Please forward suggestions.

Yes,
That is if I understand your question correctly.

If you would like to use X-windows, there is a binding set available
free from DEC (ftp://gatekeeper.dec.com), as well as several others.
If you would like to use a different GUI, all that is needed really
is to build an Ada binding to the normal C(or whatever language) calls
example:
function createTextField(parent : widget;
			 name 	: system.address;--pointer to a string
			) return widget;
  pragma interface(c,createTextField);
  pragma interface_name(createTextField,
			language.c_subp_prefix &  -- The subprocess
						  -- prefix that the
						  -- binder uses
			"createTextField");       -- The internal
						  -- C function name

successful bindings have been produced for X-windows,MS-Windows,
Windows-NT, and many more.

As I have posted often before, producing Ada bindings to C is a subtle
thing.  There's a LOT more to it than Bernie's posting shows.  

For X/MOTIF, you should invest in a commercial product, produced by
people who understand the issues, and are willing to support the
product.

Please note that pragma Interface_Name is a vendor-specific pragma; it's
not part of the Ada 83 language definition.  Consult your documentation
for information on how to do this with whatever compiler you're using.

Ada 95's Annex B provides better mechanisms for interfacing to other
languages.

How would I implement graphics using Ada? I'm looking
for simple lines/points/colors and maybe a routine to display
BMP's or another file format. Where can I find more information
on this?
Thanks,
Aaron

Generally, by calling the same routines you would in C. However, writing C
linkages is not most people's idea of fun, so you may prefer to get one of the
prebuilt GUI packages available. Which one depends on exactly what kind of stuff
you want to do, and what platform you want to do it on.

Here's a minimal package for that:

It seems PBM (Portable Bit Format), formerly NetPBM, is the way to go, at
least on Linux systems.

On Google ;-)

Other folks on this list will direct you to strangely named graphic
libraries like DPPMG (?) and/or bindings to GUI systems like Motif (?) and
of course AdaGraph (?) for Windows (this I have tested and found
slowish) ;-)

   Look at www.adapower.com  There are thin and thick bindings to Windows
(mention of BMP suggests Windows or DOS is the platform here) and SVGA IO
for DOS.

If you look for e.g. BMP-display on windows you could look into
the code on my page www.adapower.com/schroer .
In the package opengl.bitmaps in ogl-src.zip you find source for
reading and displaying BMPs.
You could also look into my mail from the 14-th of may where the
download of all files is described (the page is not 100% correctly
set up till now).

[Necros]

Somebody Knows if some package that allows to load images standard formats 
(gif,jpeg,bmp...).

Which the best graphic package is "Adagraph,Gwindows..." ????

Thanks,

Re: Graphics

[Bruce or Tracy Jacobs]

Check with 

     Stephen Leake <stephen.a.leake.1@gsfc.nasa.gov>

He has Windex package that will read BMP, possibly GIF, too.

(Want to have some fun?  Read the GIF specs and write a program
to read a GIF image.  Been there, done that.  Am trying with JPEG,
but it appears to be even more difficult.)

If it can help, there are GIF and BMP decoder there
  http://www.mysunrise.ch/users/gdm/e3d_html/svga-io__ads.htm

>Which the best graphic package is "Adagraph,Gwindows..." ????

It depends on the direction it should be "best" - speed,
vectorial graphics,...
Of course for the latter I couldn't recommend but this:

If you have the Win32 binding, you can use Win32.Winuser.LoadBitmapFile.
If I remember correctly, it will load all three of the ones you listed.

Ok, thanks...


I'm programming a Concurrency game in Ada95, and i would want to be able 
to generate the initial graphic elements from external program (Paint Shop 
Pro, Corel Draw)... it would only them in virtual memory to begin, and it 
would create miscelenea later with them,,, In language C is easy, in Ada, 
I don't Know for where to begin...

The game is a practice, PCMAN Vs Monsters.

Thanks,

You must mean "using this wizzy graphics package I have that has a C
interface, it is easy".

> in Ada, I don't Know for where to begin...

Write a binding to the wizzy graphics package, and do the same things
you were doing in C.

Then publish the binding, so the rest of us can do the same :).

> The game is a practice, PCMAN Vs Monsters.

I'd like to see that, enough that I'll offer to help. I wrote Windex,
an Ada binding to Win32. If you don't mind being restricted to
Windows, it's a good way to go (see
http://users.erols.com/leakstan/Stephe/Ada/windex.html). I can help
you write the binding to the wizzy graphics package, or just use
Windex straight.

Re: Graphics

Since this is a Windows program. I would suggest converting your graphics in
to BMPs and putting them in to you resources. This way you get one EXE with
everything in it. If size is a factor, you can using UPX to compress your
exe.

GWindows (http://www.adapower.com/gwindows) is currently the best Modified
GPL (ie. Free as in liberty) library available (I wrote it, so I am biased
of course :-)

I am currently working on completing GTK+ bindings that will be integrated
with GWindows that will allow for all the whiz bang stuff that MS has been
pumping about XP's graphics (loading, modifying and savings of most graphic
types, Alpha channels etc.) on Win98/ME/NT/2K/XP).

Any library you would use from C/C++ to load in Gif's, etc. can be used with
Ada also. Take a look at the way I build the thick GWindows bindings, in
particular how each function is bound in the body of the procedure and makes
far more use of the excellent design of Ada's ability to bind to C then thin
bindings do. I would also recommend looking at Windex to get a handle on
thin binding as well.

I'd argue that GTK+ is better in any situation where Unix portability 
may be an issue. That's why there really is no one answer to the 
question of which one is "best".
