Is your team open to external contributions as well ? I am still exploring
2 options

a) to use Roassal as a way to learn Athens

b) to use Roassal as a basis for my project

As a previous external contributor to Roassal I can say that Alexandre was very receptive to my contributions.� He was always constructive in his feedback :) which usually came in the form of refactoring my rough code into a better form.� I learned a lot from that (thanks Alex).��

I would be really excited if you based your project on Roassal.� I had/have aspirations to make Roassal interactive like a drawing package, but a few other tasks took precedence.� I could did up some proof of concept stuff I dig a while ago.� I think Roassal would provide a great basis for applications like:
* graphics editing like MS Visio
* mind mapping like Freemind (http://freemind.sourceforge.net/wiki/index.php/Main_Page)
* project management charting like MS Project

btw, have you seen ROSelection and ROExample>>rubberBand.� These originated from contributions of mine :) and are tangentially related to your goal.

cheers -ben

I did not expect that you would take such a generic approach to graphics ,
but from what I see I cant find a reason why I should not be using Roassal.
For the time being my whole focus is to create a Vector graphics editor, as
you can imagine this means a designer for vector graphics which it could
create a set of classes that could find their way back to Roassal. I dont
want to reinvent the wheel and I really lke to coordinate effort with
people with similar goals.

It is indeed.
Athens offers a nice way to build path. Once this will be fully integrated
in Roassal, we will have a flying machine.

yeap thank you , not only anti-aliasing works now but every look way
      
cooler, looks like Athens is quite an enhancement.

Ah okay. Then, you need to load the package RoassalAthens from the
      
repository of Roassal. But Smalltalkhub is down right now. Here is a mcz:
    
https://dl.dropboxusercontent.com/u/31543901/TMP/RoassalAthens-AlexandreBergel.14.mcz
    
Load this mcz file (e.g., drag and drop it in your Pharo window), then
      
execute "ROPlatform setCurrent: 'athens'. � and you should get antialiasing.

ROPlatform setCurrent: 'athens'.

gives me -> KeyNotFound: key 'athens' not found in Dictionary

'Athens' fails too.

I can verify lack of anti-aliasing also on win7.

I cant find an option to set anti-aliasing or Athens as backend in
        
Easel .
    
Loaded Roassal today with ->

Yes I am interested in Amber Roassal and also Roassal3d. Mostly on
          
Amber Roassal because I want to target tablets and phones and since I have
no desire to go through the App stores, javascript is my best option.
    
We are in sync

        
Another thing I have observed is that in all examples there is no
          
anti-aliasing which I find very weird because my vector editor which uses
Athens as well, has anti-aliased lines. Why is that ?
    
Strange. Have you tried to execute �ROPlatform setCurrent: �athens��.
        
You can use the easel to set the Athens canvas.
    
Else, simply use the Moose image, it comes with Athens and Roassal
        
properly installed.
    
I am very excited about Roassal , the more I look at the code and
          
the documentation the more I realize how flexible it is.
    
Thanks. We took care of having a lean and clean design. Although we
        
are quite satisfied, it is far from representing our ideal yet. One think I
would like to remove, is the rendering loop, having it just above Athens,
but below Roassal. We will work on this in January I think.
    
Is Roassal3d part of the Roassal project or is it an outside project
          
?
    
It is a new and different project.

        
Also do you plan integrating with Spec ? Will Roassal be a backend
          
for Spec ?
    
We have no plan for this right now. Glamour is well integrated with
        
Roassal. It should be easy to do it with Spec.

Hi!

          
So I took your advice and gave a good look to Roassal to learn
            
more about how to use Athens. First I want to congratulate the coders, I
was expecting a simple visualisation library for object graphs and what I
see is a full blown graphics library that can be used for many diffirent
kinds of graphical illustrations.
    
Thanks for your nice words :-)

          
I still however trying to understand the end goal of Roassal , is
            
there an end goal or is it generally code visualisation ?
    
The goal of Roassal is getting broader with the time. The main
          
objective of Roassal is to be a platform for data visualisation. So, as
soon as you have a bunch of data (e.g., plenty of numbers or any arbitrary
objects), then Roassal should give you the tools to visualize and interact
with your data.
    
Roassal is slowly moving from a tool for end-user to a platform on
          
which domain specific languages can be created. This is an important point
when reusing visualizations (e.g., ROTreeMapBuilder, ROMapBuilder,
ROMondrianViewBuilder are all compelling examples).
    
Roassal is currently being ported to Amber, which will probably
          
broaden the vision behind Roassal. Early examples may be found on:
http://pestefo.github.io/roamber/#
    
          
Also I wanted to ask if Roassal can do visual coding. By that I
            
mean visualize not only objects but messages inside methods so the users
with drag and drop code in a visual way.
    
Yes, Roassal is made for that. If there is something that Roassal
          
does not allow you to do, then let us know, we are a whole team ready to
polish Roassal.
    
I took a look at the examples but I see nowhere the use of bezier
            
curves , why is that ?
    
There is a few.

Try:
-=-=-=-=-=-=-=-=-=-=-=-=
"Source code: ROMondrianExample>>bezierCurveOn:"
"Preambule. It includes the initialization. "
| view rawView |
rawView := ROView new.
view := ROMondrianViewBuilder view: rawView.
"-------------"
"-------------"

view shape circle size: 10.
view nodes: (Collection withAllSubclasses).
view shape bezierLine.
view edgesFrom: #superclass.
view radialTreeLayout.
view center.

"-------------"
"-------------"
"Below is the initiation of the menu and opening the visualization"
ROEaselMorphic new populateMenuOn: view.
view open
-=-=-=-=-=-=-=-=-=-=-=-=

Have a look at the class ROSplineExample
It does not contains many examples, but you get enough to build
          
appealing visualization (e.g.,
