AFAICS (from makefile) this is a static lib port.
What about a shared lib ?

Only one question - The demos are listed as AmigaOS, not AmigaOS4 - somewhat misleading.

It's not misleading at all. It runs just fine on AmigaOS. It just happens to require a particular minimum version of AmigaOS. Not my fault if users are not up to date.

Ask again when you guys have actually used the library for what it was intended for. Hint, note the heavy use of C++ templates with compile-time polymorphism...

I have to say I loved the demos, they are looking very promising, but has someone made something usefull with it?

Ciao, Alfred

Tested all the demos, well except those few requiring external files, and I must say I'm impressed. Both with the quality and the speed. An art package based on this lib would simply rock.

I'm impressed too. But with some FX I think a speed improvement is possible, though I'm not sure.

As for the Art package would a nice GUI be enough? I mean all the image processing functions are in the library. So some nice icons linked to the right functions would be great.

If you look at the DEMO page on the AGG homepage there's the Chemical Stretch prog which I would like to see on AOS4.

Right. And on the AGG website, it states the following:

Quote:

When building on AmigaOS 4.0 or higher type...(etc...)

So nothing misleading about that in my eyes.

Please excuse my ignorance, but what exactly is this AGG?

The website says it best:

Quote:

Anti-Grain Geometry (AGG) is an Open Source, free of charge graphic library, written in industrially standard C++. The terms and conditions of use AGG are described on The License page. AGG doesn't depend on any graphic API or technology. Basically, you can think of AGG as of a rendering engine that produces pixel images in memory from some vectorial data. But of course, AGG can do much more than that. The ideas and the philosophy of AGG are:

For the full list of features, see the "about page":

http://www.antigrain.com/about/index.html

In short, it is a very powerful 2D graphic rendering library. It has some very nice capabilities.

I've understood that it compiles easily.

Has anyone tried to use it with AOS3.x?

There's an SVG viewer on the site - which I would love to see integrated into one of our browsers...

A minor update. I've resynced the SDK on os4depot with the one available from the AGG web site Maxim published. They are both identical now except the one on os4depot is compressed with lha.

Remember it's a pure software solution. As such, it's really blazingly fast.

The interesting question would be whether it's possible to use some hardware acceleration for it...

But of course it is possible. In fact, the library is designed to do such things. Like I stated in the readme file that came with the demos, this is about as slow as it can go. I didn't optimize anything yet.

Which, of course, it not a big problem and I think it wouldn't be a big challenge to compile it OS4 native, but what would you get? A PPC native GUI for the still 68k xad.library.
Sure, you could grab the sources from xad (I think it's OpenSource and they are on SourceForge) and compile it for OS4, but what will you get?
You would get a PPC native library but all the dearchivers plugins are still 68k and they are the guys who make all the work. So why do we not grab their sources and compile them for PPC? Because most (if not all) of them are 68k ASM and so you have to write them completely new, more or less
But it would be really nice to have at least PPC native plugins of the most common used formats, such as LHA, ZIP, GZIP, BZ2 and TAR (in that order ), all the others formats are so exotic that they can stay 68k (native RAR would be nice, but the unRAR of xad cannot handle the latest RAR archives, as I think, nothing except WinRAR can).

serpi: thats exactly my point and its a huge job but imho...XAD should be native within the os at all times but i guess that wont happen before a later version of os4.

anyway unrar3.4x sources is out there and id love to see this ported to native os4 , the old one we use today is 2.70 for native and 3.30 for 68k and xad has 3.1x or something iirc.

Winrar has made a totally new type of extractor/compressor now and its module based (abit like xad infact) and the new? standard 7zip is inside it aswell and more and more used here at work anyway .

7zip is iirc based upon lzh/lzx or something.

anyway this is
