Graphics in Ada

Graphics in Ada

[Oliver Mullarney]

I've been out of the Ada world for a while, and am curious as to the status
of GKS, which I used extensively when I worked with Ada. As I recall, GKS
was adopted as the 'official' graphics system for Ada, the main reson being
portability.

Has anything else (Phigs, X etc.) usurped GKS? Does anyone actually use it,
or does everyone doing graphics work write a binding to the native graphics
system for the hardware platform of choice?

Graphics in ada

[Dr Snow]

hi,
	I was wondering how well ada could handel displaying graphics..

eg..
	small logo,
	large text
	small text
	boxes filled and empty.
	and different colours..
	in different windows or pages

	and which version of ada is best for writing this sorta stuff in ?

Thanks in advance

>I was wondering how well Ada could handle displaying graphics.
There's Ada source code using VESA PC graphics on Compuserve,
IBMPRO forum, VESA library in both VESTGA.ZIP and VESDM1.ZIP.
Of course if you just want to display the things Windows has
APIs for, you need merely make the relevant Windows call.  You
haven't mentioned what hardware, OS, or compiler platforms your
questions pertain to.

basically I am looking to write the program on a ms-dos level then later
produce an x-windows or pc-windows.. 

So at the moment I wat info about ada on a msdos system to produce graphics.

I assume that when you talk about graphics programming in Ada you mean
that you're going to either use X Windows or a vendor (machine)-specific
graphics package. In either case, you need a binding to that package. If
it's a vendor-specific graphics package you're dealing with, you need to
talk to the vendor. In the case of X Windows, there are several X
Windows bindings packages. I believe that there is at least one
available through ASSET. Also, the Software Engineering Research
Corporation (I think that's what SERC stands for) has an Ada/Motif
bindings package. I use it and I think it's pretty good.

Graphics in Ada

[d97sund]

Hi!

I wonder what you do if you want to make graphical applications in Ada. Can
you use Ada to make advanced graphical applications? How do I do such simple
things as draw a line and draw a circle for instance? I'm interested in
everything from simple graphics to advanced graphics.

Thank you!

If you are using Claw to run with MS Windows you might choose:
    procedure Line_to(Easel : in Claw.Root_Canvas_Type'Class;
                      Pos   : in Claw.Point_Type);
        -- Draws a line from the current position to Pos with the
        -- current pen.
        -- Raises:
        --      Not_Valid_Error if the canvas object is not valid.
        --      Windows_Error if Windows generates an error.

    procedure Ellipse(Easel : in Claw.Root_Canvas_Type'Class;
                      Rect  : in Claw.Rectangle_Type);
        -- Draws an Ellipse inside of Rect with the current pen,
        -- and filling the interior with the current brush.
        -- Raises:
        --      Not_Valid_Error if the canvas object is not valid.
        --      Windows_Error if Windows generates an error.
If you are running the control systems of a 737 and trying to use
it as a skywriter, I suppose you need to set the control surfaces
differently for straight lines, loops, and circles, but I don't
know the Ada calls in that environment.  (Perhaps you could wait
for Windows CE controlled airliners and then use Claw? #.#)
  What environment did you have in mind?

To do graphics in Ada you actually do the same as using C or C++. Usually
you use a library. Currently there are both native Ada graphics libraries
and bindings to other graphics libraries available on all sorts of platforms 
and for most -if not all- Ada compilers

If you need help locating them you should specify which Operating System
and Compiler you are using.

Success,

For Win95/NT you can use an OpenGL binding. 
It is part of the Win32Ada binding and runs with GNAT and ObjectAda.

My company has developped a full Ada 83 implementation of Xlib Xt 
and Motif libraries. This is called XInAda.
Callbacks are implemented through generic instantiations.
You may use TeleUSE or Uim/X to develop your application.
XInAda is supported on most native (and some others) development 
environments.
We also have a full Ada95 implementation that takes a real

sure.  pick the GTK+ binding to Ada.

see my home page for pointer to the GTK+ binding. (search got GTK)

also there is TASH (Ada binding to TCL/TK) for doing graphics.

There are for Windows (adagraph), Linux, bindings to OpenGL, X-window,...

In "my" area (GNAT/DOS - 32-bit DPMI):

vgapck07 - basic VGA
svga02   - basic SVGA - very "pro"; detects linear VESA 2 but uses VESA 1.x as well,
           drawing in buffers, fast, reliable! 
graph    - multi-device layer (-> slower) for SVGA, VGA, PostScript, EPSF, DXF;
           pixel coordinates & floating-point definable areas, vectorial fonts,
           supersets Borland/Turbo Pascal's version,... and not fully complete

The 3 come with complete sources.
The 2 first come with ez2load gnat/dos pack;
for the last one see my "software" page...

I've used Ada/Tk and it works pretty well.  You do have to learn Tk if

Does that mean something different than Martin Carlisle's AdaGIDE and
the Windows bindings available with 3.10?  
  I think I remember when installing 3.11 that it says it's illegal to
use the Windows bindings unless you have permission from Microsoft,
and I don't seem to find rc.exe, which of course is required to use
Windows Resource files.  Do the docs suggest people just download the
free ObjectAda compiler to get the permissions and the resource
capabilities?  Did I miss something? 

Graphics in ADA

[William E. Huttemann Jr.]

Does anyone know how to implement VGA graphics in ADA? I am a new ADA
programmer and I am learning from a book by John English called "ada 95 -
The craft of object oriented programming". The book states nothing about
graphics programming. I'm assuming you have to write your own packages to
access the graphics memory of the computer. But, alas, I also cannot find
any information on how to access memory locations in ADA. One last thing -
according to information I've read concerning ADA, it's possible to
interface with other languages (such as C) and make use of their libraries.
Is this correct? Any information would be appreciated.

You need an address representation clause, eg,
  CRT : array(0 .. 479, 0 .. 639) of Pixels;
  for CRT'address use (segment=>16#A000#, offset=>0);
(This address clause is from memory for 16 bit DOS, Other OSes have
different memory structures, of course.)  There's also the little
matter of doing IO operations to the graphics card, which will involve
calling something like Output(Port=>16#3F8#, Value=>16#81#), depending
on what your compiler vendor has supplied in the library, or doing
calls to the BIOS, again dependent on your vendor supplied library.
If you actually need 16 bit DOS routines, and have access to
Compuserve (now part of AOL), look in the VESA section - there's a
(very old) Ada 83 driver and example programs.  If you are running on
Windows, the whole style of graphics is different.

Unfortunately this is very system dependent (and I wouldn't like to be
parochial and risk offending Mike Feldman by describing PC graphics in
excruciating detail ;-), and I don't think you'll find any Ada book that
will tell you anything specific about graphics programming.  As the book
was already hitting the 500 page mark I left out anything vaguely system
dependent, as noted in chapter 20: in this case representation clauses
and packages like System and Interfaces.C.  

Since you talk about "VGA graphics", would I be correct in assuming
you're talking about MS-DOS? If so, try this URL:

  http://burks.bton.ac.uk/burks/software/libs/

In this lot is a copy of vgapck05.zip, which is a copy of Jerry van
Dijk's VGA package for MS-DOS, and svga01.zip, his SVGA package.

Yes. :-)

More helpful:

1) VGA graphics usually mean using DOS. If you are using the GNAT compiler
   on DOS, it comes with both a standard VGA graphics packages and a
   SVGA (VESA/VBE) based package.

2) If you are using a form of windows, AdaGraph is quite easy to use for
   basic graphics. It is available for both GNAT and ObjectAda.

3) If you are using Linux, there is a package for using vgalib from Ada.
   A X-based version of AdaGraph is underway.

All of the above can be found on my homepage.

Alternatives are to use a binding to one of the many portable graphics
libraries such as Gtk, Tcl/Tk, OpenGl/Mesa with GLUT, etc. However, as
a beginner I would advice using one of the easier to use native packages.

There's also adagraph and jewl for windows.  GWindows supports drawing

Note that this was always somewhat of false statement since you could always
bind to other
languages. It may not have always been easy but it was always possible.

Re: graphics in ada

[Marin David Condic]

Given that Ada - like most programming languages - is capable of 
generating any permutation of bits in memory that you'd care to imagine, 
how is it "not possible" to do graphics in Ada?

If the question is "Does Ada have a built-in graphics library of some 
sort?" then the answer is "No, there is no standard graphics library..." 
  But you probably could find some non-standard graphics libraries out 
there in Ada or interface to other libraries provided on your machine. 
(The latter being a lousy answer.) So I guess basically its a case of 
"Roll Your Own" or go with some language that has it built-in.

  I guess the video editor I built in DOS with Ada 83 in 1992 must
have not been possible.  Or the teleprompter that I posted on Compuserve.
Sigh.

I would say that either your professor was not educated in computer science,
or (more likely) you misinterpreted his answer.  Perhaps the Ada
installation you had on your computer system did not provide graphics
library interfaces for Ada, but this does not mean it is not possible to do
so.

Ada 95 makes life much easier since provision is included for interfacing
with libraries written in or for other programming languages.

I wrote packages to do graphics under DOS in Ada in the late 1980s and 
early 1990s, so either your professor didn't know what he was talking 
about (not uncommon where Ada was concerned) or you misunderstood him. I 
worked on one project in which the SW was developed on a Unix machine 
for a DOS target, and the terminals we used on the Unix machine didn't 
have graphics capabilities, so we were unable to include graphics in the 
SW. The project manager interpreted this as "you can't do graphics in 
Ada," but he was just stupid.

For very simple graphics under Win32, you can use AdaGraph, in addition 
to the other fine libraries mentioned in this thread.

most of the times, things are possible,

I suggest using AdaOpenGL over GtkAda's builtin OpenGL lib with GtkAda though. AdaOpenGL
provides OpenGL 1.4 support and up-to-date OpenGL extensions.
