround for that. Then the booting
takes longer, but no errors occur. *But* a lot of memory ist lost. I wrote
Andreas Kromke - who sent the upper note about the timeout. I guess the new
MagiC! release will have this flaw fixed.
16 Tips'n tricks for coders
16.1 Fontsize and Pixelsize
Here are my experiences with GDOS and WYSIWYG. Credits to Ulrich Rossgoderer
for confirming these.
It's about the output of vector graphics and text on screen and printer.
The size of text is defined in point and is always the same - independent
from the resolution of the output device.
Different are vector graphics: they have to be recalculated in pixels before
the output. Should be no problem because when opening a virtual/physical
workstation You get the pixel size in micrometers in devParm[3] and
devParm[4].
Let's assume the vector graphic is saved internally in micrometers, then the
definition points at the output simply have to be divided by devParm[3] or
devParm[4] to get the position in pixels. When doing the output in windows
an offset has to be added. but thats not relevant here.
So far for the theory being quite simple so to this point (see [3]).
Now for the practice.
As described above we output a text and a border - saved internally as
vector graphic. It doesn't matter here if the text is a Speedo or bitmap font.
To have a better chance to compare the border exactly surrounds the text.
Doing this I got the following experineces: The text exactly filling the
border on the screen (ST-high) is - when printed - much too small compared
to the border.
An error in the recalculation of the pixelsize can't be the problem, because
I made the printing with the drivers NB15, NECP, FX80, NX1000 and the results
are the same.
I have only one explanation for this: The screen driver supposes a different
resolution for the pixel size than for the font size.
Two solutions I can offer:
First you can use another pixel size on the screen than the one given from
the operating system. After opening the virtual workstation (and ONLY
this one!) I calculated
devParm[3] := 282
devParm[4] := 282
and with this parameter I made the recalculation from micrometers in pixels.
Now the relation from graphic to text on screen and print-out is exactly
the same. But now a DIN A4 page doesn't fit on the screen in it's width.
The numbers are found by me the experimental way and possibly can be
optimised
Another solution may be this: Use a smaller font size for the screen (and
ONLY there!) by multiplicating the size with 72/96. This is simple with
Speedo fonts because the size in points can be defined by almost endless
values behind the point. Using bitmap fonts this won't work due to not
having a screen font in the 72/96ish size for every printer font. (Different
to translate this, sorry - SD)
This method surely is to be midified for ST-Mid and other resolutions.
From Wilfried Behne (Half NVDI ...) SpeedoGDOS ignores the devParm[3]
and [4] - values of the screen drivers. The values of physical workstations
ARE taken.
16.2 Selecting drivers
When testing several GDOS programs I found out, that some coders have
problems
with the following reasons:
Users can freely assign drivers in the ASSIGN.SYS.
There may be a setup like
23 FX80.SYS
27 NECP.SYS
28 NB15.SYS
31 META.SYS
61 MEMORY.SYS
How may a coder find out which drivers are installed (and ready)? Even
though
there's no Printer 21?
Quite easy: When the program supports printers ALL drivers from 21 to 30 are
to
be opened and closed again at once. An installed driver gives back a
devicehandle >0 when being opened. vf_devinfo gives back correct values when
a driver is opened.
Do the same thing with drivers 61 to 70 when MEMORY drivers are supported.
The ASSIGN.SYS as printed above is very useful. That's because the NEC P
printers support all these drivers and print in different resolutions.
16.3 The Metafile (MF) format
If been asked to count, what i don't know about Metafiles 8-)))
By the idea the Metafile format is quite simple. It's a recording of VDI
calls (including parameters) made by a program.
A program making it's output via GDOS will open a Metafile driver instead
of a printer driver (see 5.7) and the output will get there just like to a
printer.
A Metafile reading program recreates this recording.
But the simplicity of this format is one of the biggest problems of
metafiles because different GDOS releases exist and different drivers
with different capabilities. So, one programs makes output being understood
by the GDOS actually installed. When this Metafile is read by a program
running under a different GDOS with less or different capabilities, how
can the recording be recreated?
Concrete examples:
The length of ptsin and intin fields is limited (different for different
drivers) usually. The Metafile driver can handle this in another way.
This can have influence to text output, poly line & marker, filled area
and more ...
Next problem:
A font face not available on the output system is used. I which way another
(most similar) face has to be requested by the program making the output?
At this point, this is a problem to be handled by the coders of the
reading graphics programs (who willknow, what they're doing).
But when writing a metafile header you have to know, what you're doing. I
don't but I'll give it a try ;-)
The resolution set for a metafile is a decision of the application. If
there's no resolution set, 300dpi are used. That's a pixel width of 0.085mm
(Stef: that's not a pentium calculation, but *where* are 300dpi equal to 85
micrometers? On a 72dpi SM124?
Gerd: everywhere)
Screen drivers are only capable of handling raster coordinates. For
metafile output the same routines are used, so I'll limit the next info to
raster coordinates (even though metafile can handle NDC's). Those
coordinates are defined from upper left to lower right.
To define a system of coordinates, metafile do this:
o (W)idth and (H)eight are set in millimeters (mm) via vm_pagesize.
That's the (positive) difference beetween the lower right and upper
left corner (which doesn't have to be in the origin)
o The rectangle (xmin, ymin, xmax and ymax) is defined in pixels via
vm_coords. The way to calculate this rect. is found below.
o Here inside another rectangle is defined in pixels via v_meta_extents.
It's got nothing to do with the system, the MF reading application
get's info how to clip (what doesn't *have* to be done!)
Note: papyrus doesn't clip; kandinsky does, but it moves the graphic
to the lower right a bit making miss a bit of it on the screen.
So it could be useful to set the size for v_meta_extents a bit
larger than the one for vm_coords.
This way the system of coordinates, the resolution (width and height of a
system) has a fixed definition.
But the veriables set aren't the ones an application usually calculates
with.
Here's an example what's to do, when the application knows the resolution
wished (in dpi), the upper left (X1,Y1) and the lower right dot in tenths
of a millimeter (or a multiple of it).
Here's how to get the width and height of a pixel by the resolution:
25400
(Pixel height in tenths of a millimeter) = --------------------
vertical res. in dpi
25400
(Pixel width in tenths of a millimeter) = ----------------------
horizontal res. in dpi
(W)idth and (H)eight (in millimeters) are needed for vm_pagesize:
W = (X2 - X1 + 1) * (Pixelwidth in tenths of a millimeter)
H = (Y2 - X1 + 1) * (Pixelheight in ...)
xmin, ymin, xmax and ymax (in pixels) are needed for vm_coords:
X1
xmin= --------------------
Pixelwidth in 1/10mm
Y1
ymin= ---------------------
Pixelheight in 1/10mm
X2
xmax= --------------------
Pixelwidth in 1/10mm
Y2
ymax= ---------------------
Pixelheight in 1/10mm
v_meta_extents is found the same way as vm_coords. To make Kandinsky
display everything, xmin & ymin can be set smaller and xmax & ymax larger.
Before making any output into a MF, first set the system of coordinates.
(In the early past I noticed, that my desriptions are that good, that even
I understood them <g> [Stef:I hope the translation is that good too])
Further informations:
Ulrich Rossgoderer coordinates a list of further informations to put
in a MF via v_write_meta (See version 2.4 of this FAQ). The Profibuch [2]
the Atari Compendium [3] and the standard book "Ueber FIleformate [20]
contain further information. And every literature about VDI calls is helpful,
too.

18.1.2 Critics to the translator
Hi, this is Stefan writing :-)
The reason why I wrote this translation I can't find in my head ...
Guess it's because Atarians should work together and support each other!
Well, if you wonder about some errors of spelling or syntax remind this:
I learned English at school for 4 years and after that I kept my knowledge
actual by playing some text adventures and now by reading cs.atari.st and
cs.st.tech and some of the ANet groups
If you find some errors in this translation, please don't send them to Gerd
but
to me:
cookie@cookie.syd.de
Referring to the feedback on this translation there seems to be ANY error in
it.
I didn't get too much email now - and no postcard, so I'll set my address
here too: Stefan Damerau
