DiaCanvas is a generalized version of the drawing canvas used by DIA. It extends some features used by DIA and adds new ones, while preserving as many of the original features as possible. This project is no longer actively maintained. It is suggested that you try DiaCanvas2 instead.
No more DiaCanvas
There is no longer an option to download DiaCanvas from the sourceforge site. You should consider using DiaCanvas2 instead. It's just better...

DiaCanvas to SourceForge
Diacanvas has moved to Sourceforge. This should make the code available to everyone.
