Red Box of Doom when changing the Roassal Canvas of the Easle to Athens

by kilon alios

I get a MNU when I try to set Canvas in Easel (Roassal) to Athens. This is strange because I use also a very recent image and latest version from both Roassal and Athens at Win7 and I have no such problem. I am now on Macos 10.7 I had a similar problem when I tried to render text with Athens. Here is the stack.

It used to take ~20sec to load smalltalkhub.less in the previous version, now the compiled css takes around ~500ms. So it is 40x speedup. Thanks Nicolas! Regards, Esteban A. Maringolo

Re: [Pharo-dev] Understanding Roassal

by kilon alios

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 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.
